I updated mpich 3.1 to 3.1.4 in rawhide. I wouldn't have thought this would make a difference, but apparently upstream decided to rename libraries (libmpich.so.12 -> libmpi.so.12) and drop a sub-library (libopa.so.1), apparently not having any understanding of how sonames work. Or perhaps I'm just naive in thinking a 3.1 -> 3.1.4 version jump shouldn't introduce ABI incompatible changes. So, things need to be rebuilt in rawhide. I checked in the changes to F22 have haven't built yet. mpich needs a rebuild in F22 though I think for fortran mod api changes. -- Orion Poplawski Technical Manager 303-415-9701 x222 NWRA, Boulder/CoRA Office FAX: 303-415-9702 3380 Mitchell Lane orion@xxxxxxxx Boulder, CO 80301 http://www.nwra.com -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
