Error Code% ld: library not found for -lSystem

Hello, I have installed XCode and the final release of g77 Fortran complier.

This worked perfectly on my previous MacBook. When I re-installed these applications on my new MacBook (Catalina) Ik get the mentioned error system when running the gfortran application in Terminal.

R, Marc
How did you reinstall ? Did you reload from Mac Appstore ?

Maybe trying to use an older version of XCode could help ?
