Julien, the fortran lib is in /usr/lib/libmpi_mpifh.so.12 the C lib is the one from Intel MPI
i guess the C lib is in /usr/lib, and not /usr/lib/openmpi/lib prepending /usr/lib is never recommended, so i suggest you simply remove /opt/intel/compilers_and_libraries_2016.1.150/linux/mpi/intel64/lib from your LD_LIBRARY_PATH Cheers, Gilles On Tue, Nov 15, 2016 at 10:33 PM, Julien de Troullioud de Lanversin <j.detroulli...@gmail.com> wrote: > Gilles, > > > Thank you for your fast reply. > > When I type whereis mpifort I have the following: mpifort: > /usr/bin/mpifort.openmpi /usr/bin/mpifort /usr/share/man/man1/mpifort.1.gz > > I made sure I exported the LD_LIBRARY_PATH after I prepended > /usr/lib/openmpi/lib.
