[R-SIG-Mac] GCC on Lion and above

Hi All,

HPC seem to be maintaining the gcc toolchain up to date (they have GCC 4.7 compiled with autovectoring using OpenMP…)


BUT the page  http://r.research.att.com/tools/  says "do not use compilers from HPC, they won't work correctly!” Is that the case?

Also, I wondered if http://www.macports.org might be the way to go to get a version of gcc with a non-crashing OpenMP library?

best wishes and thanks for your help


PS: The att.com page talks about install disks for OS X, but I think it’s all via the app store now, including X Code.
