[OpenFOAM.org] gcc: error: unrecognized command line option '--showme:link'

mbcx4jc2 · February 9, 2015, 10:14

I'm running Ubuntu 14.04 LTS 64-bit. Having followed the instructions on the Ubuntu Deb Pack Installation, I came across the error:

Code:

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

However, doing

Code:

sudo update-alternatives --list mpi

Give

Code:

/usr/lib/openmpi/include

instead of what the instructions suggest is the cause of the problem (i.e. that the output should be /usr/mpich/include if MPICH is installed).

Doing

Code:

sudo update-alternatives --set mpi /usr/lib/openmpi/include

Obviously achieves nothing as it's already correctly set.

Doing

Code:

which mpicc

gives a clue:

Code:

~/anaconda/bin/mpicc

which suggests that my installation of anaconda is causing some conflicts.

Any ideas? Many thanks!

Hi,

It seems Anaconda uses MPICH2 instead of OpenMPI. So, you can try following this thread: http://www.cfd-online.com/Forums/ope...me-errors.html.

Thanks for the reply.

For anyone stumbling on this problem, I followed the instructions in the link supplied above which involved putting a file called "pref.sh" in /opt/openfoam231/etc/ which contains the line:

Quote:

export WM_MPLIB=OPENMPI

This solved the problem.
