This is a list of major changes in SDL's version history.
---------------------------------------------------------------------------
2.0.4:
---------------------------------------------------------------------------
General:
* Added support for web applications using Emscripten, see docs/README-emscripten.md for more information
* Added support for web applications using Native Client (NaCl), see docs/README-nacl.md for more information
* Added an API to queue audio instead of using the audio callback:
SDL_QueueAudio(), SDL_GetQueuedAudioSize(), SDL_ClearQueuedAudio()
* Added events for audio device hot plug support:
SDL_AUDIODEVICEADDED, SDL_AUDIODEVICEREMOVED
* Added SDL_PointInRect()
* Added SDL_HasAVX2() to detect CPUs with AVX2 support
* Added SDL_SetWindowHitTest() to let apps treat parts of their SDL window like traditional window decorations (drag areas, resize areas)
* Added SDL_GetGrabbedWindow() to get the window that currently has input grab, if any
* Added SDL_RenderIsClipEnabled() to tell whether clipping is currently enabled in a renderer
* Added SDL_CaptureMouse() to capture the mouse to get events while the mouse is not in your window
* Added SDL_WarpMouseGlobal() to warp the mouse cursor in global screen space
* Added SDL_GetGlobalMouseState() to get the current mouse state outside of an SDL window
* Added a direction field to mouse wheel events to tell whether they are flipped (natural) or not
* Added GL_CONTEXT_RELEASE_BEHAVIOR GL attribute (maps to [WGL|GLX]_ARB_context_flush_control extension)
* Added EGL_KHR_create_context support to allow OpenGL ES version selection on some platforms
* Added NV12 and NV21 YUV texture support for OpenGL and OpenGL ES 2.0 renderers
* Added a Vivante video driver that is used on various SoC platforms
* Added an event SDL_RENDER_DEVICE_RESET that is sent from the D3D renderers when the D3D device is lost, and from Android's event loop when the GLES context had to be recreated
* Added a hint SDL_HINT_NO_SIGNAL_HANDLERS to disable SDL's built in signal handling
* Added a hint SDL_HINT_THREAD_STACK_SIZE to set the stack size of SDL's threads
* Added SDL_sqrtf(), SDL_tan(), and SDL_tanf() to the stdlib routines
* Improved support for WAV and BMP files with unusual chunks in them
* Renamed SDL_assert_data to SDL_AssertData and SDL_assert_state to SDL_AssertState
* Added a hint SDL_HINT_WINDOW_FRAME_USABLE_WHILE_CURSOR_HIDDEN to prevent window interaction while cursor is hidden
* Added SDL_GetDisplayDPI() to get the DPI information for a display
* Added SDL_JoystickCurrentPowerLevel() to get the battery level of a joystick
* Added SDL_JoystickFromInstanceID(), as a helper function, to get the SDL_Joystick* that an event is referring to.
* Added SDL_GameControllerFromInstanceID(), as a helper function, to get the SDL_GameController* that an event is referring to.
Windows:
* Added support for Windows Phone 8.1 and Windows 10/UWP (Universal Windows Platform)
* Timer resolution is now 1 ms by default, adjustable with the SDL_HINT_TIMER_RESOLUTION hint
* SDLmain no longer depends on the C runtime, so you can use the same .lib in both Debug and Release builds
* Added SDL_SetWindowsMessageHook() to set a function to be called for every windows message before TranslateMessage()
* Added a hint SDL_HINT_WINDOWS_ENABLE_MESSAGELOOP to control whether SDL_PumpEvents() processes the Windows message loop
* You can distinguish between real mouse and touch events by looking for SDL_TOUCH_MOUSEID in the mouse event "which" field
* SDL_SysWMinfo now contains the window HDC
* Added support for Unicode command line options
* Prevent beeping when Alt-key combos are pressed
* SDL_SetTextInputRect() re-positions the OS-rendered IME
* Added a hint SDL_HINT_WINDOWS_NO_CLOSE_ON_ALT_F4 to prevent generating SDL_WINDOWEVENT_CLOSE events when Alt-F4 is pressed
* Added a hint SDL_HINT_XINPUT_USE_OLD_JOYSTICK_MAPPING to use the old axis and button mapping for XInput devices (deprecated)
Mac OS X:
* Implemented drag-and-drop support
* Improved joystick hot-plug detection
* The SDL_WINDOWEVENT_EXPOSED window event is triggered in the appropriate situations
* Fixed relative mouse mode when the application loses/regains focus
* Fixed bugs related to transitioning to and from Spaces-aware fullscreen-desktop mode
* Fixed the refresh rate of display modes
* SDL_SysWMInfo is now ARC-compatible

Linux:
* Enabled building with Mir and Wayland support by default.
* Added IBus IME support
* Added a hint SDL_HINT_IME_INTERNAL_EDITING to control whether IBus should handle text editing internally instead of sending SDL_TEXTEDITING events
* Added a hint SDL_HINT_VIDEO_X11_NET_WM_PING to allow disabling _NET_WM_PING protocol handling in SDL_CreateWindow()
* Added support for multiple audio devices when using Pulseaudio
* Fixed duplicate mouse events when using relative mouse motion
iOS:
* Added support for iOS 8
* The SDL_WINDOW_ALLOW_HIGHDPI window flag now enables high-dpi support, and SDL_GL_GetDrawableSize() or SDL_GetRendererOutputSize() gets the window resolution in pixels
* SDL_GetWindowSize() and display mode sizes are in the "DPI-independent points" / "screen coordinates" coordinate space rather than pixels (matches OS X behavior)
* Added native resolution support for the iPhone 6 Plus
* Added support for MFi game controllers
* Added support for the hint SDL_HINT_ACCELEROMETER_AS_JOYSTICK
* Added sRGB OpenGL ES context support on iOS 7+

