Emscripten
|
|
================================================================================
|
|
|
|
SDL currently requires at least Emscripten 2.0.32 to build. Newer versions
|
|
are likely to work, as well.
|
|
|
|
|
|
Build:
|
|
|
|
$ mkdir build
|
|
$ cd build
|
|
$ emconfigure ../configure --host=asmjs-unknown-emscripten --disable-assembly --disable-threads --disable-cpuinfo CFLAGS="-O2"
|
|
$ emmake make
|
|
|
|
Or with cmake:
|
|
|
|
$ mkdir build
|
|
$ cd build
|
|
$ emcmake cmake ..
|
|
$ emmake 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
|
|
|
|
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
|
|
build as usual...
