Running make on wasm or wasm-ring-buffer returns Error #186

Closed cheesymoo closed 5 years ago

cheesymoo commented 5 years ago

When I try to build the wasm or wasm-ring-buffer using make I get the following error:

tools.shared.Py2CalledProcessError: Command '['/dev/emsdk/fastcomp/fastcomp/bin/llvm-ar', 'xo', '/.emscripten_cache/asmjs/libc++-noexcept.a']' returned non-zero exit status -9 make: *** [build] Error 1

Stack-trace:

I have installed emcc following its tutorial, and emcc -v successfully completes a sanity check. I can also build other simple wasm projects with emcc.

I'm going to attempt to get this working in a Docker image to remove any system specific concerns.

Any clue as to what might be going wrong here?

Thanks

I think this is actually related to this open issue on emscripten-core:

linker error #8819
