Subject: Re: [OMPI users] Problem with linking on OS X

Hi Tomek,

I'm using 10.5.7, and just went through a painful process that we
thought was library related (but it wasn't), so I'll give my less-than-
learned response, and if you sill have difficulties hopefully others
will chime in:

What is the result of "which mpicc" (or whatever you are using for
your compiling/linking? I'm pretty sure that's where the library
paths get set, and if you are calling /usr/bin/mpicc you will get the
wrong library paths in the executable.

You do not need to set DYLD_LIBRARY_PATH. I don't have it set and my
mpi applications run fine.

Did 4 work?

Cheers, Jody
