Folks, I recently installed libnl3-devel rpm on my centos 7 box, reconfigured and recompiled ompi, and ompi_info now crashes.
it seems the root cause is an obscure conflict between libnl and libnl3. libnl is indirectly required by the common_verbs mac (OFED libraries do need it) and libnl3 is required by reachable_netlink mca when available. currently, there are two workarounds available 1. uninstall libln3-devel rpm, so reachable_netlink mca uses libnl 2. configure with --without-verbs so no mac requires libnl right now, my best bet would be not to use libnl3 when configure'd with --verbs and OFED is available. any thoughts ? Cheers, Gilles
