问题
So bear with me as I am very new to coding. I'm trying to compile a Fortran file but I keep getting this issue in my terminal. I am using GNU Fortran (GCC) 9.2.0 and I believe I have all other prerequisites updated Xcode and atom. Appreciate any and all help spent went way too long just to say hello world.
% gfortran -o myprog hello.f90
ld: library not found for -lSystem
collect2: error: ld returned 1 exit status
