How to compile oneTBB with Emscritpen?

[dpar39]

Is it possible to compile oneTBB with Emscripten? There are third party libraries using oneTBB and it would be nice to get them to compile without changing the source code.

I do not know if someone using oneTBB with Emscripten. Have you tried to build as is?

Issues related to assembling oneTBB with Emscripten can be divided into 2 category:

1. Build issue, related to undefined reference to `__TBB_machine_fetchadd4', has been fixed with Define ITT_ARCH_IA64 when undefined #550.
2. Compiler warnings.
   Emscripten compliler doesn't familiar with some flags used by oneTBB for x86/AMD64 processors. Those flags are ignored and marked as 'unused'. As a work-around, compile oneTBB with cmake flag 'TBB_STRICT' to 'OFF'
   emcmake cmake -DTBB_STRICT=OFF ..
