Interesting.
For what it's worth, and as you've probably guessed, I do have
another version installation of openmpi.
In fact two, one with the system gcc/gfortran4.2, and one with a
locally compiled gcc/gfortran4.4 .
These both work correctly. The second installation seems to be
interfering with my current attempt,
even though I exported all environment variables I can think of to
point to sun compilers & libraries first,
before configure & compile.
I have oodles of installations of OMPI on my machines; they don't
interfere with each other.
So let's see if we can figure out why yours don't seem to play well
together:
- Check that /opt/mpi_sun and /opt/mpi_gfortran* are actually distinct
subdirectories; there's no hidden sym/hard links in there somewhere
(where directories and/or individual files might accidentally be
pointing to the other tree)
- does "env | grep mpi_" show anything interesting / revealing? What
is your LD_LIBRARY_PATH set to?
- what does ldd on the various .so files in /opt/mpi_sun/lib/ show?
Are they linked against files in their own tree, or the other tree?
- run "mpif90 --showme" through strace; does it show anything
illuminating?
