[Trilinos-Users] Error compiling pamgen: MPI_LONG_LONG_INT undefined

As the title of the email says, I'm having an error compiling pamgen,
because MPI_LONG_LONG_INT is not defined. The cluster I'm using has an
installation of openmpi which does not define MPI_LONG_LONG_INT (I checked
the mpi.h file on the cluster).

According to the link below, MPI_LONG_LONG_INT may not be implemented on
some systems.


If this is true, and assuming my cluster maintenance people cannot/don't
want to change the mpi installation, how can I circumvent this? The file
that uses MPI_LONG_LONG_INT does not appear to encapsule it inside any
preprocessor guard, to check the existence of MPI_LONG_LONG_INT.

Thanks for your help!
