Chris, thanks a lot for your very quick answer!
1. I followed the path for migration and reinstalled all packages. I
will try to do it once more to be sure.
2. Xcode version: 11.0
3. My test program is minimum:
program test
print*,'a'
end program test
4. The output with -v option is:
Driving: gfortran test.f90 -v -mmacosx-version-min=10.15.0
-asm_macosx_version_min=10.15 -l gfortran -shared-libgcc
Using built-in specs.

can you please direct us to the exact test application code you are
using ?
Also, can you confirm the exact Xcode version you are using ?
Have you correctly followed the macports migration guide after
updating your OS ?

Hello,
I'm compiling with gfortran9 on catalina and get this error:
gfortran test.f90
ld: library not found for -lSystem
collect2: error: ld returned 1 exit status
Seems that it does not find the library libSystem. I changed all the
library paths in my bash_profile
to include /usr/lib but does not work. The only solution for the
moment is to compile with
gfortran test.f90-L/usr/lib
but this is not a practical option... Any idea on how to fix this?
Thanks in advance
