Well, a couple of things come to mind - see below On Mar 20, 2013, at 9:41 AM, Bruno Cramer <bruno.cra...@gmail.com> wrote:

Look at the executable - apparently, you tried to run the ".c" source code instead of the compiled executable :-) > ----------------------- > typing echo $LD_LIBRARY_PATH I should get something like > /usr/lib/mpi/gcc/openmpi/lib.

I suspect that your original LD_LIBRARY_PATH was empty, so now the path starts with a ":" and makes bash unhappy. Try reversing the order as above and it might work. > > > > 1) Openmpi installation in PC2 > In OpenSuse v 12.1 64b I installed openmpi-1.4.3 downloading it from the > openmpi site. > No error occured during ./configure, make, make install process. > The environment settings change a little but are very similar to those > mentioned under PC1. > The same message as above is occuring. > > in this case typing echo $LD_LIBRARY_PATH I get the correct output from the > mpi library as /usr/local/lib64 and the executables are in /usr/local/bin. > > > Any help is wellcome > > > Regards > Bruno > _______________________________________________ > users mailing list > us...@open-mpi.org > http://www.open-mpi.org/mailman/listinfo.cgi/users
