Subject: Re: [OMPI docs] How to compile OpenMPI applications?

Basically, yes. But what are the "right librarlies" and the necessary
header files? I would like to find documentation which does *not* assume
a "black box" (mpicc) which does all the "magic".

Of course, I could just look at the example output of mpicc --showme,
but then I couldn't be sure that this is generally the right LD and CC
flags - therefore I'm looking for a documentation which covers the
compilation requirements generally.
