Are you actually running into a problem? A successful install may still end with "Nothing to be done..." messages.

I have already installed gnu compilers and I tested them. I downloaded the package from the following link: https://www.open-mpi.org/software/ompi/v4.0/ I typed the following command in the command line tool: cd ~/Downloads tar zxvf openmpi-4.0.3.tar.gz cd openmpi-4.0.3 ./configure --prefix=/opt/openmpi make sudo make install Bothe the configure and make processes took a long time to finish. The last line which was related to "install" the product gave me lots of messages like: make[]: Nothing to be done for `install-exec-am. make[]: Nothing to be done for `install-data-am'. Any suggestion or comment will be greatly appreciated, Edris -- Jeff Squyres jsquy...@cisco.com<mailto:jsquy...@cisco.com>
