Hi,
Note, using the test application at
https://gist.github.com/certik/9755084
On my macOS 10.15 Xcode 11.1 machine here works just fine. See below.
I suspect your issue is the SDK path baked into the compiler you are
using does not match what is now available on your system. You should
check the output you get from the -v compilation and compare to what is
actually available.
cheers Chris

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
