[Question] build with emscripten

[MateusDornelles]

Hi, does sdl_gpu build with emscripten out of the box, or do i need to modify the build system ? I ask because when i tried to build it with emcmake it complained about not being able to find sdl2.

It builds out of the box, make sure you are passing the right compiler flags (eg: -s USE_SDL=2).

Is this a flag that should be added to the CMake script?

[albertvaka]

It's a bit more complicated than that, I've opened a PR with the needed changes to build on emscripten: #205

With those changes, the following build commands succeed:

mkdir build
cd build
emcmake cmake ..
emmake make

This should allow you to use sdl-gpu as a static library from your emscripten project, but note I haven't tested that. When I build sdl-gpu games on emscripten I copy the entire sdl-gpu project into my project and I build everything statically using the same compiler flags for all the code (sdl-gpu + my project code together). But I assume it should work as a static library as well :)
