[mpich-discuss] Error in compiling MPICH on Mac desktop

Fri Oct 30 13:53:57 CDT 2015

<off topic>
With respect to adding your own links, I would suggest that might
confuse Homebrew (don't know for sure, but they use /usr/local/bin)...
MacPorts uses /opt/local, and with it, at least, the intention is that
you don't go around adding your own files (or links) inside of
/opt/local (with the possible exception of config files in etc/ which
you need to modify; frequently as copies of foo.conf.example) .. so
I'm guessing the same is true for Homebrew.
</off topic>

This (-Wa,-q for this case of compilers/OS) is something MPICH can
choose to document for this case if they are interested. Or (sorry if
I'm a broken record here) you can install MacPorts and use 'sudo port
install mpich-gcc5' (most of the dependencies are available as
pre-built packages, so it goes fairly quick.) I'm not sure how the
Homebrew MPICH recipe is configured and how to build this flavor with
it; I suppose you could contact its maintainer.
