Is there any way to compile a C project by WASM? #129

Closed lichaozhy closed 3 years ago

lichaozhy commented 3 years ago

I am a web front-end engineer. A project running in browser need KFR. So I have been trying some days to compile a "module.c" using KFR as a WASM module. But there a too many troubles.

The detail of wasm:

I'am working on win10 / MinGW64 / CMake / EMSCRIPTEN. What I want to know most at the moment is, can this be successful?

Some problems look about CPU-ARCH and SIMD,

WASM isn't supported at this moment but it may change in future.

Hi, I am facing the same problem, is there any update on the support of WASM?
