Those are the three libraries that are typically required. I don't
know anything about xcode, so I don't know if there's any other
secret sauce that you need to use.
Warner -- can you shed any light here?
To verify your Open MPI installation, you might want to try compiling
a trivial MPI application outside of xcode with the simple "mpicc"
wrapper compiler, such as:
mpicc mpi_hello_world.c -o mpi_hello_world
You can also see what underlying command mpicc is invoking with:
mpicc mpi_hello_world.c -o mpi_hello_world --showme
But I will pretty much guarantee that if you have mixed multiple MPI
implementations (LAM and Open MPI) in the same directory tree, things
won't work. It would be best to fully uninstall one (e.g., LAM) and
then re-install the other (e.g., Open MPI). If you've lost the build
directory for LAM, you can download a new source tarball from www.lam-
mpi.org.

Hi all,
I'm working in xcode and i'm trying to build an application that
links against the OMPI libraries. So far i've included the following
files in the build:
libmpi.dylib
libopen-pal.dylib
libopen-rte.dylib
and the errors i get are
Undefined symbols:
.... all the MPI functions you can think of......
as well as a warning: "suggest use of -bind_at_load, as lazy binding
may result in errors or different symbols being used
I've compiled and linked to the static libraries (using ./configure --
enable-static) and i get the same errors. Also, i previously the
latest version of lam/mpi installed. I didn't uninstall it since i
lost the original directory as well as the make and configure
settings. If that is the conflict then any information about how to
resolve it would be good.
Thanks!
Tony
