George I knew that was the answer to Calin's question, but I still would like to understand the issue:
by default, the openMPI installer installs the libraries in /usr/local/lib, which is a standard location for the C compiler to look for libraries. So *why* do I need to explicitly specify this with LD_LIBRARY_PATH? For example, when I am compiling with pthread calls and pass -lpthread to gcc, I need not specify the location of libpthread.so with LD_LIBRARY_PATH. I had the same problem as Calin so I am curious. This is assuming he has not redirected the installation path to some non-standard location. Thanks Durga On 10/19/06, George Bosilca <bosi...@cs.utk.edu> wrote:
Calin, Look like you're missing a proper value for the LD_LIBRARY_PATH. Please read the Open MPI FAW at http://www.open-mpi.org/faq/? category=running. Thanks, george.
