emscripten support? #520

Open julhe opened 1 year ago

julhe commented 1 year ago

Currently, building for emscripten fails with:

/SourceExternal/EASTL/test/packages/EABase/include/Common\EABase/config/eaplatform.h:623:3: error: Unknown platform
        #error Unknown platform
         ^
/SourceExternal/EASTL/test/packages/EABase/include/Common\EABase/config/eaplatform.h:624:3: error: Unknown processor
        #error Unknown processor
         ^
/SourceExternal/EASTL/test/packages/EABase/include/Common\EABase/config/eaplatform.h:625:3: error: Unknown endianness
        #error Unknown endianness

Is support ever planed or is it ouside the scope of this project?

Hi. No, this isn't planned for EABase or EASTL.

I think it basically supports it as is (no real testing done, but it compiles and tuple-vector worked fine). I just added the following to eaplatform.h
