Compilation error with mpifort gcc

CMAQ Compiling
1

Dear all,

When compiling with the version v5.4 we found syntax errors in the code.

Compiler version
$ mpifort --version
GNU Fortran (Debian 10.2.1-6) 10.2.1 20210110

These are Fortran-language errors, that require recoding.

Most of them seem related to MPI, are we missing any flag?

Thanks,

The above says that your mpifort is based on gfortran version 10.2.1

See the I/O API Makeinclude.Linux2_x86_64gfort10 – starting with version 10, gfortran has its own idiosyncratic interpretation of the Fortran Standard. You probably need to add the compile-flag

-fallow-argument-mismatch

to your CMAQ compile-flags, as the I/O API does for its gfortran-10 flags…

Don’t you just love the way some compiler-writers don’t preserve version-to-version compatibility??!

Thank you so much for your quick answer!

That worked perfectly.
