如何在 Mac 上使用 gfortran 修复“ld:unexpected token:!tapi-tbd-v3 file”？

Question

I keep getting this error whenever I try and compile a .f90 file on my Mac Mojave (10.14)

collect2: fatal error: ld terminated with signal 11 [Segmentation fault: 11] compilation terminated. ld: unexpected token: !tapi-tbd-v3 file '/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/lib/libSystem.tbd' for architecture x86_64

I've tried uninstalling Xcode and command line tools multiple times as well as created a symlink to the *tbd file so it doesn't require the tbd files anymore. I've also tried deleting gfortran from my laptop and reinstalling it again but it's still not working.

I don't really know how to go about fixing this problem and I'm also a beginner at this compiler/linker topic. Any help would be greatly appreciated.

Answer 1

In case you installed gfortran via MacPorts, please uninstall it and install the xcode variant of the ld64 port:

sudo port install ld64 +ld64_xcode 

After this, install gcc (version N) with -s to build it on your local machine:

sudo port install libgcc<N> libgcc
sudo port install -s gcc<N>

Unfortunately, I'm not familiar with solutions not using MacPorts.

Answer 2

After installing macports, the below 2 commands worked for me

sudo port -f activate ld64
sudo port install ld64 +ld64_xcode
