On a number of my Linux machines, /usr/local/lib is not searched by ldconfig, and hence, is not going to be found by gcc. You can fix this by adding /usr/local/lib to /etc/ld.so.conf and running ldconfig ( add the -v flag if you want to see the output ).

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.sowith 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.
