If I follow correctly, the problem is not with the Self CRS component
USING lt_dl*(), but rather a failure is occurring when one is trying to
dynamically load the component itself. If that is correct, then I'd
guess that some automake/libtool magic incantation is missing. It may
be as simple as needing $(LIBLTDL) somewhere in the Makefile.am.

Once upon a time, the Self CRS module worked correctly, but I admit
that I have not tested it in a long time.
The Self CRS component uses dl_open and friends to inspect the running
process for a particular set of functions. When I try to run an MPI
program that contains these signatures I get the following error when
it tries to resolve lt_dlopen() in opal_crs_self_component_query():
------------------
my-app: symbol lookup error:
/path/to/install/lib/openmpi/mca_crs_self.so: undefined symbol: lt_dlopen
------------------
I am configuring with the following:
------------------
./configure --prefix=/path/to/install \
--enable-binaries \
--with-devel-headers \
--enable-debug \
--enable-mpi-threads \
--with-ft=cr \
--without-memory-manager \
--enable-ft-thread \
CC=gcc CXX=g++ \
F77=gfortran FC=gfortran
------------------
The source code is at the link below:
https://svn.open-mpi.org/trac/ompi/browser/trunk/opal/mca/crs/self
Does anyone have any thoughts on what might be going wrong here?
Thanks,
Josh
