Just 3 small comments: -If you are going to use just GCC, you can get rid of the leading “GCC:”. -You are specifying -O3, which might conflict with other options (lowopt, noopt or even the default (which is -O2)). Probably you should take that out and tune --default-opt-level instead -You are abusing EASYBUILD_OPTARCH. It should work just fine as far as I can see, but the design of that option focused on architectural flags (which ISA to use). You might (or might not) get undesired side effects or conflicting options.

Wrt the compiler options I'm less worried as I consider them well tested. After all the whole Fedora&derivatives world runs on that ;) Alan O'Cais <[email protected]<mailto:[email protected]>> schrieb am Mi. 26.

I can see how that might be a problem for existing software wrt. linking I've run a few naive tests and everything seems but any hints would be welcome Thanks, Martin -- -- http://www.xing.com/profile/Martin_Marcher http://www.linkedin.com/in/martinmarcher Mobil: +43 / 660 / 62 45 103<tel:+43%20660%206245103> UID: ATU68801424 . .
