Hello,

I am currently a student at Ecole Central Paris in Paris following the cours of High Performance Computing which  demand the installation of mpich2. Possessing a macbook air with OSX Lion version 10.7.5, I have met a problem when install mpich2 at the step "make". I don't know what to do now.
I have enclosed the c.txt, m.txt, mi.txt files for you. Thank you for help.

Any reason you can't use MacPorts to install mpich?

Or homebrew, if you don't prefer MacPorts.  Eric maintains a nice package in MacPorts specifically to make this process easy, and I do the same for homebrew:

"sudo port install mpich"

OR

"brew install mpich"
