Nikos,
Your experience with Intel is what I'm after. Aster, the FEA code I'm
going to use is not in Portage hence I will be using it's own build
system. When you've used Intel, have you just exported "CC="icc" or
something similar, as make.conf won't be used? Also, I've read somewhere
that there are libraries that you have to link against that are specific
to the Intel compiler as it does not create libraries that are
comparable with the gcc produced ones - is this true or does the
compiler now "play well" with the gcc world?
Any thoughts,
Andrew
