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??!
