[gentoo-amd64] /lib32/* missing after system upgrade

[gentoo-amd64] /lib32/* missing after system upgrade

["Einar S. Idsø"]

Hi,

After performing a long-overdue upgrade of my Opteron system today,
almost the entire contents of the /lib32 folder is gone. This is very
nasty since I rely heavily on at least the file
/lib/ld-linux,so.2->/lib32/ld-linux.so.2->/lib32/ld-2.4.so. According to
equery, this file belongs to glibc, which was updated from 2.4-r3 to
2.4-r4. gcc was also upgraded from 3.4.5 to 4.1.1.

On a similar Opteron-system which is still running gcc 4.1.1 and glibc
2.4-r3, the contents of the /lib32 dir are intact. I therefore suspect
the problem to be related to the glibc upgrade, even though it's just a
very minor revision. Unfortunately I am not allowed to downgrade glibc
to the previous version.

Can anyone help me get my /lib32 directory back?

Cheers,
Einar S. Idsø

Some further info: I just remembered that I also changed the symlink for
/etc/make.profile. For some reason I changed it to point to
/usr/portage/profiles/default-linux/x86/2006.0, which doesn't seem
right... I suppose I should rather have used
/usr/portage/profiles/default-linux/amd64/2006.1/(desktop|server)?

Did I just stupidly break my system?

Cheers,
Einar

You have switched to non-multilib profile... Switch it back asap and reemerge 
whatever you emerged on invalid profile.

Is that possible?

from http://www.gentoo.org/doc/en/gentoo-amd64-faq.xml#multilib :
"Currently you cannot switch from a no-multilib to a multilib-enabled
profile, so think over your decision twice before you use the
no-multilib profile."

The reason it's not possible is because it breaks the system.
portage does not prevent you from changing to an incompatible profile.

Understood, I was thinking of "Switch it back asap and reemerge" as
impossible.  I have a deep respect for portage, but I absolutely do
not expect it to protect me from myself ;)

In theory, the only big damage is likely to be the toolchain,
glibc/gcc/binutils/sandbox.  Of course, with those damaged, getting stuff
working again is going to be "interesting" to say the least.  However, one
should be able to recover by resetting the profile correctly, then using
quickpkg on the toolchain packages out of an amd64 stage-X install, and
merging those binary packages directly over the fubar-ed system.  That
should recover a working toolchain, after which one would of course emerge
--emptytree --deep --update world, to finish the recovery.

If you've been running FEATURES=buildpkg for some time before the screwup,
and caught the problem early enough (or you can use another amd64 machine
as here), you can remerge anything that wasn't merged on the bad profile
(thus overwriting the last good binpkgs) from the binpkgs.

Yep. Depending on what packages you merged with it you're more or less 
screwed up. Given that gcc and glibc are amongst them, I'd do a reinstall.

*sigh*, stupid me :(

Oh well, it won't be that much of a hassle since I should be able to
just do a tarpipe over ssh from another similar machine on the same
network. That has worked wonders before, and will most likely do so again. x

Thanks for all your replies, most appreciated! :)

- Tar-piped install finished
- System fully upgraded with the proper 2006.1 profile
- All in working order :D
- Lesson learned!