Android
================================================================================
Requirements:
Android SDK (version 12 or later)
http://developer.android.com/sdk/index.html
Android NDK r7 or later
http://developer.android.com/tools/sdk/ndk/index.html
Minimum API level supported by SDL: 10 (Android 2.3.3)
Joystick support is available for API level >=12 devices.
================================================================================
How the port works
================================================================================
- Android applications are Java-based, optionally with parts written in C
- As SDL apps are C-based, we use a small Java shim that uses JNI to talk to
the SDL library
- This means that your application C code must be placed inside an Android
Java project, along with some C support code that communicates with Java
- This eventually produces a standard Android .apk package
The Android Java code implements an "Activity" and can be found in:
android-project/src/org/libsdl/app/SDLActivity.java
The Java code loads your game code, the SDL shared library, and
dispatches to native functions implemented in the SDL library:
src/core/android/SDL_android.c
Your project must include some glue code that starts your main() routine:
src/main/android/SDL_android_main.c
================================================================================
Building an app
================================================================================
For simple projects you can use the script located at build-scripts/androidbuild.sh
There's two ways of using it:
androidbuild.sh com.yourcompany.yourapp < sources.list
androidbuild.sh com.yourcompany.yourapp source1.c source2.c ...sourceN.c
sources.list should be a text file with a source file name in each line
Filenames should be specified relative to the current directory, for example if
you are in the build-scripts directory and want to create the testgles.c test, you'll
run:
./androidbuild.sh org.libsdl.testgles ../test/testgles.c
One limitation of this script is that all sources provided will be aggregated into
a single directory, thus all your source files should have a unique name.
Once the project is complete the script will tell you where the debug APK is located.
If you want to create a signed release APK, you can use the project created by this
utility to generate it.
Finally, a word of caution: re running androidbuild.sh wipes any changes you may have
done in the build directory for the app!
For more complex projects, follow these instructions:
1. Copy the android-project directory wherever you want to keep your projects
and rename it to the name of your project.
2. Move or symlink this SDL directory into the <project>/jni directory
3. Edit <project>/jni/src/Android.mk to include your source files
4. Run 'ndk-build' (a script provided by the NDK). This compiles the C source
If you want to use the Eclipse IDE, skip to the Eclipse section below.
5. Create <project>/local.properties and use that to point to the Android SDK directory, by writing a line with the following form:
sdk.dir=PATH_TO_ANDROID_SDK
6. Run 'ant debug' in android/project. This compiles the .java and eventually
creates a .apk with the native code embedded
7. 'ant debug install' will push the apk to the device or emulator (if connected)
Here's an explanation of the files in the Android project, so you can customize them:
android-project/
AndroidManifest.xml - package manifest. Among others, it contains the class name
of the main Activity and the package name of the application.
build.properties - empty
build.xml - build description file, used by ant. The actual application name
is specified here.
default.properties - holds the target ABI for the application, android-10 and up
project.properties - holds the target ABI for the application, android-10 and up
local.properties - holds the SDK path, you should change this to the path to your SDK
jni/ - directory holding native code
jni/Android.mk - Android makefile that can call recursively the Android.mk files
in all subdirectories
jni/SDL/ - (symlink to) directory holding the SDL library files
jni/SDL/Android.mk - Android makefile for creating the SDL shared library
jni/src/ - directory holding your C/C++ source
jni/src/Android.mk - Android makefile that you should customize to include your
source code and any library references
res/ - directory holding resources for your application
res/drawable-* - directories holding icons for different phone hardware. Could be
one dir called "drawable".
res/layout/main.xml - Usually contains a file main.xml, which declares the screen layout.
We don't need it because we use the SDL video output.
res/values/strings.xml - strings used in your application, including the application name
shown on the phone.
src/org/libsdl/app/SDLActivity.java - the Java class handling the initialization and binding
to SDL. Be very careful changing this, as the SDL library relies
on this implementation.
================================================================================
Build an app with static linking of libSDL
================================================================================
This build uses the Android NDK module system.
Instructions:
1. Copy the android-project directory wherever you want to keep your projects
and rename it to the name of your project.
2. Rename <project>/jni/src/Android_static.mk to <project>/jni/src/Android.mk
(overwrite the existing one)
3. Edit <project>/jni/src/Android.mk to include your source files
4. create and export an environment variable named NDK_MODULE_PATH that points
to the parent directory of this SDL directory. e.g.:
export NDK_MODULE_PATH="$PWD"/..
5. Edit <project>/src/org/libsdl/app/SDLActivity.java and remove the call to
System.loadLibrary("SDL2").
6. Run 'ndk-build' (a script provided by the NDK). This compiles the C source
================================================================================
Customizing your application name
================================================================================
To customize your application name, edit AndroidManifest.xml and replace
"org.libsdl.app" with an identifier for your product package.
Then create a Java class extending SDLActivity and place it in a directory
under src matching your package, e.g.
src/com/gamemaker/game/MyGame.java
Here's an example of a minimal class file:
--- MyGame.java --------------------------
package com.gamemaker.game;
import org.libsdl.app.SDLActivity;
/**
* A sample wrapper class that just calls SDLActivity
*/
public class MyGame extends SDLActivity { }
------------------------------------------
Then replace "SDLActivity" in AndroidManifest.xml with the name of your
class, .e.g. "MyGame"
================================================================================
Customizing your application icon
================================================================================
Conceptually changing your icon is just replacing the "ic_launcher.png" files in
the drawable directories under the res directory. There are four directories for
different screen sizes. These can be replaced with one dir called "drawable",
containing an icon file "ic_launcher.png" with dimensions 48x48 or 72x72.
You may need to change the name of your icon in AndroidManifest.xml to match
this icon filename.
================================================================================
Loading assets
================================================================================
Any files you put in the "assets" directory of your android-project directory
will get bundled into the application package and you can load them using the
standard functions in SDL_rwops.h.
There are also a few Android specific functions that allow you to get other
useful paths for saving and loading data:
* SDL_AndroidGetInternalStoragePath()
* SDL_AndroidGetExternalStorageState()
* SDL_AndroidGetExternalStoragePath()
See SDL_system.h for more details on these functions.
The asset packaging system will, by default, compress certain file extensions.
SDL includes two asset file access mechanisms, the preferred one is the so
called "File Descriptor" method, which is faster and doesn't involve the Dalvik
GC, but given this method does not work on compressed assets, there is also the
"Input Stream" method, which is automatically used as a fall back by SDL. You
may want to keep this fact in mind when building your APK, specially when large
files are involved.
For more information on which extensions get compressed by default and how to
disable this behaviour, see for example:
http://ponystyle.com/blog/2010/03/26/dealing-with-asset-compression-in-android-apps/
================================================================================
Pause / Resume behaviour
================================================================================
If SDL is compiled with SDL_ANDROID_BLOCK_ON_PAUSE defined (the default),
the event loop will block itself when the app is paused (ie, when the user
returns to the main Android dashboard). Blocking is better in terms of battery
use, and it allows your app to spring back to life instantaneously after resume
(versus polling for a resume message).
Upon resume, SDL will attempt to restore the GL context automatically.
In modern devices (Android 3.0 and up) this will most likely succeed and your
app can continue to operate as it was.
However, there's a chance (on older hardware, or on systems under heavy load),
where the GL context can not be restored. In that case you have to listen for
a specific message, (which is not yet implemented!) and restore your textures
manually or quit the app (which is actually the kind of behaviour you'll see
under iOS, if the OS can not restore your GL context it will just kill your app)
================================================================================
Threads and the Java VM
================================================================================
For a quick tour on how Linux native threads interoperate with the Java VM, take
a look here: http://developer.android.com/guide/practices/jni.html
If you want to use threads in your SDL app, it's strongly recommended that you
do so by creating them using SDL functions. This way, the required attach/detach
handling is managed by SDL automagically. If you have threads created by other
means and they make calls to SDL functions, make sure that you call
Android_JNI_SetupThread() before doing anything else otherwise SDL will attach
your thread automatically anyway (when you make an SDL call), but it'll never
detach it.
================================================================================
Using STL
================================================================================
You can use STL in your project by creating an Application.mk file in the jni
folder and adding the following line:
APP_STL := stlport_static
For more information check out CPLUSPLUS-SUPPORT.html in the NDK documentation.
================================================================================
Additional documentation
================================================================================
The documentation in the NDK docs directory is very helpful in understanding the
build process and how to work with native code on the Android platform.
The best place to start is with docs/OVERVIEW.TXT
================================================================================
Using Eclipse
================================================================================
First make sure that you've installed Eclipse and the Android extensions as described here:
http://developer.android.com/tools/sdk/eclipse-adt.html
Once you've copied the SDL android project and customized it, you can create an Eclipse project from it:
* File -> New -> Other
* Select the Android -> Android Project wizard and click Next
* Enter the name you'd like your project to have
* Select "Create project from existing source" and browse for your project directory
* Make sure the Build Target is set to Android 3.1 (API 12)
* Click Finish
================================================================================
Using the emulator
================================================================================
There are some good tips and tricks for getting the most out of the
emulator here: http://developer.android.com/tools/devices/emulator.html
Especially useful is the info on setting up OpenGL ES 2.0 emulation.
Notice that this software emulator is incredibly slow and needs a lot of disk space.
Using a real device works better.
================================================================================
Troubleshooting
================================================================================
You can create and run an emulator from the Eclipse IDE:
* Window -> Android SDK and AVD Manager
You can see if adb can see any devices with the following command:
adb devices
You can see the output of log messages on the default device with:
adb logcat
You can push files to the device with:
adb push local_file remote_path_and_file
You can push files to the SD Card at /sdcard, for example:
adb push moose.dat /sdcard/moose.dat
You can see the files on the SD card with a shell command:
adb shell ls /sdcard/
You can start a command shell on the default device with:
adb shell
You can remove the library files of your project (and not the SDL lib files) with:
ndk-build clean
You can do a build with the following command:
ndk-build
You can see the complete command line that ndk-build is using by passing V=1 on the command line:
ndk-build V=1
If your application crashes in native code, you can use addr2line to convert the
addresses in the stack trace to lines in your code.
For example, if your crash looks like this:
I/DEBUG ( 31): signal 11 (SIGSEGV), code 2 (SEGV_ACCERR), fault addr 400085d0
I/DEBUG ( 31): r0 00000000 r1 00001000 r2 00000003 r3 400085d4
I/DEBUG ( 31): r4 400085d0 r5 40008000 r6 afd41504 r7 436c6a7c
I/DEBUG ( 31): r8 436c6b30 r9 435c6fb0 10 435c6f9c fp 4168d82c
I/DEBUG ( 31): ip 8346aff0 sp 436c6a60 lr afd1c8ff pc afd1c902 cpsr 60000030
I/DEBUG ( 31): #00 pc 0001c902 /system/lib/libc.so
I/DEBUG ( 31): #01 pc 0001ccf6 /system/lib/libc.so
I/DEBUG ( 31): #02 pc 000014bc /data/data/org.libsdl.app/lib/libmain.so
I/DEBUG ( 31): #03 pc 00001506 /data/data/org.libsdl.app/lib/libmain.so
You can see that there's a crash in the C library being called from the main code.
I run addr2line with the debug version of my code:
arm-eabi-addr2line -C -f -e obj/local/armeabi/libmain.so
and then paste in the number after "pc" in the call stack, from the line that I care about:
000014bc
I get output from addr2line showing that it's in the quit function, in testspriteminimal.c, on line 23.
You can add logging to your code to help show what's happening:
#include <android/log.h>
__android_log_print(ANDROID_LOG_INFO, "foo", "Something happened! x = %d", x);
If you need to build without optimization turned on, you can create a file called
"Application.mk" in the jni directory, with the following line in it:
APP_OPTIM := debug
================================================================================
Memory debugging
================================================================================
The best (and slowest) way to debug memory issues on Android is valgrind.
Valgrind has support for Android out of the box, just grab code using:
svn co svn://svn.valgrind.org/valgrind/trunk valgrind
... and follow the instructions in the file README.android to build it.
One thing I needed to do on Mac OS X was change the path to the toolchain,
and add ranlib to the environment variables:
export RANLIB=$NDKROOT/toolchains/arm-linux-androideabi-4.4.3/prebuilt/darwin-x86/bin/arm-linux-androideabi-ranlib
Once valgrind is built, you can create a wrapper script to launch your
application with it, changing org.libsdl.app to your package identifier:
--- start_valgrind_app -------------------
#!/system/bin/sh
export TMPDIR=/data/data/org.libsdl.app
exec /data/local/Inst/bin/valgrind --log-file=/sdcard/valgrind.log --error-limit=no $*
------------------------------------------
Then push it to the device:
adb push start_valgrind_app /data/local
and make it executable:
adb shell chmod 755 /data/local/start_valgrind_app
and tell Android to use the script to launch your application:
adb shell setprop wrap.org.libsdl.app "logwrapper /data/local/start_valgrind_app"
If the setprop command says "could not set property", it's likely that
your package name is too long and you should make it shorter by changing
AndroidManifest.xml and the path to your class file in android-project/src
You can then launch your application normally and waaaaaaaiiittt for it.
You can monitor the startup process with the logcat command above, and
when it's done (or even while it's running) you can grab the valgrind
output file:
adb pull /sdcard/valgrind.log
When you're done instrumenting with valgrind, you can disable the wrapper:
adb shell setprop wrap.org.libsdl.app ""
================================================================================
Why is API level 10 the minimum required?
================================================================================
API level 10 is the minimum required level at runtime (that is, on the device)
because SDL requires some functionality for running not
available on older devices. Since the incorporation of joystick support into SDL,
the minimum SDK required to *build* SDL is version 12. Devices running API levels
10-11 are still supported, only with the joystick functionality disabled.
Support for native OpenGL ES and ES2 applications was introduced in the NDK for
API level 4 and 8. EGL was made a stable API in the NDK for API level 9, which
has since then been obsoleted, with the recommendation to developers to bump the
required API level to 10.
As of this writing, according to http://developer.android.com/about/dashboards/index.html
about 90% of the Android devices accessing Google Play support API level 10 or
higher (March 2013).
================================================================================
A note regarding the use of the "dirty rectangles" rendering technique
================================================================================
If your app uses a variation of the "dirty rectangles" rendering technique,
where you only update a portion of the screen on each frame, you may notice a
variety of visual glitches on Android, that are not present on other platforms.
This is caused by SDL's use of EGL as the support system to handle OpenGL ES/ES2
contexts, in particular the use of the eglSwapBuffers function. As stated in the
documentation for the function "The contents of ancillary buffers are always
undefined after calling eglSwapBuffers".
Setting the EGL_SWAP_BEHAVIOR attribute of the surface to EGL_BUFFER_PRESERVED
is not possible for SDL as it requires EGL 1.4, available only on the API level
17+, so the only workaround available on this platform is to redraw the entire
screen each frame.
Reference: http://www.khronos.org/registry/egl/specs/EGLTechNote0001.html
================================================================================
Known issues
================================================================================
- The number of buttons reported for each joystick is hardcoded to be 36, which
is the current maximum number of buttons Android can report.
================================================================================
Matt Styles wrote a tutorial on building SDL for Android with Visual Studio:
http://trederia.blogspot.de/2017/03/building-sdl2-for-android-with-visual.html
The rest of this README covers the old style build process.
================================================================================
Requirements
================================================================================
Android SDK (version 16 or later)
https://developer.android.com/sdk/index.html
Android NDK r7 or later
https://developer.android.com/tools/sdk/ndk/index.html
Minimum API level supported by SDL: 10 (Android 2.3.3)
Joystick support is available for API level >= 12 devices.
================================================================================
How the port works
================================================================================
- Android applications are Java-based, optionally with parts written in C
- As SDL apps are C-based, we use a small Java shim that uses JNI to talk to
the SDL library
- This means that your application C code must be placed inside an Android
Java project, along with some C support code that communicates with Java
- This eventually produces a standard Android .apk package
The Android Java code implements an "Activity" and can be found in:
android-project/src/org/libsdl/app/SDLActivity.java
The Java code loads your game code, the SDL shared library, and
dispatches to native functions implemented in the SDL library:
src/core/android/SDL_android.c
Your project must include some glue code that starts your main() routine:
src/main/android/SDL_android_main.c
================================================================================
Building an app
================================================================================
For simple projects you can use the script located at build-scripts/androidbuild.sh
There's two ways of using it:
androidbuild.sh com.yourcompany.yourapp < sources.list
androidbuild.sh com.yourcompany.yourapp source1.c source2.c ...sourceN.c
sources.list should be a text file with a source file name in each line
Filenames should be specified relative to the current directory, for example if
you are in the build-scripts directory and want to create the testgles.c test, you'll
run:
./androidbuild.sh org.libsdl.testgles ../test/testgles.c
One limitation of this script is that all sources provided will be aggregated into
a single directory, thus all your source files should have a unique name.
Once the project is complete the script will tell you where the debug APK is located.
If you want to create a signed release APK, you can use the project created by this
utility to generate it.
Finally, a word of caution: re running androidbuild.sh wipes any changes you may have
done in the build directory for the app!
For more complex projects, follow these instructions:
1. Copy the android-project directory wherever you want to keep your projects
and rename it to the name of your project.
2. Move or symlink this SDL directory into the "<project>/jni" directory
3. Edit "<project>/jni/src/Android.mk" to include your source files
4. Run 'ndk-build' (a script provided by the NDK). This compiles the C source
If you want to use the Eclipse IDE, skip to the Eclipse section below.
5. Create "<project>/local.properties" and use that to point to the Android SDK directory, by writing a line with the following form:
sdk.dir=PATH_TO_ANDROID_SDK
6. Run 'ant debug' in android/project. This compiles the .java and eventually
creates a .apk with the native code embedded
7. 'ant debug install' will push the apk to the device or emulator (if connected)
Here's an explanation of the files in the Android project, so you can customize them:
android-project/
AndroidManifest.xml - package manifest. Among others, it contains the class name
of the main Activity and the package name of the application.
build.properties - empty
build.xml - build description file, used by ant. The actual application name
is specified here.
default.properties - holds the target ABI for the application, android-10 and up
project.properties - holds the target ABI for the application, android-10 and up
local.properties - holds the SDK path, you should change this to the path to your SDK
jni/ - directory holding native code
jni/Android.mk - Android makefile that can call recursively the Android.mk files
in all subdirectories
jni/SDL/ - (symlink to) directory holding the SDL library files
jni/SDL/Android.mk - Android makefile for creating the SDL shared library
jni/src/ - directory holding your C/C++ source
jni/src/Android.mk - Android makefile that you should customize to include your
source code and any library references
res/ - directory holding resources for your application
res/drawable-* - directories holding icons for different phone hardware. Could be
one dir called "drawable".
res/layout/main.xml - Usually contains a file main.xml, which declares the screen layout.
We don't need it because we use the SDL video output.
res/values/strings.xml - strings used in your application, including the application name
shown on the phone.
src/org/libsdl/app/SDLActivity.java - the Java class handling the initialization and binding
to SDL. Be very careful changing this, as the SDL library relies
on this implementation.
================================================================================
Build an app with static linking of libSDL
================================================================================
This build uses the Android NDK module system.
Instructions:
1. Copy the android-project directory wherever you want to keep your projects
and rename it to the name of your project.
2. Rename "<project>/jni/src/Android_static.mk" to "<project>/jni/src/Android.mk"
(overwrite the existing one)
3. Edit "<project>/jni/src/Android.mk" to include your source files
4. create and export an environment variable named NDK_MODULE_PATH that points
to the parent directory of this SDL directory. e.g.:
export NDK_MODULE_PATH="$PWD"/..
5. Edit "<project>/src/org/libsdl/app/SDLActivity.java" and remove the call to
System.loadLibrary("SDL2").
6. Run 'ndk-build' (a script provided by the NDK). This compiles the C source
================================================================================
Customizing your application name
================================================================================
To customize your application name, edit AndroidManifest.xml and replace
"org.libsdl.app" with an identifier for your product package.
Then create a Java class extending SDLActivity and place it in a directory
under src matching your package, e.g.
src/com/gamemaker/game/MyGame.java
Here's an example of a minimal class file:
--- MyGame.java --------------------------
package com.gamemaker.game;
import org.libsdl.app.SDLActivity;
/**
* A sample wrapper class that just calls SDLActivity
*/
public class MyGame extends SDLActivity { }
------------------------------------------
Then replace "SDLActivity" in AndroidManifest.xml with the name of your
class, .e.g. "MyGame"
================================================================================
Customizing your application icon
================================================================================
Conceptually changing your icon is just replacing the "ic_launcher.png" files in
the drawable directories under the res directory. There are four directories for
different screen sizes. These can be replaced with one dir called "drawable",
containing an icon file "ic_launcher.png" with dimensions 48x48 or 72x72.
You may need to change the name of your icon in AndroidManifest.xml to match
this icon filename.
================================================================================
Loading assets
================================================================================
Any files you put in the "assets" directory of your android-project directory
will get bundled into the application package and you can load them using the
standard functions in SDL_rwops.h.
There are also a few Android specific functions that allow you to get other
useful paths for saving and loading data:
* SDL_AndroidGetInternalStoragePath()
* SDL_AndroidGetExternalStorageState()
* SDL_AndroidGetExternalStoragePath()
See SDL_system.h for more details on these functions.
The asset packaging system will, by default, compress certain file extensions.
SDL includes two asset file access mechanisms, the preferred one is the so
called "File Descriptor" method, which is faster and doesn't involve the Dalvik
GC, but given this method does not work on compressed assets, there is also the
"Input Stream" method, which is automatically used as a fall back by SDL. You
may want to keep this fact in mind when building your APK, specially when large
files are involved.
For more information on which extensions get compressed by default and how to
disable this behaviour, see for example:
http://ponystyle.com/blog/2010/03/26/dealing-with-asset-compression-in-android-apps/
================================================================================
Pause / Resume behaviour
================================================================================
If SDL is compiled with SDL_ANDROID_BLOCK_ON_PAUSE defined (the default),
the event loop will block itself when the app is paused (ie, when the user
returns to the main Android dashboard). Blocking is better in terms of battery
use, and it allows your app to spring back to life instantaneously after resume
(versus polling for a resume message).
Upon resume, SDL will attempt to restore the GL context automatically.
In modern devices (Android 3.0 and up) this will most likely succeed and your
app can continue to operate as it was.
However, there's a chance (on older hardware, or on systems under heavy load),
where the GL context can not be restored. In that case you have to listen for
a specific message, (which is not yet implemented!) and restore your textures
manually or quit the app (which is actually the kind of behaviour you'll see
under iOS, if the OS can not restore your GL context it will just kill your app)
================================================================================

