If you want, I can be a tester for crossdev, as I own a PIII-700 (i686), an iBook (ppc-G3) and an Ultra10 (sparc64). My tests so far: ppc on i686: works sparc64 on i686: see this bug i686 on sparc64: does not compile glibc ppc on sparc64: does not compile glibc i686 on ppc: not tested yet sparc64 on ppc: not tested yet
Ah, I see. You won't have much luck with this, it's a glibc thing. 64-bit support for sparc glibc isn't fully complete yet I believe, or it atleast involves various rituals and sacrifices to dark gods in order to compile it (whether it'd work or not is another thing). Not much I can do about this unfortunately. As for testing crossdev, give it a shot. crossdev-status.sh will show you all the possible target combinations (to date) and what their current status is on each corresponding arch (that was a fun bit of bash to code). i686 targets on other archs will probably not work, and the reason is the headers used to build gcc-bootstrap with. For gcc-bootstrap, I just make a direct copy of /usr/include, hwich isn't really the best thing to do. From my understanding and reading, it seems it's possible (somehow) to "make install-headers" inside of glibc and actually have glibc generate clean headers specifically for the target architecture before the bootstrap compiler is even built. After those headers are in place, the bootstrap compiler builds and so on. I never got very far with that trick though. If anyone can solve it, I'm all ears. You might take a look at Dan Kegel's "crosstool" script, which I used as reference for crossdev for some things to see how he does this step: http://www.kegel.com/crosstool/ Anyways, I'll close this bug off as CANTFIX since the original issue is a glibc thing. If you wanna help with crossdev some more, hang out in #gentoo-embedded. I'll start working on it some more once I fix my x86 box back up and kick out mips stageballs.
Thanks a lot for the explanation :-) When I find some time I will look into the mentioned crosstools and gather information how to set up a cross-compiler. But I target it on a low priority.
