[openib-general] OpenIB 1.0 RC + PathScale problem

[Di Domenico, Michael]

Tim,

The only thing I can suggest is to search your filesystem for another
'libib*' library.  I've noticed that RedHat EL 4 Update 3 comes with
some infiniband libraries under /usr/lib (suse probably does also) and
they conflicted with MVAPICH until I removed the rpm's...
