Using emscripten on M1 mac

[Amit Sharma]

Hi Folks - 

I am unable to compile a library using emscripten on M1 ARM mac. 

On my older mac (intel based), I didn't had any issues. 

The issue is around unresolved linker errors. 

The specific library that I am trying to compile here is openframeworks. 

Can anyone please point me on how to go about debugging or fixing this issue. 

I haven't used emscripten much except superficially using the documentation from the tutorials. 

error: undefined symbol: _ZN24ofxEmscriptenSoundStreamC1Ev (referenced by top-level compiled C/C++ code) warning: Link with `-s LLD_REPORT_UNDEFINED` to get more information on undefined symbols warning: To disable errors for undefined symbols use `-s ERROR_ON_UNDEFINED_SYMBOLS=0` warning: __ZN24ofxEmscriptenSoundStreamC1Ev may need to be added to EXPORTED_FUNCTIONS if it arrives from a system library error: undefined symbol: tessDeleteTess (referenced by top-level compiled C/C++ code) warning: _tessDeleteTess may need to be added to EXPORTED_FUNCTIONS if it arrives from a system library error: undefined symbol: tessNewTess (referenced by top-level compiled C/C++ code) warning: _tessNewTess may need to be added to EXPORTED_FUNCTIONS if it arrives from a system library Error: Aborting compilation due to previous error

Many thanks

Hi Shlomi - 

Please ignore the previous error. The make configuration was trying to build an executable instead of library.

But I am facing a new error. Seems something is broken 

 I was suggested by the project maintainer to use sdk-1.40.0-64bit. Like so:

./emsdk install sdk-1.40.0-64bit

However, this fails on M1 mac due to missing file error

Error: Downloading URL 'https://storage.googleapis.com/webassembly/emscripten-releases-builds/mac/4ba921c8c8fe2e8cae071ca9889d5c27f5debd87/wasm-binaries-arm64.tbz2': HTTP Error 404: Not Found error: installation failed!

Wondering how to go about fixing this error. 

thank you 

Am
