clang++: error: unsupported option '-march=' / '-mfma' for target 'wasm32-unknown-emscripten' when executing make

[ttqftech]

I've follow the instructions in README to compile myself. But when I execute cmake in the last step, error occurs.
It happens both on two environments:

• Ubuntu on Windows Subsystem for Linux (22.04.3 LTS)
• macOS (14.3.1)

I'm a js developer and don't know much things about C/C++. Hope to solve this problem so that I can continue my little discovery :-)

I'm not sure I can figure out this clang error, but maybe as a workaround you can download the pre-compiled pitchlite.js and pitchlite.wasm files: https://github.com/sevagh/pitchlite/tree/main/web

✅I've founded the following solution:
Removing -march=native -mfma in CMAKE_CXX_FLAGS_RELEASE line.

I guess wasm32-unknown-emscripten is Emscripten's default unconfigurable target, and there is not something native in unknown architecture?

Glad to hear it! If you want to submit a fix, go ahead and I'll merge it.
