The glibc 2.6 thread

Vlad.Sharp · Posted: Mon Jun 04, 2007 6:10 pm Post subject: The glibc 2.6 thread

Ok, so after having installed Fedora Core 7 from the network the other day, I noticed that it was using glibc 2.6. The "stable" final version was released on 1st June, and glibc 2.6 is still masked in portage - so I decided to create this thread about issues that need workarounds while using glibc 2.6 in gentoo (I've heard there are a couple of workarounds needed, not sure of the links to sources.)

I will be installing gentoo again using Gcc 4.2 and Glibc 2.6, so please join me in my quest for a better gentoo on glibc 2.6 via this support thread! :roll:

Please post issues you encounter with glibc 2.6 - bugs and workarounds (and patches would be nice

)

(P.S. I'm not trying to say that gentoo sucks because it doesn't have the latest and greatest glibc - that's a matter of extensive testing... So let's test it so that it can be unmasked!)

I too am giving gcc 4.2 and glibc 2.6 a shot. However I took a look at the ebuild and it said something to the effect of not to keyword and to wait for 2.6.1. Anyone know the reason for that?

First thing that i've found is that emacs segfaults...I'll see if recompiling it helps...

While doing emerge -e system, the *expected* gzip, cpio (etc.) failures occur. Errors about the glibc futimens.

There are patches available, and they're in the Palgene overlay: http://palgene-overlay.googlecode.com/svn/experimental/

And where can I find what's new in glibc 2.6 ?
I can't find any changelog for it.

I found a changelog on their cvs repository - doesn't seem to be much though: http://sources.redhat.com/cgi-bin/cvsweb.cgi/~checkout~/libc/NEWS?rev=1.176&content-type=text/plain&cvsroot=glibc&only_with_tag=glibc-2_6

Vlad.Sharp and Rion, I'd like to thank you both.

I don't see any reason why I should upgrade to 2.6...
And I'm curious why it is a major release, and not something like 2.5.3, but that's another story.

PL locale is kinda broken in glibc 2.6, same symptoms as here: https://forums.gentoo.org/viewtopic-p-3971453.html#3971453

(patch fails)

try ebuild /usr/portage/sys-libs/glibc/glibc-2.6.ebuild digest and see what happens.

Seems like a couple of things have changed in the source after all

I don't know about filing a bug, but perhaps asking Kevin Quinn about the issue might be the *best* thing to do? http://overlays.gentoo.org/dev/kevquinn (And yes, the glibc 2.6 failure is what put me off hardened this time round)

app-arch/cpio-2.7-r1 fails with this:

Seems like anything that has to do with archiving is failing to build...cpio, tar, gzip...I'll have to get those patched versions. BTW mozilla-firefox (2.0.0.4) is crashing like crazy on me now. Anyone else experiencing this?

Well glad I'm not the only one. I've been trying to do an emerge -e world for a day now, keeps halting on errors...i should really use a script or something. I'm using x86, unfortunately I don't have the option to test out an amd64 platform as I have a core duo, not a core 2 duo. I hope its just conflicting library's at the moment. I'll also try deleting .mozilla and see if that does anything. Someone asked about my cflags, their not aggressive at all, I think its the standard that gentoo ships with. Here's my emerge --info:

@Vlad.Sharp: no idea man. It could be that i haven't recompiled everything yet. As of right now I have about 140 more packages to go.

I may get laughed at for this but I've noticed myspace slowing down alot because of the flash ads and flash music playing on people's pages. It works fine (by works I mean the scroll isn't hella laggy) when I'm at someone's pictures page. Any suggestions? Or should i see if this irons out after i re-emerge everything.