* Make sure the Build Target is set to Android 3.1 (API 12)
* Click Finish
================================================================================
Using the emulator
================================================================================
There are some good tips and tricks for getting the most out of the
emulator here: https://developer.android.com/tools/devices/emulator.html
Especially useful is the info on setting up OpenGL ES 2.0 emulation.
Notice that this software emulator is incredibly slow and needs a lot of disk space.

================================================================================
Troubleshooting
================================================================================
You can create and run an emulator from the Eclipse IDE:
* Window -> Android SDK and AVD Manager
You can see if adb can see any devices with the following command:
adb devices
You can see the output of log messages on the default device with:
adb logcat
You can push files to the device with:
adb push local_file remote_path_and_file
You can push files to the SD Card at /sdcard, for example:
adb push moose.dat /sdcard/moose.dat
You can see the files on the SD card with a shell command:
adb shell ls /sdcard/
You can start a command shell on the default device with:
adb shell
You can remove the library files of your project (and not the SDL lib files) with:
ndk-build clean
You can do a build with the following command:
ndk-build
You can see the complete command line that ndk-build is using by passing V=1 on the command line:
ndk-build V=1
If your application crashes in native code, you can use addr2line to convert the
addresses in the stack trace to lines in your code.
For example, if your crash looks like this:
I/DEBUG ( 31): signal 11 (SIGSEGV), code 2 (SEGV_ACCERR), fault addr 400085d0
I/DEBUG ( 31): r0 00000000 r1 00001000 r2 00000003 r3 400085d4
I/DEBUG ( 31): r4 400085d0 r5 40008000 r6 afd41504 r7 436c6a7c
I/DEBUG ( 31): r8 436c6b30 r9 435c6fb0 10 435c6f9c fp 4168d82c
I/DEBUG ( 31): ip 8346aff0 sp 436c6a60 lr afd1c8ff pc afd1c902 cpsr 60000030
I/DEBUG ( 31): #00 pc 0001c902 /system/lib/libc.so
I/DEBUG ( 31): #01 pc 0001ccf6 /system/lib/libc.so
I/DEBUG ( 31): #02 pc 000014bc /data/data/org.libsdl.app/lib/libmain.so
I/DEBUG ( 31): #03 pc 00001506 /data/data/org.libsdl.app/lib/libmain.so
You can see that there's a crash in the C library being called from the main code.
I run addr2line with the debug version of my code:
arm-eabi-addr2line -C -f -e obj/local/armeabi/libmain.so
and then paste in the number after "pc" in the call stack, from the line that I care about:
000014bc
I get output from addr2line showing that it's in the quit function, in testspriteminimal.c, on line 23.
You can add logging to your code to help show what's happening:
#include <android/log.h>
__android_log_print(ANDROID_LOG_INFO, "foo", "Something happened! x = %d", x);
If you need to build without optimization turned on, you can create a file called
"Application.mk" in the jni directory, with the following line in it:
APP_OPTIM := debug
================================================================================
Memory debugging
================================================================================
The best (and slowest) way to debug memory issues on Android is valgrind.
Valgrind has support for Android out of the box, just grab code using:
svn co svn://svn.valgrind.org/valgrind/trunk valgrind
... and follow the instructions in the file README.android to build it.
One thing I needed to do on Mac OS X was change the path to the toolchain,
and add ranlib to the environment variables:
export RANLIB=$NDKROOT/toolchains/arm-linux-androideabi-4.4.3/prebuilt/darwin-x86/bin/arm-linux-androideabi-ranlib
Once valgrind is built, you can create a wrapper script to launch your
application with it, changing org.libsdl.app to your package identifier:
--- start_valgrind_app -------------------
#!/system/bin/sh
export TMPDIR=/data/data/org.libsdl.app
exec /data/local/Inst/bin/valgrind --log-file=/sdcard/valgrind.log --error-limit=no $*
------------------------------------------
Then push it to the device:
adb push start_valgrind_app /data/local
and make it executable:
adb shell chmod 755 /data/local/start_valgrind_app
and tell Android to use the script to launch your application:
adb shell setprop wrap.org.libsdl.app "logwrapper /data/local/start_valgrind_app"
If the setprop command says "could not set property", it's likely that
your package name is too long and you should make it shorter by changing
AndroidManifest.xml and the path to your class file in android-project/src
You can then launch your application normally and waaaaaaaiiittt for it.
You can monitor the startup process with the logcat command above, and
when it's done (or even while it's running) you can grab the valgrind
output file:
adb pull /sdcard/valgrind.log
When you're done instrumenting with valgrind, you can disable the wrapper:
adb shell setprop wrap.org.libsdl.app ""
================================================================================
Graphics debugging
================================================================================
If you are developing on a compatible Tegra-based tablet, NVidia provides
Tegra Graphics Debugger at their website. Because SDL2 dynamically loads EGL
and GLES libraries, you must follow their instructions for installing the
interposer library on a rooted device. The non-rooted instructions are not
compatible with applications that use SDL2 for video.
The Tegra Graphics Debugger is available from NVidia here:
https://developer.nvidia.com/tegra-graphics-debugger
================================================================================

variety of visual glitches on Android, that are not present on other platforms.
This is caused by SDL's use of EGL as the support system to handle OpenGL ES/ES2
contexts, in particular the use of the eglSwapBuffers function. As stated in the
documentation for the function "The contents of ancillary buffers are always
undefined after calling eglSwapBuffers".
Setting the EGL_SWAP_BEHAVIOR attribute of the surface to EGL_BUFFER_PRESERVED
is not possible for SDL as it requires EGL 1.4, available only on the API level
17+, so the only workaround available on this platform is to redraw the entire
screen each frame.
Reference: http://www.khronos.org/registry/egl/specs/EGLTechNote0001.html

Known issues
================================================================================
- The number of buttons reported for each joystick is hardcoded to be 36, which
is the current maximum number of buttons Android can report.

