I hope this problem merits being posted here. On OS X (Snow Leopard, and Lion), I cannot seem to build Open MPI.
After a lot of building, I get the error: /bin/sh ../../../libtool --tag=CC --mode=link /opt/pgi/osx86-64/10.9/bin/pgcc -DNDEBUG -O2 -Msignextend -V -export-dynamic -o orte-clean orte-clean.o ../../../orte/libopen-rte.la-lutil libtool: link: /opt/pgi/osx86-64/10.9/bin/pgcc -DNDEBUG -O2 -Msignextend -V -o orte-clean orte-clean.o ../../../orte/.libs/libopen-rte.a /Users/matt/software/openmpi/openmpi-1.4.3/opal/.libs/libopen-pal.a -lutil Undefined symbols for architecture x86_64: "_orte_odls", referenced from: _orte_errmgr_base_error_abort in libopen-rte.a(errmgr_base_fns.o) ld: symbol(s) not found for architecture x86_64 This is with the PGI 10.9 compiler, OpenMPI 1.4.3, platform is 86x64 The README does not list PGI as a compiler that OpenMPI was tested with, and there are notes about it's support for XGrid being broken (I'm not sure if this is related.) I seem to get the error regardless of which configure flags I'm using, just for completeness though, here are the flags I am using: ./configure --prefix=/usr/local/openmpi_pg --enable-mpi-f77 --enable-mpi-f90 --with-memory-manager=none Has anyone else got or fixed this error? I looked at other postings in this list, such as http://www.open-mpi.org/community/lists/devel/2007/05/1590.php , but they didn't help much.
