As I say, I did once. There is no fallback to gcc if icc wouldn't compile a package.
I know, that the ICC compiler promise to give more performance.... However, collect your experience and speak with the gentoo maintainer for the icc compiler packages to have a fallback routine. Would be really great. I am thinking to get in the next month a core I7. To compile gentoo on it, would be SUPER! Am 07.09.2011 10:05, schrieb Stefan G.
