How to apply it in WebAssembly? about demucs.cpp HOT 11 CLOSED

Take a look at this: https://github.com/sevagh/demucs.cpp/tree/wasm/src_wasm

It gives some hints (not all) of how to make a functioning website similar to freemusicdemixer.com

from demucs.cpp.

I'll work on adding more obvious WebAssembly pieces to this repo.

The instructions are very clear. I was able to compile demucs.js and demucs.wasm correctly on MacOS. If it can be helpful to anyone else, I deviated from the instructions and installed emscripten on MacOS via brew install emscripten.

I'll try running the compiled files in the browser later, but I understand the required steps.

Thanks for the help and for your efforts in this amazing project 🙌🏻

Thank you very much

From https://github.com/sevagh/freemusicdemixer.com 's docs it seems the library is supposed to be compiled using emscripten. I gave it a shot but I wasn't able to compile it, but I'm not really familiar with this ecosystem.

Adding instructions to the README would be very appreciated 🙂

@illbexyz @sevagh Sorry to bother you, I always get the following error when trying wasm files. Can you all compile normally? Do I need to do anything extra?

/root/emsdk/upstream/lib/clang/19/include/mmintrin.h:14:2: error: "This header is only meant to be used on x86 and x64 architecture"
   14 | #error "This header is only meant to be used on x86 and x64 architecture"

This command worked for me:

rm -rf build-wasm && mkdir -p build-wasm && cd build-wasm \
  && emcmake cmake -DCMAKE_BUILD_TYPE=Release \
  ../src_wasm && make -j16'

@illbexyz Okay, I used the same command as you, but it didn't work... My system is M1 Max. I'm not sure if this has anything to do with the operating system.

Are you sure you are using emcmake cmake and not plain cmake?

Yes, I am sure that I executed it with the following command.

rm -rf build-wasm && mkdir -p build-wasm && cd build-wasm \
  && emcmake cmake -DCMAKE_BUILD_TYPE=Release \
  ../src_wasm && make -j16

I think it's OK to keep this issue closed. I think Mac/OSX problems with the Emscripten/WASM toolchain is out of the scope of demucs.cpp
