Hi everybody, Taking a look at your website, I could see an issue about compiling Open MPI shared libs using IBM's XLC compiler + libtool:
http://www.open-mpi.org/faq/?category=building#build-ibm-compilers Well, I think we have the solution for this: upgrading libtool to the latest version seems to work well in this case. So, I'd like to ask you to upgrade the libtool used by Open MPI to the latest version (2.2.2 or more), and change this FAQ to provide information about how the user can manually update libtool in older versions of Open MPI. The instructions for upgrading libtool manually are: 1) Get the latest libtool package from http://www.gnu.org/software/libtool 2) Untar, compile and install it 3) Have a fresh and clean Open MPI source tree 4) Inside there, run 'libtoolize --force' 5) Then run 'aclocal' 6) At last, run 'autoreconf --force' After that, you'll be able to build Open MPI without problems :-).
