How can I compile OpenFoam with a custom MPI implementation? – CentOS

I am trying to install OpenFoam-19.06 in a CentOS 6.6
I have a MPI version in /global/mpi/mympich.
In the file etc/bashrc I’ve created the variable:

export WM_MPLIB=MYMPICH

>
and in the file etc/config.sh/mpi I’ve created a new case:

MYMPICH)
    export FOAM_MPI=mympich
    export MPI_ARCH_PATH=/global/mpi/mympich
    export MPICH_PATH=$MPI_ARCH_PATH

    _foamAddPath    $MPI_ARCH_PATH/bin
    _foamAddLib     $MPI_ARCH_PATH/lib
    ;;

Then I set the environment variables with:

source etc/bashrc

and compile the third party software with (in the appropriate directory):

./makeCGAL

Finally, I compile OpenFoam with (in the appropriate directory):

./Allwmake

It seems to start well:

========================================
2019-11-15 13:24:03 +0100
Starting compile OpenFOAM-v1906 Allwmake
  Gcc system compiler
  linux64GccDPInt32Opt, with MYMPICH mympich
========================================

built wmake-bin (linux64Gcc)

========================================
Start ThirdParty Allwmake
========================================
using:  gcc -m64 -DOPENFOAM=1906 -DWM_DP -DWM_LABEL_SIZE=32 -Wall -O3 -fPIC
using:  g++ -std=c++11 -m64 -DOPENFOAM=1906 -DWM_DP -DWM_LABEL_SIZE=32 -Wall -Wextra -Wold-style-cast -Wnon-virtual-dtor -Wno-unused-parameter -Wno-invalid-offsetof -Wno-attributes -Wno-unknown-pragmas -O3 -DNoRepository -ftemplate-depth-100 -fPIC

========================================
Build MPI libraries if required
    /global/mpi/mympich

But it ends With the following result:

module.h:236:37: warning: ‘foldval’ may be used uninitialized in this function [-Wmaybe-uninitialized]
 #define SCOTCH_NAME_PREFIX_INTERN   _SCOTCH
                                     ^

So far, I haven’t found a good guide to do what I’m targeting.

    In OpenFOAM-1712 and later, there is provision for just what you want. It’s called USERMPI. If you specify this, it will look for a corresponding mplib rule, which you also are in charge of creating.

    Probably best to raise as a documentation issue/query on their gitlab tracker.

    If you want to see a really detailed example, take a look at the spack openfoam/package.py – there it is populated by values from spack

    no, I think you have installed mpich? or something else. We don’t have a mpi named "mympi".
