Sweet -- I put your patch in here: https://github.com/open-mpi/ompi/pull/550 Just to run it by the assembly / IBM/POWER gatekeepers first. :-) > In addition to the one-line patch below, I needed to run autogen.pl with a > new enough config/config.{guess,sub}. > Along the way I noticed > opal/mca/common/libfabric/libfabric/config/config.guess > opal/mca/common/libfabric/libfabric/config/config.sub > opal/mca/hwloc/hwloc191/hwloc/config/config.guess > opal/mca/hwloc/hwloc191/hwloc/config/config.sub > which appear to be too old to recognize powerpc64le and are *not* updated > when autogen.pl is run. It's ok -- we don't run those scripts during OMPI's top-level configure (that's why they're not re-generated during autogen.pl). > I manually updated them, but somebody may want to either commit newer > versions to git or teach autogen.pl to update them. > FWIW, it appears that tarballs *are* generated with up-to-date versions.

But it's overkill / just being defensive; it isn't technically necessary. -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
