I have installed the latest available gfortran package (together with Apple Developer Tools installed, as well as "command line developer tools") as described here:

https://gcc.gnu.org/wiki/GFortranBinariesMacOS

If I try to run a simple fortran code from terminal using:

gfortran test.f90 -o test

I get the following error:

ld: library not found for -lSystem
collect2: error: ld returned 1 exit status

I am running it on Catalina 10.15.7 and xCode version 12.0.1.

I have found a similar question that was solved by reinstalling xCode, but that did not help me. What do I need to do to get it working? I will be happy to add context/details to the question if it helps.

Thanks!

Edit

Instead of installing the gfortran package itself, I installed the whole gcc using homebrew:

brew install gcc

and that solved the problem.

We do need as much detail as possible. Otherwise it will end up like the many questions that asked the same before - without any answer. – Vladimir F Героям слава Oct 13 '20 at 19:06
Could you also add your solution as an answer to https://stackoverflow.com/questions/56156520/gfortran-error-ld-library-not-found-for-lsystem-when-trying-to-compile ? It would be most helpful. – Vladimir F Героям слава Oct 14 '20 at 10:49
