Hi Jeff,
Thanks, I will give that a try and repost to the list if problems
remain. I am kind of surprised that compiling with -fpic is not done by
default on a Linux system, since OpenMPI builds as a set of shared

Bummer -- I thought I had replied to that one (perhaps I'm thinking
that multiple people have posted this and I've replied to some but
not all of them).
Brock is correct that using "-fpic" to compile your MPI C++ app
should solve the problem. This information *used* to be posted on

Try compiling with
-fPIC, that solved our (Andrew Caird is my boss) problem, not
optimal but it worked, but i have not tried it with pgi-7.0 only
pgi-6.0/6.1
Let me know if that works

Thanks Adrian - that's a useful suggestion, I'll explore that.

Hello,
This is a follow up to a message originally posted by Andrew J Caird on
2006-08-16. No one ever replied to Andrew's message, and I am experiencing
exactly the same problem with a more recent version of OpenMPI (1.2.1) and
the PGI compiler (7.0). Essentially, the problem is that if you lin
