Undefined symbol: ompi_mpi_abort in openmpi-1.3.2. Confirmed with upstream, this is fixed in upstream 1.3.3. To get the actual error you need to use sth that will actually use this symbol - good example is johntheripper compiled with the mpi flag set. Reproducible: Always Steps to Reproduce: 1.modify ebuild to apply the patch provided - standard error is not verbose enough 2.emerge =openmpi-1.3.2 3.USE="mpi" emerge =johntheripper-1.7.3.1 4.run: mpirun -np 2 john -test Actual Results: dlopen failed on file /usr/lib/openmpi/mca_osc_pt2pt.so: /usr/lib/openmpi/mca_osc_pt2pt.so: undefined symbol: ompi_mpi_abort dlopen failed on file /usr/lib/openmpi/mca_osc_pt2pt.so: /usr/lib/openmpi/mca_osc_pt2pt.so: undefined symbol: ompi_mpi_abort dlopen failed on file /usr/lib/openmpi/mca_osc_pt2pt.so: /usr/lib/openmpi/mca_osc_pt2pt.so: undefined symbol: ompi_mpi_abort mca: base: component_find: unable to open /usr/lib/openmpi/mca_osc_pt2pt: file not found (ignored) dlopen failed on file /usr/lib/openmpi/mca_osc_rdma.so: /usr/lib/openmpi/mca_osc_rdma.so: undefined symbol: ompi_mpi_abort dlopen failed on file /usr/lib/openmpi/mca_osc_rdma.so: /usr/lib/openmpi/mca_osc_rdma.so: undefined symbol: ompi_mpi_abort dlopen failed on file /usr/lib/openmpi/mca_osc_rdma.so: /usr/lib/openmpi/mca_osc_rdma.so: undefined symbol: ompi_mpi_abort mca: base: component_find: unable to open /usr/lib/openmpi/mca_osc_rdma: file not found (ignored) John the Ripper password cracker, version 1.7.3.1-all-3 Copyright (c) 1996-2008 by Solar Designer and others Homepage: http://www.openwall.com/john/ Expected Results: lack of above error messages :) Also check symbols in libmpi.so.

Thanks for Jeff Squyres from openmpi for helping with this bug!
