- Install LLVM Clang:
brew install llvm
- Add it to your PATH:
export PATH="/opt/homebrew/opt/llvm/bin:$PATH"
For future use, add it to your .zshrc file:
echo 'export PATH="/opt/homebrew/opt/llvm/bin:$PATH"' >> ~/.zshrc
Verify the installation:
llvm-config --version
You should see a version number, such as 20.1.3.