CMake
================================================================================
================================================================================
(www.cmake.org)
SDL's build system was traditionally based on autotools. Over time, this
approach has suffered from several issues across the different supported
platforms.
To solve these problems, a new build system based on CMake is under development.
It works in parallel to the legacy system, so users can experiment with it
without complication.
While still experimental, the build system should be usable on the following
platforms:
* FreeBSD
* Linux
* VS.NET 2010
* MinGW and Msys
* OS X with support for XCode
================================================================================
Usage
================================================================================
Assuming the source for SDL is located at ~/sdl
cd ~
mkdir build
cd build
cmake ../sdl
This will build the static and dynamic versions of SDL in the ~/build directory.

DirectFB
DirectFB
========
Supports:
- Hardware YUV overlays
- OpenGL - software only
- 2D/3D accelerations (depends on directfb driver)
- multiple displays
- windows
What you need:
* DirectFB 1.0.1, 1.2.x, 1.3.0
* Kernel-Framebuffer support: required: vesafb, radeonfb ....
* Mesa 7.0.x - optional for OpenGL
/etc/directfbrc
This file should contain the following lines to make
your joystick work and avoid crashes:
------------------------
disable-module=joystick
disable-module=cle266
disable-module=cyber5k
no-linux-input-grab
------------------------
To disable to use x11 backend when DISPLAY variable is found use
export SDL_DIRECTFB_X11_CHECK=0
To disable the use of linux input devices, i.e. multimice/multikeyboard support,
use
export SDL_DIRECTFB_LINUX_INPUT=0
To use hardware accelerated YUV-overlays for YUV-textures, use:
export SDL_DIRECTFB_YUV_DIRECT=1
This is disabled by default. It will only support one
YUV texture, namely the first. Every other YUV texture will be
rendered in software.
In addition, you may use (directfb-1.2.x)
export SDL_DIRECTFB_YUV_UNDERLAY=1
to make the YUV texture an underlay. This will make the cursor to
be shown.
Simple Window Manager
=====================
The driver has support for a very, very basic window manager you may
want to use when running with "wm=default". Use
export SDL_DIRECTFB_WM=1
to enable basic window borders. In order to have the window title rendered,
you need to have the following font installed:
/usr/share/fonts/truetype/freefont/FreeSans.ttf
OpenGL Support
==============
The following instructions will give you *software* OpenGL. However this
works at least on all directfb supported platforms.

Dollar Gestures
===========================================================================
SDL provides an implementation of the $1 gesture recognition system. This allows for recording, saving, loading, and performing single stroke gestures.
Gestures can be performed with any number of fingers (the centroid of the fingers must follow the path of the gesture), but the number of fingers must be constant (a finger cannot go down in the middle of a gesture). The path of a gesture is considered the path from the time when the final finger went down, to the first time any finger comes up.
Dollar gestures are assigned an Id based on a hash function. This is guaranteed to remain constant for a given gesture. There is a (small) chance that two different gestures will be assigned the same ID. In this case, simply re-recording one of the gestures should result in a different ID.
Recording:
----------
To begin recording on a touch device call:
SDL_RecordGesture(SDL_TouchID touchId), where touchId is the id of the touch device you wish to record on, or -1 to record on all connected devices.
Recording terminates as soon as a finger comes up. Recording is acknowledged by an SDL_DOLLARRECORD event.
A SDL_DOLLARRECORD event is a dgesture with the following fields:
* event.dgesture.touchId - the Id of the touch used to record the gesture.
* event.dgesture.gestureId - the unique id of the recorded gesture.
Performing:
-----------
As long as there is a dollar gesture assigned to a touch, every finger-up event will also cause an SDL_DOLLARGESTURE event with the following fields:
* event.dgesture.touchId - the Id of the touch which performed the gesture.
* event.dgesture.gestureId - the unique id of the closest gesture to the performed stroke.
* event.dgesture.error - the difference between the gesture template and the actual performed gesture. Lower error is a better match.
* event.dgesture.numFingers - the number of fingers used to draw the stroke.
Most programs will want to define an appropriate error threshold and check to be sure that the error of a gesture is not abnormally high (an indicator that no gesture was performed).
Saving:
-------
To save a template, call SDL_SaveDollarTemplate(gestureId, dst) where gestureId is the id of the gesture you want to save, and dst is an SDL_RWops pointer to the file where the gesture will be stored.
To save all currently loaded templates, call SDL_SaveAllDollarTemplates(dst) where dst is an SDL_RWops pointer to the file where the gesture will be stored.
Both functions return the number of gestures successfully saved.
Loading:
--------
To load templates from a file, call SDL_LoadDollarTemplates(touchId,src) where touchId is the id of the touch to load to (or -1 to load to all touch devices), and src is an SDL_RWops pointer to a gesture save file.
SDL_LoadDollarTemplates returns the number of templates successfully loaded.
===========================================================================
Multi Gestures
===========================================================================
SDL provides simple support for pinch/rotate/swipe gestures.
Every time a finger is moved an SDL_MULTIGESTURE event is sent with the following fields:
* event.mgesture.touchId - the Id of the touch on which the gesture was performed.
* event.mgesture.x - the normalized x coordinate of the gesture. (0..1)
* event.mgesture.y - the normalized y coordinate of the gesture. (0..1)
* event.mgesture.dTheta - the amount that the fingers rotated during this motion.
* event.mgesture.dDist - the amount that the fingers pinched during this motion.
* event.mgesture.numFingers - the number of fingers used in the gesture.

Mercurial
=========
The latest development version of SDL is available via Mercurial.
Mercurial allows you to get up-to-the-minute fixes and enhancements;
as a developer works on a source tree, you can use "hg" to mirror that
source tree instead of waiting for an official release. Please look
at the Mercurial website ( http://mercurial.selenic.com/ ) for more
information on using hg, where you can also download software for
Mac OS X, Windows, and Unix systems.
hg clone http://hg.libsdl.org/SDL
If you are building SDL with an IDE, you will need to copy the file
include/SDL_config.h.default to include/SDL_config.h before building.
If you are building SDL via configure, you will need to run autogen.sh
before running configure.

