I'd be interested in that too.
sorry to hijack a thread, but I have to build OpenMPI on Cray XE6 to get an openmpi-only app running and thought it makes sense to have all cray things in one thread.
I'm working with 1.7rc6 tarball and passing these arguments to configure script: --prefix, --with-ugni, --with-ugni-libdir, --with-ugni-includedir
Build is successful and I get mca_btl_ugni.so in lib/openmpi/. However running ompi_info gives this on stderr:
mca: base: component_find: unable to open $prefix/lib/openmpi/mca_btl_ugni: $prefix/lib/openmpi/mca_btl_ugni.so: undefined symbol: ompi_common_ugni_module (ignored)
(I put $prefix in there to shorten the whole text)
and ugni is not loaded and not available as btl.
Since the undefined symbol comes from openmpi, I think this is openmpi thing.
I just tried 1.7rc7r27980 and see this problem still exists.
