Emscripten
================================================================================
Build:
$ emconfigure ./configure --host=asmjs-unknown-emscripten --disable-assembly --disable-threads --enable-cpuinfo=false CFLAGS="-O2"
$ emmake make
Or with cmake:
$ emconfigure cmake ..
$ make
To build one of the tests:
$ cd test/
$ emcc -O2 --js-opts 0 -g4 testdraw2.c -I../include ../build/.libs/libSDL2.a ../build/libSDL2_test.a -o a.html
Uses GLES2 renderer or software
tests: https://dl.dropboxusercontent.com/u/17360362/SDL2-em/index.html
Some other SDL2 libraries can be easily built (assuming SDL2 is installed somewhere):
SDL_mixer (http://www.libsdl.org/projects/SDL_mixer/)
$ EMCONFIGURE_JS=1 emconfigure ../configure
build as usual...
SDL_gfx (http://cms.ferzkopp.net/index.php/software/13-sdl-gfx):
$ EMCONFIGURE_JS=1 emconfigure ../configure --disable-mmx

Dollar Gestures
===========================================================================
SDL Provides an implementation of the $1 gesture recognition system. This allows for recording, saving, loading, and performing single stroke 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.

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 target platform!"

Add a section for your platform, and then re-run autogen.sh and build!

* keyboard input. Most of WinRT's documented virtual keys are supported, as
well as many keys with documented hardware scancodes.
* OpenGL. Experimental support for OpenGL ES 2 is available via the ANGLE
project, using either MS Open Technologies' repository, at
https://github.com/msopentech/angle (both the "winrt" and "future-dev"
branches are supported), or the official ANGLE repository, at

* MS Open Technologies' "angle-win8.0" repository, at https://github.com/MSOpenTech/angle-win8.0
(for Windows 8.0 only!)
* Google's main ANGLE repository, at https://chromium.googlesource.com/angle/angle
* SDLmain. WinRT uses a different signature for each app's main() function.
SDL-based apps that use this port must compile in SDL_winrt_main_NonXAML.cpp

supported by WinRT itself.
* joysticks and game controllers that aren't supported by Microsoft's XInput
API.
* turning off VSync when rendering on Windows Phone. Attempts to turn VSync
off on Windows Phone result either in Direct3D not drawing anything, or it
forcing VSync back on. As such, SDL_RENDERER_PRESENTVSYNC will always get
turned-on on Windows Phone. This limitation is not present in non-Phone
WinRT (such as Windows 8.x), where turning off VSync appears to work.