iOS
======
==============================================================================
Building the Simple DirectMedia Layer for iOS 5.1+
==============================================================================
Requirements: Mac OS X 10.8 or later and the iOS 7+ SDK.
Instructions:
1. Open SDL.xcodeproj (located in Xcode-iOS/SDL) in Xcode.
2. Select your desired target, and hit build.
There are three build targets:
- libSDL.a:
Build SDL as a statically linked library
- testsdl:
Build a test program (there are known test failures which are fine)
- Template:
Package a project template together with the SDL for iPhone static libraries and copies of the SDL headers. The template includes proper references to the SDL library and headers, skeleton code for a basic SDL program, and placeholder graphics for the application icon and startup screen.
==============================================================================
Build SDL for iOS from the command line
==============================================================================
1. cd (PATH WHERE THE SDL CODE IS)/build-scripts
2. ./iosbuild.sh
If everything goes fine, you should see a build/ios directory, inside there's
two directories "lib" and "include".
"include" contains a copy of the SDL headers that you'll need for your project,
make sure to configure XCode to look for headers there.
"lib" contains find two files, libSDL2.a and libSDL2main.a, you have to add both
to your XCode project. These libraries contain three architectures in them,
armv6 for legacy devices, armv7, and i386 (for the simulator).
By default, iosbuild.sh will autodetect the SDK version you have installed using
xcodebuild -showsdks, and build for iOS >= 3.0, you can override this behaviour
by setting the MIN_OS_VERSION variable, ie:
MIN_OS_VERSION=4.2 ./iosbuild.sh
==============================================================================
Using the Simple DirectMedia Layer for iOS
==============================================================================
FIXME: This needs to be updated for the latest methods
Here is the easiest method:
1. Build the SDL library (libSDL2.a) and the iPhone SDL Application template.
2. Install the iPhone SDL Application template by copying it to one of Xcode's template directories. I recommend creating a directory called "SDL" in "/Developer/Platforms/iOS.platform/Developer/Library/Xcode/Project Templates/" and placing it there.
3. Start a new project using the template. The project should be immediately ready for use with SDL.
Here is a more manual method:
1. Create a new iOS view based application.
2. Build the SDL static library (libSDL2.a) for iOS and include them in your project. Xcode will ignore the library that is not currently of the correct architecture, hence your app will work both on iOS and in the iOS Simulator.
3. Include the SDL header files in your project.
4. Remove the ApplicationDelegate.h and ApplicationDelegate.m files -- SDL for iOS provides its own UIApplicationDelegate. Remove MainWindow.xib -- SDL for iOS produces its user interface programmatically.
5. Delete the contents of main.m and program your app as a regular SDL program instead. You may replace main.m with your own main.c, but you must tell Xcode not to use the project prefix file, as it includes Objective-C code.
==============================================================================
Notes -- Retina / High-DPI and window sizes
==============================================================================
Window and display mode sizes in SDL are in "screen coordinates" (or "points",
in Apple's terminology) rather than in pixels. On iOS this means that a window
created on an iPhone 6 will have a size in screen coordinates of 375 x 667,
rather than a size in pixels of 750 x 1334. All iOS apps are expected to
size their content based on screen coordinates / points rather than pixels,
as this allows different iOS devices to have different pixel densities
(Retina versus non-Retina screens, etc.) without apps caring too much.
By default SDL will not use the full pixel density of the screen on
Retina/high-dpi capable devices. Use the SDL_WINDOW_ALLOW_HIGHDPI flag when
creating your window to enable high-dpi support.
When high-dpi support is enabled, SDL_GetWindowSize and display mode sizes
will still be in "screen coordinates" rather than pixels, but the window will
have a much greater pixel density when the device supports it, and the
SDL_GL_GetDrawableSize or SDL_GetRendererOutputSize functions (depending on
whether raw OpenGL or the SDL_Render API is used) can be queried to determine
the size in pixels of the drawable screen framebuffer.
Some OpenGL ES functions such as glViewport expect sizes in pixels rather than
sizes in screen coordinates. When doing 2D rendering with OpenGL ES, an
orthographic projection matrix using the size in screen coordinates
(SDL_GetWindowSize) can be used in order to display content at the same scale
no matter whether a Retina device is used or not.
==============================================================================
Notes -- Application events
==============================================================================
On iOS the application goes through a fixed life cycle and you will get
notifications of state changes via application events. When these events
are delivered you must handle them in an event callback because the OS may
not give you any processing time after the events are delivered.
e.g.
int HandleAppEvents(void *userdata, SDL_Event *event)
{
switch (event->type)
{
case SDL_APP_TERMINATING:
/* Terminate the app.
Shut everything down before returning from this function.
*/
return 0;
case SDL_APP_LOWMEMORY:
/* You will get this when your app is paused and iOS wants more memory.
Release as much memory as possible.
*/
return 0;
case SDL_APP_WILLENTERBACKGROUND:
/* Prepare your app to go into the background. Stop loops, etc.
This gets called when the user hits the home button, or gets a call.
*/
return 0;
case SDL_APP_DIDENTERBACKGROUND:
/* This will get called if the user accepted whatever sent your app to the background.
If the user got a phone call and canceled it, you'll instead get an SDL_APP_DIDENTERFOREGROUND event and restart your loops.
When you get this, you have 5 seconds to save all your state or the app will be terminated.
Your app is NOT active at this point.
*/
return 0;
case SDL_APP_WILLENTERFOREGROUND:
/* This call happens when your app is coming back to the foreground.
Restore all your state here.
*/
return 0;
case SDL_APP_DIDENTERFOREGROUND:
/* Restart your loops here.
Your app is interactive and getting CPU again.
*/
return 0;
default:
/* No special processing, add it to the event queue */
return 1;
}
}
int main(int argc, char *argv[])
{
SDL_SetEventFilter(HandleAppEvents, NULL);
... run your main loop
return 0;
}
==============================================================================
Notes -- Accelerometer as Joystick
==============================================================================
SDL for iPhone supports polling the built in accelerometer as a joystick device. For an example on how to do this, see the accelerometer.c in the demos directory.
The main thing to note when using the accelerometer with SDL is that while the iPhone natively reports accelerometer as floating point values in units of g-force, SDL_JoystickGetAxis reports joystick values as signed integers. Hence, in order to convert between the two, some clamping and scaling is necessary on the part of the iPhone SDL joystick driver. To convert SDL_JoystickGetAxis reported values BACK to units of g-force, simply multiply the values by SDL_IPHONE_MAX_GFORCE / 0x7FFF.
==============================================================================
Notes -- OpenGL ES
==============================================================================
Your SDL application for iOS uses OpenGL ES for video by default.
OpenGL ES for iOS supports several display pixel formats, such as RGBA8 and RGB565, which provide a 32 bit and 16 bit color buffer respectively. By default, the implementation uses RGB565, but you may use RGBA8 by setting each color component to 8 bits in SDL_GL_SetAttribute.
If your application doesn't use OpenGL's depth buffer, you may find significant performance improvement by setting SDL_GL_DEPTH_SIZE to 0.
Finally, if your application completely redraws the screen each frame, you may find significant performance improvement by setting the attribute SDL_GL_RETAINED_BACKING to 0.
OpenGL ES on iOS doesn't use the traditional system-framebuffer setup provided in other operating systems. Special care must be taken because of this:
- The drawable Renderbuffer must be bound to the GL_RENDERBUFFER binding point when SDL_GL_SwapWindow is called.
- The drawable Framebuffer Object must be bound while rendering to the screen and when SDL_GL_SwapWindow is called.
- If multisample antialiasing (MSAA) is used and glReadPixels is used on the screen, the drawable framebuffer must be resolved to the MSAA resolve framebuffer (via glBlitFramebuffer or glResolveMultisampleFramebufferAPPLE), and the MSAA resolve framebuffer must be bound to the GL_READ_FRAMEBUFFER binding point, before glReadPixels is called.
The above objects can be obtained via SDL_GetWindowWMInfo (in SDL_syswm.h).
==============================================================================
Notes -- Keyboard
==============================================================================
The SDL keyboard API has been extended to support on-screen keyboards:
void SDL_StartTextInput()
-- enables text events and reveals the onscreen keyboard.
void SDL_StopTextInput()
-- disables text events and hides the onscreen keyboard.
SDL_bool SDL_IsTextInputActive()
-- returns whether or not text events are enabled (and the onscreen keyboard is visible)
==============================================================================
Notes -- Reading and Writing files
==============================================================================
Each application installed on iPhone resides in a sandbox which includes its own Application Home directory. Your application may not access files outside this directory.
Once your application is installed its directory tree looks like:
MySDLApp Home/
MySDLApp.app
Documents/
Library/
Preferences/
tmp/
When your SDL based iPhone application starts up, it sets the working directory to the main bundle (MySDLApp Home/MySDLApp.app), where your application resources are stored. You cannot write to this directory. Instead, I advise you to write document files to "../Documents/" and preferences to "../Library/Preferences".
More information on this subject is available here:
http://developer.apple.com/library/ios/#documentation/iPhone/Conceptual/iPhoneOSProgrammingGuide/Introduction/Introduction.html
==============================================================================
Notes -- iPhone SDL limitations
==============================================================================
Windows:
Full-size, single window applications only. You cannot create multi-window SDL applications for iPhone OS. The application window will fill the display, though you have the option of turning on or off the menu-bar (pass SDL_CreateWindow the flag SDL_WINDOW_BORDERLESS).
Textures:
The optimal texture formats on iOS are SDL_PIXELFORMAT_ABGR8888, SDL_PIXELFORMAT_ABGR8888, SDL_PIXELFORMAT_BGR888, and SDL_PIXELFORMAT_RGB24 pixel formats.
Loading Shared Objects:
This is disabled by default since it seems to break the terms of the iOS SDK agreement for iOS versions prior to iOS 8. It can be re-enabled in SDL_config_iphoneos.h.
==============================================================================
Game Center
==============================================================================
Game Center integration might require that you break up your main loop in order to yield control back to the system. In other words, instead of running an endless main loop, you run each frame in a callback function, using:
int SDL_iPhoneSetAnimationCallback(SDL_Window * window, int interval, void (*callback)(void*), void *callbackParam);
This will set up the given function to be called back on the animation callback, and then you have to return from main() to let the Cocoa event loop run.
e.g.
extern "C"
void ShowFrame(void*)
{
... do event handling, frame logic and rendering ...
}
int main(int argc, char *argv[])
{
... initialize game ...
#if __IPHONEOS__
// Initialize the Game Center for scoring and matchmaking
InitGameCenter();
// Set up the game to run in the window animation callback on iOS
// so that Game Center and so forth works correctly.
SDL_iPhoneSetAnimationCallback(window, 1, ShowFrame, NULL);
#else
while ( running ) {
ShowFrame(0);
DelayFrame();
}
#endif
return 0;

