Hi,

mpif90 fails to build a simple executable on any arch other then amd64. For instance on arm64:

$ cat toto.f90 
PROGRAM FC_MPI_CHECK
  USE mpi
  INTEGER :: comm, amode, info, fh, ierror
  CHARACTER(LEN=1) :: filename
  CALL MPI_File_open( comm, filename, amode, info, fh, ierror)
END PROGRAM FC_MPI_CHECK

$ mpif90.openmpi -o toto toto.f90 
f951: Warning: Nonexistent include directory '/usr/lib/aarch64-linux-gnu/openmpi/lib/fortran/gfortran-mod-15/openmpi' [-Wmissing-include-dirs]
f951: Warning: Nonexistent include directory '/usr/lib/aarch64-linux-gnu/openmpi/lib/openmpi/lib' [-Wmissing-include-dirs]
toto.f90:2:7:

    2 |   USE mpi
      |       1
Fatal Error: Cannot open module file 'mpi.mod' for reading at (1): No such file or directory
compilation terminated.

S mpi.mod | grep openmpi
libopenmpi-dev:arm64: /usr/lib/aarch64-linux-gnu/fortran/gfortran-mod-15/openmpi/mpi.mod

Default include path seems broken.

Best,
_g.
