[MITgcm-support] Problem with parallel build

[Gustavo Correa]

Hi Chun-Yan, Martin

I think the macros MPI_INC_DIR, MPI_HEADER_FILES_INC, probably should point to
a *directory*, not to a file.
However, on my admittedly old build options files I don't have these macros.
I have the "INCLUDES" macro which is again points to the MPI include *directory*, not to a file:
INCLUDES=/path/to/mpi/include

I don't think there is any mpiof.h file in MPI either.
It sounds as some typo.
I would just remove it from the options file and see how it goes.

In addition, I second Martin's suggestion 
that you use the FC=mpif77 or FC=mpif90 compiler wrapper,
instead of the compiler itself (ifort, gfortran, whatever). 
The compiler wrapper will be able to find the include files.

I hope this helps,
Gus Correa

Yes, I found the mpif77 in the path '/usr/lib64/openmpi/bin/' and the mpif.h in the path  '/usr/include/openmpi-x86_64/', but still can't find the mpiof.h and the the administer told me that he don't (yet) know which package mpiof.h belongs to - could you confirm this is the correct filename?
