Passant, you have to manually download and apply https://github.com/pmix/pmix/commit/2e2f4445b45eac5a3fcbd409c81efe318876e659.patch to PMIx 2.2.1 that should likely fix your problem.
As a side note, it is a bad practice to configure --with-FOO=/usr since it might have some unexpected side effects. Instead, you can replace configure --with-slurm --with-pmix=/usr --with-pmi=/usr --with-libevent=/usr with configure --with-slurm --with-pmix=external --with-pmi --with-libevent=external to be on the safe side I also invite you to pass --with-hwloc=external to the configure command line Cheers, Gilles On Sun, Feb 24, 2019 at 1:54 AM Passant A.
