you should be able to have it work by running crossdev with --with-headers
(In reply to comment #1) > you should be able to have it work by running crossdev with --with-headers > I had the same bug on AMD64 host and I can confirm that running crossdev with --with-headers fixes it for target i586, but not for target powerpc, where compiler at gcc stage1 still complains about missing stdlib.h and so on. For bigger confusion, "crossdev --help" does not provide info about --with-headers switch, and "man crossdev" complains about missing man pages.
Same problem building for a i686-pc-linux-gnu target. --with-headers doesn't fix it, now cross-glibc-headers fails to compile: (...) checking for suffix of object files... configure: error: cannot compute suffix of object files: cannot compile See `config.log' for more details. (...) I've backed up the config.log and can attach it if required, but it doesn't hold much information..
if your glibc headers is failing with "cannot compute suffix of object files", then you're hitting a bug in portage. nothing i can do about that.
*** Bug 228969 has been marked as a duplicate of this bug. ***
It may be that I left the gcc version at "latest" which on my system is 4.2.3. Crazy how it tried to build 4.3.1 for the crossdev toolchanin. When I specified the version of 4.2.3 it built fine. I might wager that if I had native gcc 4.3.1 as my compiler that it might build 4.3.1 as the crossdev tool just fine. If I get some time I will install gcc 4.3.1 and test that theory.
i'm not going to research getting gcc-4.3 built w/out headers crossdev runs with --with-headers by default now
I can confirm that --with-headers builds fine now, so the portage bug should be gone. Just to let you know ;)
