Hi there, I'm building OpenMPI 1.8.3 on a system where I explicitly don't want any of the BTL components (they tend to break my single node jobs).
./configure CC=gcc CXX=g++ F77=gfortran FC=gfortran --prefix=$QC_EXT_LIBS/openmpi --enable-static --enable-mca-no-build=btl Building gives me this error in the vt component - it appears to be expecting some Infiniband stuff: CCLD otfmerge-mpi /u/sciteam/leeping/opt/qchem-4.2/ext-libs/openmpi-1.8.3/ompi/contrib/vt/vt/../../../.libs/libmpi.so: undefined reference to `ibv_free_device_list' /u/sciteam/leeping/opt/qchem-4.2/ext-libs/openmpi-1.8.3/ompi/contrib/vt/vt/../../../.libs/libmpi.so: undefined reference to `ibv_alloc_pd' /u/sciteam/leeping/opt/qchem-4.2/ext-libs/openmpi-1.8.3/ompi/contrib/vt/vt/../../../.libs/libmpi.so: undefined reference to `ibv_close_device' /u/sciteam/leeping/opt/qchem-4.2/ext-libs/openmpi-1.8.3/ompi/contrib/vt/vt/../../../.libs/libmpi.so: undefined reference to `ibv_dealloc_pd' /u/sciteam/leeping/opt/qchem-4.2/ext-libs/openmpi-1.8.3/ompi/contrib/vt/vt/../../../.libs/libmpi.so: undefined reference to `ibv_destroy_qp' /u/sciteam/leeping/opt/qchem-4.2/ext-libs/openmpi-1.8.3/ompi/contrib/vt/vt/../../../.libs/libmpi.so: undefined reference to `ibv_create_cq' /u/sciteam/leeping/opt/qchem-4.2/ext-libs/openmpi-1.8.3/ompi/contrib/vt/vt/../../../.libs/libmpi.so: undefined reference to `ibv_get_sysfs_path' /u/sciteam/leeping/opt/qchem-4.2/ext-libs/openmpi-1.8.3/ompi/contrib/vt/vt/../../../.libs/libmpi.so: undefined reference to `ibv_open_device' /u/sciteam/leeping/opt/qchem-4.2/ext-libs/openmpi-1.8.3/ompi/contrib/vt/vt/../../../.libs/libmpi.so: undefined reference to `ibv_create_qp' /u/sciteam/leeping/opt/qchem-4.2/ext-libs/openmpi-1.8.3/ompi/contrib/vt/vt/../../../.libs/libmpi.so: undefined reference to `ibv_query_device' /u/sciteam/leeping/opt/qchem-4.2/ext-libs/openmpi-1.8.3/ompi/contrib/vt/vt/../../../.libs/libmpi.so: undefined reference to `ibv_get_device_list' /u/sciteam/leeping/opt/qchem-4.2/ext-libs/openmpi-1.8.3/ompi/contrib/vt/vt/../../../.libs/libmpi.so: undefined reference to `ibv_get_device_name' /u/sciteam/leeping/opt/qchem-4.2/ext-libs/openmpi-1.8.3/ompi/contrib/vt/vt/../../../.libs/libmpi.so: undefined reference to `ibv_destroy_cq' collect2: error: ld returned 1 exit status make[10]: *** [otfmerge-mpi] Error 1 I've decided to disable the vt component since I doubt I'm using it, but this could be good to know.
