Jeff, Thanks for pointing me in the right direction. I have finally figured out what the problem is.
On the cluster we install Slurm via RPMs and the PMI/PMI2 libraries are in /usr/lib64. Hence the -L/usr/lib64 flag is the effect of the --with-pmi=/usr configure flag. The good thing is that even by omitting it the final binary is correctly linked to the PMI libraries. And the reason why in the other system I tested the build it was working is because there is no Slurm installed in it. -- Davide Vanzo, PhD Application Developer Adjunct Assistant Professor of Chemical and Biomolecular Engineering Advanced Computing Center for Research and Education (ACCRE) Vanderbilt University - Hill Center 201 (615)-875-9137 www.accre.vanderbilt.edu On 2017-11-29 16:07:04-06:00 Jeff Squyres (jsquyres) wrote: On Nov 29, 2017, at 4:51 PM, Vanzo, Davide <davide.va...@vanderbilt.edu> wrote: &gt; &gt; Although tempting, changing the version of OpenMPI would mean a significant amount of changes in our software stack. Understood. FWIW: the only differences between 1.10.3 and 1.10.7 were bug fixes (including, I'm assuming -- I haven't tested myself -- this -L issue).

Is there a way to patch the code so that it does not get added to the list of options to gfortran? It's injected pretty deep inside configure. We might be able to spelunk through the git logs to find the commit that fixes this issue and you could apply that as a patch, but it might be easier to just manually patch up the wrapper compiler data file after the build. Specifically, it looks like OMPI 1.10.3 is installing faulty values $prefix/share/openmpi/*-wrapper-data.txt. You can easily edit these files directly and remove the erroneous -L/usr/lib64. If you're unable to upgrade to 1.10.7, patching the installed *-wrapper-data.txt files is probably your best bet. -- Jeff Squyres jsquy...@cisco.com _______________________________________________ users mailing list users@lists.open-mpi.org https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Flists.open-mpi.org%2Fmailman%2Flistinfo%2Fusers&amp;data=02%7C01%7Cdavide.vanzo%40vanderbilt.edu%7C11f5b064a08144e0e4bc08d5377584eb%7Cba5a7f39e3be4ab3b45067fa80faecad%7C0%7C0%7C636475900235203296&amp;sdata=O94%2FKc7jajpw5%2BdCuRxvkjrdoR9ESR0DLB61C30%2BBp0%3D&amp;reserved=0 </davide.va...@vanderbilt.edu>
