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

[Mike Heinz]

Hello all,

I'm trying to build mvapich2-1.5.1 on an RHEL 5 update 3 system. It builds from the SRPM just fine, but when I try to compile test programs, they don't link. It appears that a set of routines, hwloc_* are missing from the shared library.

I'm building the binary RPM as follows:

[root at homer SRPMS]# rpmbuild --rebuild

Can someone tell me what I'm doing wrong?
