Hello everyone,

I am currently working on compiling the source of openFoam. I am using the latest version of openFoam. I am also following the instructions outlined in the following webpost:

www.openfoam.com/download/install-source.php.

When I execute the following command:

source ~/OpenFOAM/OpenFOAM-v1606+/etc/bashrc

I receive the following error message:

cc: error: unrecognized command line option '--showme:link'

I am not sure what could be causing the issue. I have installed OpenFOAM on a number of different machines and this is my first time running into the issue.

Would anyone have any idea on how I can solve this?

Quick answer: The problem is that "bashrc" is configured to use the system's Open-MPI installation by default, not MPICH (from what I can see from this thread of yours: http://www.cfd-online.com/Forums/lou...h-cluster.html).

There are a few possible solutions, depending on how exactly you installed MPICH. The simplest is to do the following steps:

1. Edit the file "~/OpenFOAM/OpenFOAM-v1606+/etc/bashrc".
2. Find this line:
   

   export WM_MPLIB=SYSTEMOPENMPI

3. Change it to this:
   

   export WM_MPLIB=MPICH

4. Save and close this file.
5. Now edit the file "~/OpenFOAM/OpenFOAM-v1606+/etc/config.sh/mpi".
6. Find this line:
   

   MPICH)

7. Update the settings below that line according to the installation that you have of MPICH.
8. Save and close this file.
9. Run:
   

   source ~/OpenFOAM/OpenFOAM-v1606+/etc/bashrc

   and try again.
