I use f2py to compile the file barotropic.f90 from the module 'model2roms' (https://github.com/trondkr/model2roms). My installations are: macOS Monterey 12.5 Xcode 13.4.1 Python 3.9.13 When I run: f2py -c -m barotropic barotropic.f90       Then the log shows: Log The problem seems to be in this line: ld: unsupported tapi file type '!tapi-tbd' in YAML file '/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/lib/libSystem.tbd' for architecture x86_64 I think it is weird that I run macOS 12.5, but f2py refers to 'src.macosx-10.9-x86_64-3.9' Does anyone know why I get this error and how I can solve it? I already tried: $ brew upgrade llvm $ brew upgrade gcc $ sudo rm -rf /Library/Developer/CommandLineTools $ xcode-select --install And I tried to downgrade Xcode to an older version
