[gentoo-embedded] 64-bit chrooting?

[gentoo-embedded] 64-bit chrooting?

Hi,

I'm trying to build a uclibc system using the Gentoo tarballs on my
amd64 machine. When I try to chroot into it ("linux32 chroot /mnt/gentoo
/bin/bash") I show up as "I have no name@localhost" with a user id of
2^32 or so. There's no change if I don't use linux32 for the chroot.

I can't find anything on the web about this problem. Is this approach
possible with a uclibc chroot? Or do I have to build it from a 32-bit
system?

Thanks,

Peter Ebden

sounds like you disabled 16bit uid syscall support in the kernel

uclibc 0.9.28 does not support the 32bit uid syscalls but ive fixed this in 
latest uClibc svn ...

That fixed it. No idea when/why I disabled those, but hey...

Thanks a bunch for your help :-)
