Dear Foamers,

I've been trying to install OF-2.0.x on a cluster running MVAPICH2.

Somehow, the install script is unable to properly locate or use the pre-installed MPI.

I get errors such as

ptscotchDecomp.C(125): catastrophic error: cannot open source file "mpi.h"

despite having set

#- MPI implementation:
#    WM_MPLIB = SYSTEMOPENMPI | OPENMPI | MPICH | MPICH-GM | HPMPI
#               | GAMMA | MPI | QSMPI
export WM_MPLIB=MVAPICH2

in the bashrc file and having added

case "$WM_MPLIB" in
MVAPICH2)
export MPI_HOME=/sw/comm/mvapich2/1.5.0-gcc
export MPI_ARCH_PATH=$MPI_HOME
_foamAddPath $MPI_ARCH_PATH/bin
_foamAddLib $MPI_ARCH_PATH/lib
export FOAM_MPI_LIBBIN=$FOAM_LIBBIN/MVAPICH2
;;

in settings.sh.

I have also checked to see that the file mpi.h actually exists

ls $MPI_ARCH_PATH/include
mpi_base.mod       mpicxx.h  mpi.h    mpiof.h  mpi_sizeofs.mod  opa_primitives.h  opa_util.h
mpi_constants.mod  mpif.h    mpi.mod  mpio.h   opa_config.h     opa_queue.h       primitives

and also opened it in an editor just to be sure.

I have also tried calling my MPI implementation MPI-MVAPICH2 since I have heard that some scripts check for the presence of MPI in the name. If I do this I get the same errors about not being able to find mpi.h, however, I get these much sooner when building PStream and scotch rather early on. I have also tried both gcc and Icc with similar results.

I don't quite understand why the install script cannot find the neccessary files. Does anybody have any ideas?
