So I built openmpi-1.6.5 from the tar ball and of course
everything works fine.... well my simple program got through
Mpi_init and printed its rank.
I configured it very simply :
./configure --prefix=/opt/openmpi-1.6.5
and I noticed that the generated program does not link hwloc like
the program did when I used the system mpicc.
I looked at the installed the openmpi source rpm and took a look
at the configure section and it uses --with-hwloc=/usr so I
reconfigured the openmpi-1.6.5 source with :
./configure \
--prefix=/opt/openmpi-1.6.5 \
--with-hwloc=/usr
and when I rebuilt my program with the generated openmpi my error
returns.
