build successfully on macOS monterey but can't find old llvm@12 dylib #107

Open Inc0n opened 2 years ago

Inc0n commented 2 years ago

Build was successful using the script copied from https://github.com/rpav/c2ffi/issues/104#issuecomment-1038468510, with the only difference that llvm@13 is installed, and all environmental variables are changed accordingly.

However, when running c2ffi, it produced the following error:

dyld[11622]: Library not loaded: /opt/homebrew/opt/llvm@12/lib/libclang-cpp.dylib
  Referenced from: /Users/xception/.local/bin/c2ffi
  Reason: tried: '/opt/homebrew/opt/llvm@12/lib/libclang-cpp.dylib' (no such file), '/usr/local/lib/libclang-cpp.dylib' (no such file), '/usr/lib/libclang-cpp.dylib' (no such file)
zsh: abort      c2ffi

It's trying to find llvm@12, whilst the configured llvm is versioned 13.

The actual build script used ``` mkdir -p build cd build export CPPFLAGS="-I/opt/homebrew/opt/llvm@13/include" export LDFLAGS="-L/opt/homebrew/opt/llvm@13/lib" export PATH="/opt/homebrew/opt/llvm@13/bin:$PATH" LLVM_DIR=/opt/homebrew/opt/llvm@13/ CC="clang" CXX="clang++" cmake --install-prefix ~/.local/bin .. make make install ```

On my macOS Monterey 12.4 with M1 I get the following error with your script
