[gentoo-amd64] Glibc Update Breaks Open/LibreOffice -- Can't Downgrade

[gentoo-amd64] Glibc Update Breaks Open/LibreOffice -- Can't Downgrade

[Frank Peters]

Hello,

Today my system automatically updated glibc from 2.12-rc2 to 2.12-rc3.
Shortly afterwards I tried to start OpenOffice and it would not start.
The error message:

Inconsistency detected by ld.so: dl-deps.c: 622: _dl_map_object_deps: Assertion `nlist > 1' failed!

(The same problem is reported here: http://forums.gentoo.org/viewtopic-p-6744468.html)

Apparently this is due to the glibc update.  A quick fix (since I need
OpenOffice) would be to simply downgrade back to glibc-2.12-r2, but
emerge will not allow me to do it:

 * Sanity check to keep you from breaking your system:
 *  Downgrading glibc is not supported and a sure way to destruction
 * ERROR: sys-libs/glibc-2.13-r2 failed (setup phase):
 *   aborting to save your system

I'm not going to break my system.  How do I override this?

Note:  I am not using the compiled Gentoo version of OpenOffice.
My installation is the binary version from the OO web site.
Also, LibreOffice, which I installed (from binary) as a possible
fix, gives the same error message.

no need for that, a simple revdep-rebuilt solves this.

I saw the same with vlc - revdep and all problems were gone. LO works too.

Seriously guys...how long are you using gentoo?

As I mentioned, I am not using the Gentoo OpenOffice.
Doing revdep-rebuild on my system indicates that everything
is OK.

I suppose that the OpenOffice/LibreOffice folks have to rebuild
*their* binaries.

But is there a way to override the emerge refusal to allow
a downgrade to glibc?  That is what I need to do.

Take a look at this page:

And also this forum topic:

Good luck! :)

Thanks for these links.

What a mess!  In my case there would be no problem because
absolutely nothing was built against the new glibc.

However, I found another solution.  I did not realize that
Gentoo offers a binary OpenOffice package.  Installing
this openoffice-bin package now gives me an OpenOffice
that starts with the new glibc update.

So the new question is why does the binary from OO/LO
fail to start while the Gentoo binary shows no problem?
AFAIK they are the same package, but the directory structures
are different.

Anyway, I'm glad to have OO running.

And the difference between versions may have been trivial, anyway.

Was one x86 and the other amd64?

one is compiled by the ooo guys for some setup they consider 'standard'. The 
other compiled against gentoo stable tree.

Huge differences. Really.

Well, I checked the ebuild for openoffice-bin and it looks like
the plain OO rpm files from the OO web site are downloaded, unpacked,
and installed.

Anyway, there are other reports of problems with glibc-2.13-r3 and
breakages with OO and LO and other things.

On my system, nothing else seems to be affected.

copy content of previous glibc ebuild to to name of latest ebuild of 
glibc, and emerge same version of glibc "as portage" see it so, but it 
will actuly downgrade screew up your box, warning

pretend i not have used gentoo / funtoo in the last 10 years :)

btw you could fix more by NOT use precompiled software

If you edit the glibc-2.13-r3 entry in /var/db/pkg to call it -r2,
you should be able to sneak in a downgrade.

Something like (untested):

:; mv /var/db/pkg/sys-libs/glibc-2.13-r3 /var/db/pkg/sys-libs/glibc-2.13-r2
:; cd /var/db/pkg/sys-libs/glibc-2.13-r2
:; mv glibc-2.13-r3.ebuild glibc-2.13-r2.ebuild
:; perl -pi -e 's/2.13-r3/2.13-r2/g' PF
:; bunzip2 environment.bz2
:; perl -pi -e 's/2.13-r3/2.13-r2/g' environment
:; bzip2 environment

would probably convince portage that you have -r2 installed.  It should
then let you re-install -r2 via emerge =sys-libs/glibc-2.13-r2.

I found a backup of my old stage3, chroot(2)ed to that, upgraded it to
2.13-r2, used quickpkg to make a pkg file (forgot to specify --buildpkg)
and untar(1)ed that over / to get a working box again.

Copy or overlay the one glibc ebuild with a copy of the good one. It
is hard to tell which ebuilds you mean, but I think the difference may
be just the patch set.
