Hello!


I am trying to install with mpich3.2 in CentOS7. I made couple of changes in the root folder.




In etc/bashrc, I have changed the following

export WM_MPLIB=MPICH

In etc/config.sh/mpi, I have changed the following

MPICH)
    export FOAM_MPI=mpich-3.2
    export MPI_ARCH_PATH=/home/D/mpich-3.2/install
    export MPI_HOME=$MPI_ARCH_PATH
    export FOAM_MPI_LIBBIN=$FOAM_LIBBIN/mpich-3.2

    # Could be sourced from ThirdParty with incomplete environment
    if command -v _foamAddLibAuto > /dev/null 2>&1  # Normal sourcing
    then
        _foamAddPath    $MPI_ARCH_PATH/bin
        _foamAddMan     $MPI_ARCH_PATH/share/man
        _foamAddLib $MPI_ARCH_PATH/lib
    fi
    ;;

But while compiling the code I get the following error in both V1812 and V1906

/home/D/foam/OpenFOAM-v1812/src/OpenFOAM/lnInclude/IOobject.H:497:14: note: because ‘Foam::IOobject’ has user-provided ‘void Foam::IOobject::operator=(const Foam::IOobject&)’

I would like to know if I need to change anything else apart from these values.



Thanks for your time.

Hmmm.. let's issue a ticket in the issue tracker in GitLab.

Any further information you can provide regarding your compilation?

[venkcy]

Thanks for the reply!


Let me know the information will be required and helpful to identify the error?



I have used GCC 9 and MPICH 3.2 for compilation.

I assume you've downloaded the mp* package into the ThirdParty dir?

I have run into the same problem but I have figured it out on Ubuntu 18.04. But I bet it will work on Centos 8 as well. Here is what I propose, you may want to install Openmpi alongside with the MPICH compiled from source. And once you got a way to switch back and forth, Problem solved! I suggest using "bash", which is a way to edit your ~/.bashrc or ~/.profile.

Add following lines to .bashrc

## switch between mpich and openmpi
use_mpi () {
shopt -s nocaematch
case "$1" in
mpich) export PATH=/home/to/your/MPICH/bin:$PATH
openmpi) export PATH=/usr/bin:$PATH ;;
*) return 1 ;;
esac
shopt -u nocasematch
}

After adding those lines, type
1. "source ~/.bashrc" to activate the commands;
2. "use_mpi mpich" will allow you to use mpich in the current terminal;
3. "use_mpi openmpi" will allow you to use openmpi.

Then you can handle different versions of MPI on your system (not limited to two, could be three, four, ..., etc) . I feel this is more elegant other than messing with OpenFoam source code before you are an advanced user.

Hope this will help you.

No! I built the package directly as I needed the newer version.


I was able to install OpenFOAM with IntelMPI.


Thanks for your concern!

Thanks for your help! Will try and get back to you.