- testsdl:
Build a test program (there are known test failures which are fine)
- Template:
Package a project template together with the SDL for iPhone static libraries and copies of the SDL headers. The template includes proper references to the SDL library and headers, skeleton code for a basic SDL program, and placeholder graphics for the application icon and startup screen.
==============================================================================
Build SDL for iOS from the command line
==============================================================================
1. cd (PATH WHERE THE SDL CODE IS)/build-scripts
2. ./iosbuild.sh
If everything goes fine, you should see a build/ios directory, inside there's
two directories "lib" and "include".
"include" contains a copy of the SDL headers that you'll need for your project,
make sure to configure XCode to look for headers there.
"lib" contains find two files, libSDL2.a and libSDL2main.a, you have to add both
to your XCode project. These libraries contain three architectures in them,
armv6 for legacy devices, armv7, and i386 (for the simulator).
By default, iosbuild.sh will autodetect the SDK version you have installed using
xcodebuild -showsdks, and build for iOS >= 3.0, you can override this behaviour
by setting the MIN_OS_VERSION variable, ie:
MIN_OS_VERSION=4.2 ./iosbuild.sh
==============================================================================
Using the Simple DirectMedia Layer for iOS
==============================================================================
FIXME: This needs to be updated for the latest methods
Here is the easiest method:
1. Build the SDL library (libSDL2.a) and the iPhone SDL Application template.
2. Install the iPhone SDL Application template by copying it to one of Xcode's template directories. I recommend creating a directory called "SDL" in "/Developer/Platforms/iOS.platform/Developer/Library/Xcode/Project Templates/" and placing it there.
3. Start a new project using the template. The project should be immediately ready for use with SDL.
Here is a more manual method:
1. Create a new iOS view based application.
2. Build the SDL static library (libSDL2.a) for iOS and include them in your project. Xcode will ignore the library that is not currently of the correct architecture, hence your app will work both on iOS and in the iOS Simulator.
3. Include the SDL header files in your project.
4. Remove the ApplicationDelegate.h and ApplicationDelegate.m files -- SDL for iOS provides its own UIApplicationDelegate. Remove MainWindow.xib -- SDL for iOS produces its user interface programmatically.
5. Delete the contents of main.m and program your app as a regular SDL program instead. You may replace main.m with your own main.c, but you must tell Xcode not to use the project prefix file, as it includes Objective-C code.
==============================================================================
Notes -- Retina / High-DPI and window sizes
==============================================================================
Window and display mode sizes in SDL are in "screen coordinates" (or "points",
in Apple's terminology) rather than in pixels. On iOS this means that a window
created on an iPhone 6 will have a size in screen coordinates of 375 x 667,
rather than a size in pixels of 750 x 1334. All iOS apps are expected to
size their content based on screen coordinates / points rather than pixels,
as this allows different iOS devices to have different pixel densities
(Retina versus non-Retina screens, etc.) without apps caring too much.
By default SDL will not use the full pixel density of the screen on
Retina/high-dpi capable devices. Use the SDL_WINDOW_ALLOW_HIGHDPI flag when
creating your window to enable high-dpi support.
When high-dpi support is enabled, SDL_GetWindowSize() and display mode sizes
will still be in "screen coordinates" rather than pixels, but the window will
have a much greater pixel density when the device supports it, and the
SDL_GL_GetDrawableSize() or SDL_GetRendererOutputSize() functions (depending on
whether raw OpenGL or the SDL_Render API is used) can be queried to determine
the size in pixels of the drawable screen framebuffer.
Some OpenGL ES functions such as glViewport expect sizes in pixels rather than
sizes in screen coordinates. When doing 2D rendering with OpenGL ES, an
orthographic projection matrix using the size in screen coordinates
(SDL_GetWindowSize()) can be used in order to display content at the same scale
no matter whether a Retina device is used or not.
==============================================================================
Notes -- Application events
==============================================================================
On iOS the application goes through a fixed life cycle and you will get
notifications of state changes via application events. When these events
are delivered you must handle them in an event callback because the OS may
not give you any processing time after the events are delivered.
e.g.
int HandleAppEvents(void *userdata, SDL_Event *event)
{
switch (event->type)
{
case SDL_APP_TERMINATING:
/* Terminate the app.
Shut everything down before returning from this function.
*/
return 0;
case SDL_APP_LOWMEMORY:
/* You will get this when your app is paused and iOS wants more memory.
Release as much memory as possible.
*/
return 0;
case SDL_APP_WILLENTERBACKGROUND:
/* Prepare your app to go into the background. Stop loops, etc.
This gets called when the user hits the home button, or gets a call.
*/
return 0;
case SDL_APP_DIDENTERBACKGROUND:
/* This will get called if the user accepted whatever sent your app to the background.
If the user got a phone call and canceled it, you'll instead get an SDL_APP_DIDENTERFOREGROUND event and restart your loops.
When you get this, you have 5 seconds to save all your state or the app will be terminated.
Your app is NOT active at this point.
*/
return 0;
case SDL_APP_WILLENTERFOREGROUND:
/* This call happens when your app is coming back to the foreground.
Restore all your state here.
*/
return 0;
case SDL_APP_DIDENTERFOREGROUND:
/* Restart your loops here.
Your app is interactive and getting CPU again.
*/
return 0;
default:
/* No special processing, add it to the event queue */
return 1;
}
}
int main(int argc, char *argv[])
{
SDL_SetEventFilter(HandleAppEvents, NULL);
... run your main loop
return 0;
}
==============================================================================
Notes -- Accelerometer as Joystick
==============================================================================
SDL for iPhone supports polling the built in accelerometer as a joystick device. For an example on how to do this, see the accelerometer.c in the demos directory.
The main thing to note when using the accelerometer with SDL is that while the iPhone natively reports accelerometer as floating point values in units of g-force, SDL_JoystickGetAxis() reports joystick values as signed integers. Hence, in order to convert between the two, some clamping and scaling is necessary on the part of the iPhone SDL joystick driver. To convert SDL_JoystickGetAxis() reported values BACK to units of g-force, simply multiply the values by SDL_IPHONE_MAX_GFORCE / 0x7FFF.
==============================================================================
Notes -- OpenGL ES
==============================================================================
Your SDL application for iOS uses OpenGL ES for video by default.
OpenGL ES for iOS supports several display pixel formats, such as RGBA8 and RGB565, which provide a 32 bit and 16 bit color buffer respectively. By default, the implementation uses RGB565, but you may use RGBA8 by setting each color component to 8 bits in SDL_GL_SetAttribute().
If your application doesn't use OpenGL's depth buffer, you may find significant performance improvement by setting SDL_GL_DEPTH_SIZE to 0.
Finally, if your application completely redraws the screen each frame, you may find significant performance improvement by setting the attribute SDL_GL_RETAINED_BACKING to 0.
OpenGL ES on iOS doesn't use the traditional system-framebuffer setup provided in other operating systems. Special care must be taken because of this:
- The drawable Renderbuffer must be bound to the GL_RENDERBUFFER binding point when SDL_GL_SwapWindow() is called.
- The drawable Framebuffer Object must be bound while rendering to the screen and when SDL_GL_SwapWindow() is called.
- If multisample antialiasing (MSAA) is used and glReadPixels is used on the screen, the drawable framebuffer must be resolved to the MSAA resolve framebuffer (via glBlitFramebuffer or glResolveMultisampleFramebufferAPPLE), and the MSAA resolve framebuffer must be bound to the GL_READ_FRAMEBUFFER binding point, before glReadPixels is called.
The above objects can be obtained via SDL_GetWindowWMInfo() (in SDL_syswm.h).
==============================================================================
Notes -- Keyboard
==============================================================================
The SDL keyboard API has been extended to support on-screen keyboards:
void SDL_StartTextInput()
-- enables text events and reveals the onscreen keyboard.
void SDL_StopTextInput()
-- disables text events and hides the onscreen keyboard.
SDL_bool SDL_IsTextInputActive()
-- returns whether or not text events are enabled (and the onscreen keyboard is visible)
==============================================================================
Notes -- Reading and Writing files
==============================================================================
Each application installed on iPhone resides in a sandbox which includes its own Application Home directory. Your application may not access files outside this directory.
Once your application is installed its directory tree looks like:
MySDLApp Home/
MySDLApp.app
Documents/
Library/
Preferences/
tmp/
When your SDL based iPhone application starts up, it sets the working directory to the main bundle (MySDLApp Home/MySDLApp.app), where your application resources are stored. You cannot write to this directory. Instead, I advise you to write document files to "../Documents/" and preferences to "../Library/Preferences".
More information on this subject is available here:
http://developer.apple.com/library/ios/#documentation/iPhone/Conceptual/iPhoneOSProgrammingGuide/Introduction/Introduction.html
==============================================================================
Notes -- iPhone SDL limitations
==============================================================================
Windows:
Full-size, single window applications only. You cannot create multi-window SDL applications for iPhone OS. The application window will fill the display, though you have the option of turning on or off the menu-bar (pass SDL_CreateWindow() the flag SDL_WINDOW_BORDERLESS).
Textures:
The optimal texture formats on iOS are SDL_PIXELFORMAT_ABGR8888, SDL_PIXELFORMAT_ABGR8888, SDL_PIXELFORMAT_BGR888, and SDL_PIXELFORMAT_RGB24 pixel formats.
Loading Shared Objects:
This is disabled by default since it seems to break the terms of the iOS SDK agreement for iOS versions prior to iOS 8. It can be re-enabled in SDL_config_iphoneos.h.
==============================================================================
Game Center
==============================================================================
Game Center integration might require that you break up your main loop in order to yield control back to the system. In other words, instead of running an endless main loop, you run each frame in a callback function, using:
int SDL_iPhoneSetAnimationCallback(SDL_Window * window, int interval, void (*callback)(void*), void *callbackParam);
This will set up the given function to be called back on the animation callback, and then you have to return from main() to let the Cocoa event loop run.
e.g.
extern "C"
void ShowFrame(void*)
{
... do event handling, frame logic and rendering ...
}
int main(int argc, char *argv[])
{
... initialize game ...
#if __IPHONEOS__
// Initialize the Game Center for scoring and matchmaking
InitGameCenter();
// Set up the game to run in the window animation callback on iOS
// so that Game Center and so forth works correctly.
SDL_iPhoneSetAnimationCallback(window, 1, ShowFrame, NULL);
#else
while ( running ) {
ShowFrame(0);
DelayFrame();
}
#endif
return 0;
}
==============================================================================
Deploying to older versions of iOS
==============================================================================
SDL supports deploying to older versions of iOS than are supported by the latest version of Xcode, all the way back to iOS 6.1
In order to do that you need to download an older version of Xcode:
https://developer.apple.com/download/more/?name=Xcode
Open the package contents of the older Xcode and your newer version of Xcode and copy over the folders in Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
Then open the file Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/SDKSettings.plist and add the versions of iOS you want to deploy to the key Root/DefaultProperties/DEPLOYMENT_TARGET_SUGGESTED_VALUES
Open your project and set your deployment target to the desired version of iOS
Finally, remove GameController from the list of frameworks linked by your application and edit the build settings for "Other Linker Flags" and add -weak_framework GameController

- libsamplerate0-dev lets SDL optionally link to libresamplerate at runtime
for higher-quality audio resampling. SDL will work without it if the library
is missing, so it's safe to build in support even if the end user doesn't
have this library installed.
- DirectFB isn't included because the configure script (currently) fails to find
it at all. You can do "sudo apt-get install libdirectfb-dev" and fix the
configure script to include DirectFB support. Send patches. :)

