Emscripten Setup Support

[Mayur Pai]

Hi,

I am new to emscripten and got interested as we have a  complex C++ code that we want converted to Javascript.

I have installed emscripten on my laptop and have been able to verify the installation successfully by running emcc -v. However when I try to run the sample project, emscripten seems to be getting hanged consistently. Any recommendation on what might be happening and what I should try next?

C:\emsdk-master\fastcomp\emscripten\tests>emcc hello_world.cpp

cache:INFO: generating system library: libdlmalloc.bc... (this will be cached in "C:\Users\i718761\.emscripten_cache\asmjs\libdlmalloc.bc" for subsequent builds)

cache:INFO:  - ok

cache:INFO: generating system library: libpthreads_stub.bc... (this will be cached in "C:\Users\i718761\.emscripten_cache\asmjs\libpthreads_stub.bc" for subsequent builds)

cache:INFO:  - ok

cache:INFO: generating system library: libc.bc... (this will be cached in "C:\Users\i718761\.emscripten_cache\asmjs\libc.bc" for subsequent builds)

Regards,

Mayur Pai

It might take a while for libc.bc to build. I'd give it a night and check back the next day.

Building libc can be quite slow in windows for some reason, sorry about that. We are looking into it,
