Installing and running emscripten on OSX 10.15

Question

I recently installed emscripten on my macbook air using homebrew. But when I try to run it, even if i do a simple emcc --version i get the error llc executable not found at /usr/bin/llc. how can i fix this?

Answer 1

solution: llvm was not installed, so a brew install llvm followed by echo 'export PATH="/usr/local/opt/llvm/bin:$PATH"' >> ~/.zshrc solved this problem for me.

Answer 2

Hrm. Seems like adding brew install llvm, I'm still not able to call llvm on my end.

So i just installed brew install emscripten then I did emcc giving me

Welcome to Emscripten!

This is the first time any of the Emscripten tools has been run.

A settings file has been copied to /usr/local/Cellar/emscripten/1.39.18/libexec/.emscripten, at absolute path: /usr/local/Cellar/emscripten/1.39.18/libexec/.emscripten

It contains our best guesses for the important paths, which are:

  LLVM_ROOT       = /usr/bin
  NODE_JS         = /usr/local/bin/node
  EMSCRIPTEN_ROOT = /usr/local/Cellar/emscripten/1.39.18/libexec

Please edit the file if any of those are incorrect.

This command will now exit. When you are done editing those paths, re-run it.

Then i did emcc again, giving me BINARYEN_ROOT is set to empty value in /usr/local/Cellar/emscripten/1.39.18/libexec/.emscripten.

How did you set your BINARYEN_ROOT? i'm on the newest macos 10.15.5.