Mac OS X
==============================================================================
These instructions are for people using Apple's Mac OS X (pronounced
"ten").
From the developer's point of view, OS X is a sort of hybrid Mac and
Unix system, and you have the option of using either traditional
command line tools or Apple's IDE Xcode.
To build SDL using the command line, use the standard configure and make
process:
./configure
make
sudo make install
You can also build SDL as a Universal library (a single binary for both
32-bit and 64-bit Intel architectures), on Mac OS X 10.7 and newer, by using
the gcc-fat.sh script in build-scripts:
mkdir mybuild
cd mybuild
CC=$PWD/../build-scripts/gcc-fat.sh CXX=$PWD/../build-scripts/g++fat.sh ../configure
make
sudo make install
This script builds SDL with 10.5 ABI compatibility on i386 and 10.6
ABI compatibility on x86_64 architectures. For best compatibility you
should compile your application the same way.
Please note that building SDL requires at least Xcode 4.6 and the 10.7 SDK
(even if you target back to 10.5 systems). PowerPC support for Mac OS X has
been officially dropped as of SDL 2.0.2.
To use the library once it's built, you essential have two possibilities:
use the traditional autoconf/automake/make method, or use Xcode.
==============================================================================
Caveats for using SDL with Mac OS X
==============================================================================
Some things you have to be aware of when using SDL on Mac OS X:
- If you register your own NSApplicationDelegate (using [NSApp setDelegate:]),
SDL will not register its own. This means that SDL will not terminate using
SDL_Quit if it receives a termination request, it will terminate like a
normal app, and it will not send a SDL_DROPFILE when you request to open a
file with the app. To solve these issues, put the following code in your
NSApplicationDelegate implementation:
- (NSApplicationTerminateReply)applicationShouldTerminate:(NSApplication *)sender
{
if (SDL_GetEventState(SDL_QUIT) == SDL_ENABLE) {
SDL_Event event;
event.type = SDL_QUIT;
SDL_PushEvent(&event);
}
return NSTerminateCancel;
}
- (BOOL)application:(NSApplication *)theApplication openFile:(NSString *)filename
{
if (SDL_GetEventState(SDL_DROPFILE) == SDL_ENABLE) {
SDL_Event event;
event.type = SDL_DROPFILE;
event.drop.file = SDL_strdup([filename UTF8String]);
return (SDL_PushEvent(&event) > 0);
}
return NO;
}
==============================================================================
Using the Simple DirectMedia Layer with a traditional Makefile
==============================================================================
An existing autoconf/automake build system for your SDL app has good chances
to work almost unchanged on OS X. However, to produce a "real" Mac OS X binary
that you can distribute to users, you need to put the generated binary into a
so called "bundle", which basically is a fancy folder with a name like
"MyCoolGame.app".
To get this build automatically, add something like the following rule to
your Makefile.am:
bundle_contents = APP_NAME.app/Contents
APP_NAME_bundle: EXE_NAME
mkdir -p $(bundle_contents)/MacOS
mkdir -p $(bundle_contents)/Resources
echo "APPL????" > $(bundle_contents)/PkgInfo
$(INSTALL_PROGRAM) $< $(bundle_contents)/MacOS/
You should replace EXE_NAME with the name of the executable. APP_NAME is what
will be visible to the user in the Finder. Usually it will be the same
as EXE_NAME but capitalized. E.g. if EXE_NAME is "testgame" then APP_NAME
usually is "TestGame". You might also want to use @PACKAGE@ to use the package
name as specified in your configure.in file.
If your project builds more than one application, you will have to do a bit
more. For each of your target applications, you need a separate rule.
If you want the created bundles to be installed, you may want to add this
rule to your Makefile.am:
install-exec-hook: APP_NAME_bundle
rm -rf $(DESTDIR)$(prefix)/Applications/APP_NAME.app
mkdir -p $(DESTDIR)$(prefix)/Applications/
cp -r $< /$(DESTDIR)$(prefix)Applications/
This rule takes the Bundle created by the rule from step 3 and installs them
into $(DESTDIR)$(prefix)/Applications/.
Again, if you want to install multiple applications, you will have to augment
the make rule accordingly.
But beware! That is only part of the story! With the above, you end up with
a bare bone .app bundle, which is double clickable from the Finder. But
there are some more things you should do before shipping your product...
1) The bundle right now probably is dynamically linked against SDL. That
means that when you copy it to another computer, *it will not run*,
unless you also install SDL on that other computer. A good solution
for this dilemma is to static link against SDL. On OS X, you can
achieve that by linking against the libraries listed by
sdl-config --static-libs
instead of those listed by
sdl-config --libs
Depending on how exactly SDL is integrated into your build systems, the
way to achieve that varies, so I won't describe it here in detail
2) Add an 'Info.plist' to your application. That is a special XML file which
contains some meta-information about your application (like some copyright
information, the version of your app, the name of an optional icon file,
and other things). Part of that information is displayed by the Finder
when you click on the .app, or if you look at the "Get Info" window.
More information about Info.plist files can be found on Apple's homepage.
As a final remark, let me add that I use some of the techniques (and some
variations of them) in Exult and ScummVM; both are available in source on
the net, so feel free to take a peek at them for inspiration!
==============================================================================
Using the Simple DirectMedia Layer with Xcode
==============================================================================
These instructions are for using Apple's Xcode IDE to build SDL applications.
- First steps
The first thing to do is to unpack the Xcode.tar.gz archive in the
top level SDL directory (where the Xcode.tar.gz archive resides).
Because Stuffit Expander will unpack the archive into a subdirectory,
you should unpack the archive manually from the command line:
cd [path_to_SDL_source]
tar zxf Xcode.tar.gz
This will create a new folder called Xcode, which you can browse
normally from the Finder.
- Building the Framework
The SDL Library is packaged as a framework bundle, an organized
relocatable folder hierarchy of executable code, interface headers,
and additional resources. For practical purposes, you can think of a
framework as a more user and system-friendly shared library, whose library
file behaves more or less like a standard UNIX shared library.
To build the framework, simply open the framework project and build it.
By default, the framework bundle "SDL.framework" is installed in
/Library/Frameworks. Therefore, the testers and project stationary expect
it to be located there. However, it will function the same in any of the
following locations:
~/Library/Frameworks
/Local/Library/Frameworks
/System/Library/Frameworks
- Build Options
There are two "Build Styles" (See the "Targets" tab) for SDL.
"Deployment" should be used if you aren't tweaking the SDL library.
"Development" should be used to debug SDL apps or the library itself.
- Building the Testers
Open the SDLTest project and build away!
- Using the Project Stationary
Copy the stationary to the indicated folders to access it from
the "New Project" and "Add target" menus. What could be easier?
- Setting up a new project by hand
Some of you won't want to use the Stationary so I'll give some tips:
* Create a new "Cocoa Application"
* Add src/main/macosx/SDLMain.m , .h and .nib to your project
* Remove "main.c" from your project
* Remove "MainMenu.nib" from your project
* Add "$(HOME)/Library/Frameworks/SDL.framework/Headers" to include path
* Add "$(HOME)/Library/Frameworks" to the frameworks search path
* Add "-framework SDL -framework Foundation -framework AppKit" to "OTHER_LDFLAGS"
* Set the "Main Nib File" under "Application Settings" to "SDLMain.nib"
* Add your files
* Clean and build
- Building from command line
Use pbxbuild in the same directory as your .pbproj file
- Running your app
You can send command line args to your app by either invoking it from
the command line (in *.app/Contents/MacOS) or by entering them in the
"Executables" panel of the target settings.
- Implementation Notes
Some things that may be of interest about how it all works...
* Working directory
As defined in the SDL_main.m file, the working directory of your SDL app
is by default set to its parent. You may wish to change this to better
suit your needs.
* You have a Cocoa App!
Your SDL app is essentially a Cocoa application. When your app
starts up and the libraries finish loading, a Cocoa procedure is called,
which sets up the working directory and calls your main() method.
You are free to modify your Cocoa app with generally no consequence
to SDL. You cannot, however, easily change the SDL window itself.
Functionality may be added in the future to help this.
Known bugs are listed in the file "BUGS"

Copy the stationary to the indicated folders to access it from
the "New Project" and "Add target" menus. What could be easier?
- Setting up a new project by hand
Some of you won't want to use the Stationary so I'll give some tips:
* Create a new "Cocoa Application"
* Add src/main/macosx/SDLMain.m , .h and .nib to your project
* Remove "main.c" from your project
* Remove "MainMenu.nib" from your project
* Add "$(HOME)/Library/Frameworks/SDL.framework/Headers" to include path
* Add "$(HOME)/Library/Frameworks" to the frameworks search path
* Add "-framework SDL -framework Foundation -framework AppKit" to "OTHER_LDFLAGS"
* Set the "Main Nib File" under "Application Settings" to "SDLMain.nib"
* Add your files
* Clean and build
- Building from command line
Use pbxbuild in the same directory as your .pbproj file
- Running your app
You can send command line args to your app by either invoking it from
the command line (in *.app/Contents/MacOS) or by entering them in the
"Executables" panel of the target settings.
- Implementation Notes
Some things that may be of interest about how it all works...
* Working directory
As defined in the SDL_main.m file, the working directory of your SDL app
is by default set to its parent. You may wish to change this to better
suit your needs.
* You have a Cocoa App!
Your SDL app is essentially a Cocoa application. When your app
starts up and the libraries finish loading, a Cocoa procedure is called,
which sets up the working directory and calls your main() method.
You are free to modify your Cocoa app with generally no consequence
to SDL. You cannot, however, easily change the SDL window itself.
Functionality may be added in the future to help this.
Known bugs are listed in the file "BUGS.txt".

Pandora
=====================================================================
=====================================================================
( http://openpandora.org/ )
- A pandora specific video driver was written to allow SDL 2.0 with OpenGL ES
support to work on the pandora under the framebuffer. This driver do not have
input support for now, so if you use it you will have to add your own control code.
The video driver name is "pandora" so if you have problem running it from
the framebuffer, try to set the following variable before starting your application :
"export SDL_VIDEODRIVER=pandora"
- OpenGL ES support was added to the x11 driver, so it's working like the normal
x11 driver one with OpenGLX support, with SDL input event's etc..

Porting
=======
* Porting To A New Platform
The first thing you have to do when porting to a new platform, is look at
include/SDL_platform.h and create an entry there for your operating system.
The standard format is __PLATFORM__, where PLATFORM is the name of the OS.
Ideally SDL_platform.h will be able to auto-detect the system it's building
on based on C preprocessor symbols.
There are two basic ways of building SDL at the moment:
1. The "UNIX" way: ./configure; make; make install
If you have a GNUish system, then you might try this. Edit configure.in,
take a look at the large section labelled:
"Set up the configuration based on the host platform!"
Add a section for your platform, and then re-run autogen.sh and build!
2. Using an IDE:
If you're using an IDE or other non-configure build system, you'll probably
want to create a custom SDL_config.h for your platform. Edit SDL_config.h,
add a section for your platform, and create a custom SDL_config_{platform}.h,
based on SDL_config.h.minimal and SDL_config.h.in
Add the top level include directory to the header search path, and then add
the following sources to the project:
src/*.c
src/atomic/*.c
src/audio/*.c
src/cpuinfo/*.c
src/events/*.c
src/file/*.c
src/haptic/*.c
src/joystick/*.c
src/power/*.c
src/render/*.c
src/stdlib/*.c
src/thread/*.c
src/timer/*.c
src/video/*.c
src/audio/disk/*.c
src/audio/dummy/*.c
src/filesystem/dummy/*.c
src/video/dummy/*.c
src/haptic/dummy/*.c
src/joystick/dummy/*.c
src/main/dummy/*.c
src/thread/generic/*.c
src/timer/dummy/*.c
src/loadso/dummy/*.c
Once you have a working library without any drivers, you can go back to each
of the major subsystems and start implementing drivers for your platform.
If you have any questions, don't hesitate to ask on the SDL mailing list:
http://www.libsdl.org/mailing-list.php
Enjoy!

