Hello,

I am trying to build the owl ocaml package for macOS and I am running into the following error message:

ld: file not found: @rpath/libgcc_s.1.1.dylib for architecture arm64

I have found the following files:

/Library/Developer/CommandLineTools/SDKs/MacOSX11.3.sdk/usr/lib/libgcc_s.1.tbd
/Library/Developer/CommandLineTools/SDKs/MacOSX12.1.sdk/usr/lib/libgcc_s.1.tbd
/Library/Developer/CommandLineTools/SDKs/MacOSX11.3.sdk/usr/lib/libgcc_s.1.tbd

Which seem to be referenced via -L/Library/Developer/CommandLineTools/SDKs/MacOSX/usr/lib

Though I have been unable to get ld to properly recognize the libgcc_s.1.tbd for the ld: file not found: @rpath/libgcc_s.1.1.dylib requirement.

How do we get ld to see libgcc_s.1.tbd?

Cheers, Joe

While I have not directly solved the issue, I have learned that libgcc_s is implicitly required due to OpenBLAS and LAPACK being built by gcc and gfortran. The libgcc is likely not needed, though I have not found where it is sneaking into the builds.

I did try to just statically link to the absolute path of the homebrew dylib and the provided .tbd file without success. There is a static lib which is for x86 and not arm64.
