I have tried 1.8.8, 10.0.2rc3 and master with the following configure options (and --prefix)
--enable-debug --with-verbs --enable-openib-connectx-xrc --with-mxm=/opt/mellanox/mxm --with-fca=/opt/mellanox/fca --with-hcoll=/opt/mellanox/hcoll In all three cases the configure output contains one of the following: --- MCA component coll:hcoll (m4 configuration macro) checking for MCA component coll:hcoll compile mode... dso checking --with-hcoll value... sanity check ok (/opt/mellanox/hcoll) checking hcoll_api.h usability... yes checking hcoll_api.h presence... yes checking for hcoll_api.h... yes checking for library containing hcoll_get_version... no configure: error: HCOLL support requested but not found. Aborting OR --- MCA component coll:hcoll (m4 configuration macro) checking for MCA component coll:hcoll compile mode... dso checking hcoll/api/hcoll_api.h usability... yes checking hcoll/api/hcoll_api.h presence... yes checking for hcoll/api/hcoll_api.h... yes looking for library in lib checking for library containing hcoll_get_version... no looking for library in lib64 checking for library containing hcoll_get_version... no configure: error: HCOLL support requested but not found. Aborting Where the first output is seen with v1.8 and the second with v1.10 and master. The contents of config.log (shown for master, below) indicates that the test for hcoll_get_version has failed *not* due to lack of that symbol, but rather due to some unsatisfied shared library dependency: configure:241636: gcc -std=gnu99 -o conftest -g -finline-functions -fno-strict-aliasing -pthread -I/hpc/home/USERS/phhargrove/SCRATCH/OMPI/openmpi-master-linux-x86_64-mxm/openmpi-dev-3300-gb7b4231/opal/mca/hwloc/hwloc1111/hwloc/include -I/hpc/home/USERS/phhargrove/SCRATCH/OMPI/openmpi-master-linux-x86_64-mxm/BLD/opal/mca/hwloc/hwloc1111/hwloc/include -I/hpc/home/USERS/phhargrove/SCRATCH/OMPI/openmpi-master-linux-x86_64-mxm/openmpi-dev-3300-gb7b4231/opal/mca/event/libevent2022/libevent -I/hpc/home/USERS/phhargrove/SCRATCH/OMPI/openmpi-master-linux-x86_64-mxm/openmpi-dev-3300-gb7b4231/opal/mca/event/libevent2022/libevent/include -I/hpc/home/USERS/phhargrove/SCRATCH/OMPI/openmpi-master-linux-x86_64-mxm/BLD/opal/mca/event/libevent2022/libevent/include -I/opt/mellanox/hcoll/include -L/opt/mellanox/hcoll/lib conftest.c -lhcoll -lrt -lm -lutil -lrt -lm -lutil >&5 /usr/bin/ld: warning: libibnetdisc.so.5, needed by /opt/mellanox/hcoll/lib/libhcoll.so, not found (try using -rpath or -rpath-link) /opt/mellanox/hcoll/lib/libhcoll.so: undefined reference to `ibnd_iter_nodes_type@IBNETDISC_1.0' /opt/mellanox/hcoll/lib/libhcoll.so: undefined reference to `ibnd_destroy_fabric@IBNETDISC_1.0' /opt/mellanox/hcoll/lib/libhcoll.so: undefined reference to `ibnd_load_fabric@IBNETDISC_1.0' /opt/mellanox/hcoll/lib/libhcoll.so: undefined reference to `ibnd_iter_nodes@IBNETDISC_1.0' collect2: ld returned 1 exit status This is on the "mir13" head node of the Mellanox DMZ cluster. So, Mellanox should be able to either tell me what I have done wrong, or else reproduce for themselves. -Paul -- Paul H.