Raspberry Pi
================================================================================
Requirements:
Raspbian (other Linux distros may work as well).
================================================================================
Features
================================================================================
* Works without X11
* Hardware accelerated OpenGL ES 2.x
* Sound via ALSA
* Input (mouse/keyboard/joystick) via EVDEV
* Hotplugging of input devices via UDEV
================================================================================
Raspbian Build Dependencies
================================================================================
sudo apt-get install libudev-dev libasound2-dev libdbus-1-dev
You also need the VideoCore binary stuff that ships in /opt/vc for EGL and
OpenGL ES 2.x, it usually comes pre installed, but in any case:
sudo apt-get install libraspberrypi0 libraspberrypi-bin libraspberrypi-dev
================================================================================
Cross compiling from x86 Linux
================================================================================
To cross compile SDL for Raspbian from your desktop machine, you'll need a
Raspbian system root and the cross compilation tools. We'll assume these tools
will be placed in /opt/rpi-tools
sudo git clone --depth 1 https://github.com/raspberrypi/tools /opt/rpi-tools
You'll also need a Rasbian binary image.
Get it from: http://downloads.raspberrypi.org/raspbian_latest
After unzipping, you'll get file with a name like: <date>-wheezy-raspbian.img
Let's assume the sysroot will be built in /opt/rpi-sysroot.
export SYSROOT=/opt/rpi-sysroot
sudo kpartx -a -v <path_to_raspbian_image>.img
sudo mount -o loop /dev/mapper/loop0p2 /mnt
sudo cp -r /mnt $SYSROOT
sudo apt-get install qemu binfmt-support qemu-user-static
sudo cp /usr/bin/qemu-arm-static $SYSROOT/usr/bin
sudo mount --bind /dev $SYSROOT/dev
sudo mount --bind /proc $SYSROOT/proc
sudo mount --bind /sys $SYSROOT/sys
Now, before chrooting into the ARM sysroot, you'll need to apply a workaround,
edit $SYSROOT/etc/ld.so.preload and comment out all lines in it.
sudo chroot $SYSROOT
apt-get install libudev-dev libasound2-dev libdbus-1-dev libraspberrypi0 libraspberrypi-bin libraspberrypi-dev libx11-dev libxext-dev libxrandr-dev libxcursor-dev libxi-dev libxinerama-dev libxxf86vm-dev libxss-dev
exit
sudo umount $SYSROOT/dev
sudo umount $SYSROOT/proc
sudo umount $SYSROOT/sys
sudo umount /mnt
There's one more fix required, as the libdl.so symlink uses an absolute path
which doesn't quite work in our setup.
sudo rm -rf $SYSROOT/usr/lib/arm-linux-gnueabihf/libdl.so
sudo ln -s ../../../lib/arm-linux-gnueabihf/libdl.so.2 $SYSROOT/usr/lib/arm-linux-gnueabihf/libdl.so
The final step is compiling SDL itself.
export CC="/opt/rpi-tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf-gcc --sysroot=$SYSROOT -I$SYSROOT/opt/vc/include -I$SYSROOT/usr/include -I$SYSROOT/opt/vc/include/interface/vcos/pthreads -I$SYSROOT/opt/vc/include/interface/vmcs_host/linux"
cd <SDL SOURCE>
mkdir -p build;cd build
LDFLAGS="-L$SYSROOT/opt/vc/lib" ../configure --with-sysroot=$SYSROOT --host=arm-raspberry-linux-gnueabihf --prefix=$PWD/rpi-sdl2-installed --disable-pulseaudio --disable-esd
make
make install
To be able to deploy this to /usr/local in the Raspbian system you need to fix up a few paths:
perl -w -pi -e "s#$PWD/rpi-sdl2-installed#/usr/local#g;" ./rpi-sdl2-installed/lib/libSDL2.la ./rpi-sdl2-installed/lib/pkgconfig/sdl2.pc ./rpi-sdl2-installed/bin/sdl2-config
================================================================================
Apps don't work or poor video/audio performance
================================================================================
If you get sound problems, buffer underruns, etc, run "sudo rpi-update" to
update the RPi's firmware. Note that doing so will fix these problems, but it
will also render the CMA - Dynamic Memory Split functionality useless.
Also, by default the Raspbian distro configures the GPU RAM at 64MB, this is too
low in general, specially if a 1080p TV is hooked up.
See here how to configure this setting: http://elinux.org/RPiconfig
Using a fixed gpu_mem=128 is the best option (specially if you updated the
firmware, using CMA probably won't work, at least it's the current case).
================================================================================
No input
================================================================================
Make sure you belong to the "input" group.
sudo usermod -aG input `whoami`
================================================================================
No HDMI Audio
================================================================================
If you notice that ALSA works but there's no audio over HDMI, try adding:
hdmi_drive=2
to your config.txt file and reboot.
Reference: http://www.raspberrypi.org/phpBB3/viewtopic.php?t=5062
================================================================================
Text Input API support
================================================================================
The Text Input API is supported, with translation of scan codes done via the
kernel symbol tables. For this to work, SDL needs access to a valid console.
If you notice there's no SDL_TEXTINPUT message being emitted, double check that
your app has read access to one of the following:
* /proc/self/fd/0
* /dev/tty
* /dev/tty[0...6]
* /dev/vc/0
* /dev/console
This is usually not a problem if you run from the physical terminal (as opposed
to running from a pseudo terminal, such as via SSH). If running from a PTS, a
quick workaround is to run your app as root or add yourself to the tty group,
then re login to the system.
sudo usermod -aG tty `whoami`
The keyboard layout used by SDL is the same as the one the kernel uses.
To configure the layout on Raspbian:
sudo dpkg-reconfigure keyboard-configuration
To configure the locale, which controls which keys are interpreted as letters,
this determining the CAPS LOCK behavior:
sudo dpkg-reconfigure locales
================================================================================
OpenGL problems
================================================================================
If you have desktop OpenGL headers installed at build time in your RPi or cross
compilation environment, support for it will be built in. However, the chipset
does not actually have support for it, which causes issues in certain SDL apps
since the presence of OpenGL support supersedes the ES/ES2 variants.
The workaround is to disable OpenGL at configuration time:
./configure --disable-video-opengl
Or if the application uses the Render functions, you can use the SDL_RENDER_DRIVER
environment variable:
export SDL_RENDER_DRIVER=opengles2
================================================================================
Notes
================================================================================
* When launching apps remotely (via SSH), SDL can prevent local keystrokes from
leaking into the console only if it has root privileges. Launching apps locally
does not suffer from this issue.

Touch
===========================================================================
System Specific Notes
===========================================================================
Linux:
The linux touch system is currently based off event streams, and proc/bus/devices. The active user must be given permissions to read /dev/input/TOUCHDEVICE, where TOUCHDEVICE is the event stream for your device. Currently only Wacom tablets are supported. If you have an unsupported tablet contact me at jim.tla+sdl_touch@gmail.com and I will help you get support for it.
Mac:
The Mac and iPhone APIs are pretty. If your touch device supports them then you'll be fine. If it doesn't, then there isn't much we can do.
iPhone:
Works out of box.
Windows:
Unfortunately there is no windows support as of yet. Support for Windows 7 is planned, but we currently have no way to test. If you have a Windows 7 WM_TOUCH supported device, and are willing to help test please contact me at jim.tla+sdl_touch@gmail.com
===========================================================================
Events
===========================================================================
SDL_FINGERDOWN:
Sent when a finger (or stylus) is placed on a touch device.
Fields:
* event.tfinger.touchId - the Id of the touch device.
* event.tfinger.fingerId - the Id of the finger which just went down.
* event.tfinger.x - the x coordinate of the touch (0..1)
* event.tfinger.y - the y coordinate of the touch (0..1)
* event.tfinger.pressure - the pressure of the touch (0..1)
SDL_FINGERMOTION:
Sent when a finger (or stylus) is moved on the touch device.
Fields:
Same as SDL_FINGERDOWN but with additional:
* event.tfinger.dx - change in x coordinate during this motion event.
* event.tfinger.dy - change in y coordinate during this motion event.
SDL_FINGERUP:
Sent when a finger (or stylus) is lifted from the touch device.
Fields:
Same as SDL_FINGERDOWN.
===========================================================================
Functions
===========================================================================
SDL provides the ability to access the underlying Finger structures.
These structures should _never_ be modified.
The following functions are included from SDL_touch.h
To get a SDL_TouchID call SDL_GetTouchDevice(index).
This returns a SDL_TouchID.
IMPORTANT: If the touch has been removed, or there is no touch with the given ID, SDL_GetTouchID will return 0. Be sure to check for this!
The number of touch devices can be queried with SDL_GetNumTouchDevices().
A SDL_TouchID may be used to get pointers to SDL_Finger.
SDL_GetNumTouchFingers(touchID) may be used to get the number of fingers currently down on the device.
The most common reason to access SDL_Finger is to query the fingers outside the event. In most cases accessing the fingers is using the event. This would be accomplished by code like the following:
float x = event.tfinger.x;
float y = event.tfinger.y;
To get a SDL_Finger, call SDL_GetTouchFinger(touchID,index), where touchID is a SDL_TouchID, and index is the requested finger.
This returns a SDL_Finger*, or NULL if the finger does not exist, or has been removed.
A SDL_Finger is guaranteed to be persistent for the duration of a touch, but it will be de-allocated as soon as the finger is removed. This occurs when the SDL_FINGERUP event is _added_ to the event queue, and thus _before_ the SDL_FINGERUP event is polled.
As a result, be very careful to check for NULL return values.
A SDL_Finger has the following fields:
* x,y,pressure:
The current coordinates of the touch.
* pressure:
The pressure of the touch.

A SDL_Finger is guaranteed to be persistent for the duration of a touch, but it will be de-allocated as soon as the finger is removed. This occurs when the SDL_FINGERUP event is _added_ to the event queue, and thus _before_ the SDL_FINGERUP event is polled.
As a result, be very careful to check for NULL return values.
A SDL_Finger has the following fields:
* x, y:
The current coordinates of the touch.
* pressure:
The pressure of the touch.

### 5. Add a WinRT-appropriate main function, and a blank-cursor image, to the app. ###
C/C++-based WinRT apps do contain a `main` function that the OS will invoke when
the app starts launching. The parameters of WinRT main functions are different
than those found on other platforms, Win32 included. SDL/WinRT provides a
platform-appropriate main function that will perform these actions, setup key
portions of the app, then invoke a classic, C/C++-style main function (that take
in "argc" and "argv" parameters). The code for this file is contained inside
SDL's source distribution, under `src/main/winrt/SDL_winrt_main_NonXAML.cpp`.
You'll need to add this file, or a copy of it, to your app's project, and make
sure it gets compiled using a Microsoft-specific set of C++ extensions called
C++/CX.
A few files should be included directly in your app's MSVC project, specifically:
1. a WinRT-appropriate main function (which is different than main() functions on
other platforms)
2. a Win32-style cursor resource, used by SDL_ShowCursor() to hide the mouse cursor
(if and when the app needs to do so). *If this cursor resource is not
included, mouse-position reporting may fail if and when the cursor is
hidden, due to possible bugs/design-oddities in Windows itself.*
**NOTE: C++/CX compilation is currently required in at least one file of your
app's project. This is to make sure that Visual C++'s linker builds a 'Windows
Metadata' file (.winmd) for your app. Not doing so can lead to build errors.**

To include these files:
1. right-click on your project (again, in Visual C++'s Solution Explorer),
navigate to "Add", then choose "Existing Item...".
2. open `SDL_winrt_main_NonXAML.cpp`, which is found inside SDL's source
distribution, under `src/main/winrt/`. Make sure that the open-file dialog
closes, either by double-clicking on the file, or single-clicking on it and
then clicking Add.
3. right-click on the file (as listed in your project), then click on

#### Mouse-motion events fail to get sent, or SDL_GetMouseState() fails to return updated values
This may be caused by a bug in Windows itself, whereby hiding the mouse
cursor can cause mouse-position reporting to fail.
SDL provides a workaround for this, but it requires that an app links to a
set of Win32-style cursor image-resource files. A copy of suitable resource
files can be found in `src/main/winrt/`. Adding them to an app's Visual C++
project file should be sufficient to get the app to use them.
#### SDL's Visual Studio project file fails to open, with message, "The system can't find the file specified."
This can be caused for any one of a few reasons, which Visual Studio can
report, but won't always do so in an up-front manner.
To help determine why this error comes up:
1. open a copy of Visual Studio without opening a project file. This can be
accomplished via Windows' Start Menu, among other means.
2. show Visual Studio's Output window. This can be done by going to VS'
menu bar, then to View, and then to Output.
3. try opening the SDL project file directly by going to VS' menu bar, then
to File, then to Open, then to Project/Solution. When a File-Open dialog
appears, open the SDL project (such as the one in SDL's source code, in its
directory, VisualC-WinRT/UWP_VS2015/).
4. after attempting to open SDL's Visual Studio project file, additional error
information will be output to the Output window.
If Visual Studio reports (via its Output window) that the project:
"could not be loaded because it's missing install components. To fix this launch Visual Studio setup with the following selections:
Microsoft.VisualStudio.ComponentGroup.UWP.VC"
... then you will need to re-launch Visual Studio's installer, and make sure that
the workflow for "Universal Windows Platform development" is checked, and that its
optional component, "C++ Universal Windows Platform tools" is also checked. While
you are there, if you are planning on targeting UWP / Windows 10, also make sure
that you check the optional component, "Windows 10 SDK (10.0.10240.0)". After
making sure these items are checked as-appropriate, install them.
Once you install these components, try re-launching Visual Studio, and re-opening
the SDL project file. If you still get the error dialog, try using the Output
window, again, seeing what Visual Studio says about it.
#### Game controllers / joysticks aren't working!
Windows only permits certain game controllers and joysticks to work within
WinRT / UWP apps. Even if a game controller or joystick works in a Win32
app, that device is not guaranteed to work inside a WinRT / UWP app.
According to Microsoft, "Xbox compatible controllers" should work inside
UWP apps, potentially with more working in the future. This includes, but
may not be limited to, Microsoft-made Xbox controllers and USB adapters.
