[mpich2-dev] [ewg] Problems with mvapich2-1.5.1 - shared library is missing hwloc_* functions.

[Jonathan Perkins]

Hello Mike,
Below I'm pasting a note that I've sent to Vlad and the EWG mailing list.
It looks like the list is not yet functional.  Our nearly uploaded source
rpm resolves this issue and will be included into OFED's nightly build.  If
you'd like to try this before then, you can grab it from
~perkinjo/ofed_1_5/mvapich2-1.5.1-0.1.20100910svn4174.src.rpm and replace
the existing rpm in the OFED build system.

Also, please send future questions regarding mvapich2 to
mvapich-discuss at cse.ohio-state.edu.

I've found the problem that caused the missing symbols.  I've uploaded a new
source rpm that contains the fix.  It is pointed to by the latest.txt file
and is available at
~perkinjo/ofed_1_5/mvapich2-1.5.1-0.1.20100910svn4174.src.rpm.
