| ================================================================================ |
| |
| 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 |
| build as usual... |
