Charles, have you tried to configure --with-pmix-libdir=/.../lib64 ?
Cheers, Gilles ----- Original Message ----- > I’ll add that when building OpenMPI 3.0.0 with an external PMIx, I found that the OpenMPI configure script only looks in “lib” for the the pmix library but the pmix configure/build uses “lib64” (as it should on a 64-bit system) so the configure script falls back to the internal PMIx. As Robert suggested, check your config.log for “not found” messages. > > In my case, I simply added a “lib -> lib64” symlink in the PMIx installation directory rather than alter the configure script and that did the trick. > > Good luck, > > Charlie > > > On Apr 23, 2018, at 6:07 PM, r...@open-mpi.org wrote: > > > > Hi Michael > > > > Looks like the problem is that you didn’t wind up with the external PMIx.

Also, ensure that your LD_LIBRARY_PATH is properly pointing to the installation, and that you built into a “clean” prefix. > > > > > >> On Apr 23, 2018, at 12:01 PM, Michael Di Domenico <mdidomenico4@ gmail.com> wrote: > >> > >> i'm trying to get slurm 17.11.5 and openmpi 3.0.1 working with pmix. > >> > >> everything compiled, but when i run something it get > >> > >> : symbol lookup error: /openmpi/mca_pmix_pmix2x.so: undefined symbol: > >> opal_libevent2022_evthread_use_pthreads > >> > >> i more then sure i did something wrong, but i'm not sure what, here 's what i did > >> > >> compile libevent 2.1.8 > >> > >> ./configure --prefix=/libevent-2.1.8 > >> > >> compile pmix 2.1.0 > >> > >> ./configure --prefix=/pmix-2.1.0 --with-psm2 > >> --with-munge=/munge-0.5.13 --with-libevent=/libevent-2.1.8 > >> > >> compile openmpi > >> > >> ./configure --prefix=/openmpi-3.0.1 --with-slurm=/slurm-17.11.5 > >> --with-hwloc=external --with-mxm=/opt/mellanox/mxm > >> --with-cuda=/usr/local/cuda --with-pmix=/pmix-2.1.0 > >> --with-libevent=/libevent-2.1.8 > >> > >> when i look at the symbols in the mca_pmix_pmix2x.so library the > >> function is indeed undefined (U) in the output, but checking ldd > >> against the library doesn't show any missing > >> > >> any thoughts? > >> _______________________________________________ > >> users mailing list > >> users@lists.open-mpi.org > >> https://urldefense.proofpoint.com/v2/url?u=https-3A__lists.open-2Dmpi.org_mailman_listinfo_users&d=DwIGaQ&c=pZJPUDQ3SB9JplYbifm4nt2lEVG5pWx2KikqINpWlZM&r=HOtXciFqK5GlgIgLAxthUQ&m=XE6hInyZVJ5VMrO5vdTEKEw3pZBBVnLE7U8Nm67zj2M&s=_sgJVrkRzlv7dIYMvtMfj26AJdbH-fcOOarmN7PyJCI&e= > > > > _______________________________________________ > > users mailing list > > users@lists.open-mpi.org > > https://urldefense.proofpoint.com/v2/url?u=https-3A__lists.open-2Dmpi.org_mailman_listinfo_users&d=DwIGaQ&c=pZJPUDQ3SB9JplYbifm4nt2lEVG5pWx2KikqINpWlZM&r=HOtXciFqK5GlgIgLAxthUQ&m=XE6hInyZVJ5VMrO5vdTEKEw3pZBBVnLE7U8Nm67zj2M&s=_sgJVrkRzlv7dIYMvtMfj26AJdbH-fcOOarmN7PyJCI&e= > > _______________________________________________ > users mailing list > users@lists.open-mpi.org > https://lists.open-mpi.org/mailman/listinfo/users _______________________________________________ users mailing list users@lists.open-mpi.org https://lists.open-mpi.org/mailman/listinfo/users
