Jeff, The requested config.log was attached as openmpi-trunk-solaris11-x64-ib-gcc452-config.log.bz2 in my recent response to the usnic-on-solaris thread: http://www.open-mpi.org/community/lists/devel/2014/01/13637.php
It looks like there were 2 successful probes for ibv_open_device() before the failing one. The failing one says: configure:284324: checking for ibv_open_device in -libverbs configure:284349: gcc -std=gnu99 -o conftest -O3 -DNDEBUG -m64 -finline-functions -fno-strict-aliasing -pthread -I$(top_srcdir) -I$(top_builddir) -I$(top_srcdir)/opal/include -I$(top_srcdir)/orte/include -I$(top_srcdir)/ompi/include -I$(top_srcdir)/oshmem/include -I/shared/OMPI/openmpi-trunk-solaris11-x64-ib-gcc452/openmpi-1.9a1r30146/opal/mca/hwloc/hwloc172/hwloc/include -I/shared/OMPI/openmpi-trunk-solaris11-x64-ib-gcc452/BLD/opal/mca/hwloc/hwloc172/hwloc/include -I/shared/OMPI/openmpi-trunk-solaris11-x64-ib-gcc452/openmpi-1.9a1r30146/opal/mca/event/libevent2021/libevent -I/shared/OMPI/openmpi-trunk-solaris11-x64-ib-gcc452/openmpi-1.9a1r30146/opal/mca/event/libevent2021/libevent/include -I/shared/OMPI/openmpi-trunk-solaris11-x64-ib-gcc452/BLD/opal/mca/event/libevent2021/libevent/include -export-dynamic conftest.c -libverbs -lsocket -lnsl -lm -lsocket -lnsl -lm >&5 ld: fatal: entry point symbol 'xport-dynamic' is undefined collect2: ld returned 1 exit status configure:284349: $? = 1 So, it looks line a bogus "-export-dynamic" argument to gcc is at fault here. -Paul On Thu, Jan 9, 2014 at 2:05 PM, Jeff Squyres (jsquyres) <jsquy...@cisco.com>wrote: > Paul -- > > Can you send the config.log file from this?
