Hello,

I have installed gfortran package (together with Apple Developer Tools installed, as well as "command line developer tools").

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

gfortran test.f90 -o test

I get following error:

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

I tried to google for it but did not find anything helpful. What do I need to do to get it working?

Thanks!

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

brew install gcc

and that solved the problem.

SORRY!
I have same problem when I update my Mac to BIg Sur. When I run my Fortran program

Code Block ifort ***.f90

then I will get the error:

Code Block ld: library not found for -lSystem

I have find a way solve it by using the following format

Code Block  ifort ***.f90 -L/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/lib

but I want it to get normal, how should I do it? Changing the configuration envirament? how should I change? I'm a fresh man in MAC.
THANK YOU!
