Hi,
You probably need to specify the SDK location. There are a number ways you can
do this, gcc now supports the same mechanisms as clang. i.e. using scrub or
setting SDKROOT .
I personally have
export SDKROOT=`xcrun --show-sdk-path`
in my shell profile for this very reason.

Thank you Marius,
it did not help. I also reboot the machine.
Now I am getting:
ld: library not found for -lm
collect2: error: ld returned 1 exit status
I am not sure whether the message from collect2 was there before running
sudo port select gcc mp-gcc-devel.
I am using bash, but in default
Petr,
sudo port select gcc mp-gcc-devel
will add links so that the binaries, includes and libraries can be found.

Thank you Chris,
I found gfortran-mp-devel in /opt/local/bin.
However trying to compile my source a got linker error:
ld: library not found for -lm
And I am lost again. I did not specified any linker options,
just compiler options:
-g -fbounds-check -ffpe-trap=invalid,zero,overflow
Hi,
Gcc-devel provides gfortran for M1 machines by default.

Is it already possible to install gfortran on M1?
It seems that gcc-devel does not have +gfortran variant and and other gcc
versions are not compatible.
Thank you,
