[MITgcm-support] make problems

[Gus Correa]

Hi Nataliya

My guess is that you are missing some libraries required by MPICH2.

It tends to be simpler to use mpif77 or mpif90, perhaps with full path,
instead of ifort (*if* your MPICH2 was compiled with ifort).
The mpi compiler wrapper knows where to look for its libraries.

FC=ifort -> FC=/full/path/to/mpich/mpif77

An alternative is to do:

mpif77 -show

to see which additional flags you need to add to FFLAGS or LDFLAGS.

My two cents,
Gus Correa
