But anyway, 2.4 headers newer than our 2.4.22-r1 ebuild are broken (I can't remember exactly how at the moment), and we *really* don't support 2.6 headers at all. In fact, building against them breaks glibc on o32 userland. The only reason we have them in portage at all right now is for our n32 userland (which is broken in other ways because of the headers). Eventually we'll have a sanitized 2.6 headers package that should work, but it may not be anytime soon. Anyway to answer your question, I used crossdev to build a bootstrap C compiler (crossdev -k), then I did the rest by hand. You might also need to get kumba's latest version of the crossdev script from gentoo's viewcvs under gentoo/users/kumba/crossdev/ just to get past the first part. Why do you *need* 2.6 headers anyhow? You can still run a 2.6 kernel with a userland compiled with 2.4 headers. Steve
