[gentoo-catalyst] chroot: failed to run command `/tmp/stage1-preclean-chroot.sh': No such file or directory

[Matt Turner]

At the end of my stage1 build, I get (sorry for gmail's linewraps)

"""

But the /tmp/stage1-preclean-chroot.sh _is_ there, with proper permissions, etc.

bcm91250a-be space # ls -lh
catalyst/tmp/default/stage1-mips4_n32-20101114/tmp/stage1root/tmp/stage1-preclean-chroot.sh
-rwxr-xr-x 1 root root 435 Nov  4 09:23
catalyst/tmp/default/stage1-mips4_n32-20101114/tmp/stage1root/tmp/stage1-preclean-chroot.sh

So I tried chrooting into the stage1root:

bcm91250a-be space # chroot
catalyst/tmp/default/stage1-mips4_n32-20101114/tmp/stage1root/
/bin/bash
chroot: failed to run command `/bin/bash': No such file or directory

But bash _is_ there, and does work. (=sys-apps/bash-4.1_p9)

So there must be some strange problem with glibc and bash. How can I
figure out what's causing this?

Can you check with strace which file it is that is actually missing?

Yes, good idea.

/space/catalyst/tmp/default/stage1-mips4_n32-20101114/tmp/stage1root/
/bin/bash
chroot: failed to run command `/bin/bash': No such file or directory

It actually reports
execve("/bin/bash", ["/bin/bash"], [/* 27 vars */]) = -1 ENOENT (No
such file or directory)

But what the heck?

bcm91250a-be space # ldd
/space/catalyst/tmp/default/stage1-mips4_n32-20101114/tmp/stage1root/bin/bash
        libncurses.so.5 => /lib/libncurses.so.5 (0x2b5da000)
        libdl.so.2 => /lib/libdl.so.2 (0x2b630000)
        libc.so.6 => /lib/libc.so.6 (0x2b644000)
        /lib32/ld.so.1 (0x2b5aa000)

All these files exist and appear valid except /lib32/ld.so.1. /lib32
is supposed to be a symlink to /lib, but for whatever reason it wasn't
in my seed stage. I think this is definitely the problem. I'll report
back with confirmation.

Thanks Peter!

Indeed. This was the problem.
