Hello David,
The development trunk (towards 1.3) is not binary compatible with
the 1.2 branch of Open MPI. Actually, AFAIK, no two versions of
Open MPI are guaranteed to be binary compatible.
You would need to compile and make your component from within
a 1.2 source tree. To be safe, you should use an svn check out that
matches the version you want to use, so in your case:
svn co https://svn.open-mpi.org/svn/ompi/tags/v1.2-series/v1.2.3
and then go from there. There is a chance things will work from the
current 1.2 svn HEAD, but we do not test our code changes for
binary compatibility between versions.
