Subject: [OMPI users] unresolved symbol mca_base_param_reg_int

Hi,
I am having a problem running application with OpenMpi version 1.4.1.
The system works with version 1.2.7, but fails with version 1.3.4 and
1.4.1. (These are the only version I have tried).
My application is linked against a shared library which does a dlopen of
a 2nd shared "C" library which is compiled and linked using mpicc. The
application and first shared library are C++.
I rebuild and relink the 2nd shared library each time I change the
openmpi build.
When MPI_init is called I get the following error
symbol lookup error: /opt/openmpi/lib/openmpi/mca_paffinity_linux.so:
undefined symbol: mca_base_param_reg_int
This does NOT occur with OpenMpi version 1.2.7, Or if I build OpenMpi as
a static library, and then link against this static library.
I am building a default openmpi except for --prefix=/opt/openmpi and
--enable-static --disable-shared for static library build.
I would link to be able to use non static openmpi build.
Any suggestion on what I am doing wrong?
Thanks Nev
