The glibc 2.6 thread

Master Shake · Posted: Fri Jul 13, 2007 3:28 pm Post subject:

If your trying to patch a glibc 2.5 patch against glibc 2.6 it might fail. The patch might need to be rewritten. There are a number of problems that this could be. Find a dev and ask them on irc. I'll look into the patch, but i'm not sure if I'll find anything.

Hmm, glibc-2.6 just hit ~arch. I hope no problems waiting.

I'll be compiling it in a minute. Report later.

does anybody know what is the lure of glibc-2.6? Anything worth upgrading for (from 2.5)?

Compiled ok, but now gpm fails to compile:

I would like the anoying problems fixed first before this goes stable. Mozilla in particular. When's the next version of this coming out?

octoploid thanks, i'm running 22-rcX on this machine.

So i guess i'll have to upgrade to final 22 or some derivate :wink:

After doing "emerge -uDN world" (glibc being upgraded to 2.6) every program I have tried shows this when running it with valgrind:

kernelOfTruth · Posted: Sun Jul 15, 2007 10:36 pm Post subject:

it now also compiles under hardened (~x86), everything seems to be a little faster - great experience :wink:

lets see where the issues are :roll:

No, I think it just means that there are no linuxthreads anymore in glibc! (part of the path for the build is something like build-default-linux-nptl). Which is good

(But what about 2.4x kernels? I wonder if there are linuxthreads for them still with the new glibc...)

maybe 2.4 is in fact going to be obsoleted.

i read somewhere that 386 is going to be dropped from glibc in the future
due to lack of certain cpu features, and glibc is going to support >=486 cpus in x86 family.

After update to glib 2.6 I had segmantation faults everywhere.
After restart, the system is now unusable!! During boot, I get:

INIT:PANIC: segmentation fault

I cant chroot from liveCD because bash seg faults....
What can I do to restore system?

emerge -e system and re-emerge kernel (& drivers) for a start. That should (fingers crossed) get you booting correctly.

Edit: oops - forgot about the Bash segfault. See below

After Upgrading I have used a script to reemerge system and world, Im up to about 1750 packages emerged of a total of 2200, so far the only problems I have encountered were valgrind that needs glibc-2.5 to compile and splashutils which wont compile because of a missing nptl flag but the ebuild is easily adjusted not to look for nptl in glibc and emerges just fine. So really Im just not sure if valgrind will work now

glibc-2.6 doesn't even compile here

scourge · n00b Joined: 13 Jun 2005 Posts: 51 Location: Germany

No problems here, running great on 2 boxes (~x86 and ~amd64, compiled using gcc 4.2.0).
I'm recompiling world now with gcc 4.2. 238 packages to go and not a single one failed so far.

Hmm... I think I should have read this thread before doing an emerge -uvDN world. Looks like I had set glibc to ~x86 (might not be the smartest thing to do

) and now it's updated to 2.6. Well... So far everything has compiled fine.

Is it necessary to recompile the whole world? I'm doing a emerge -e system at the moment (126 of 148 running) and would very much like to have the compiling done in few hours. I got the computer also as a digi-tv-box with vdr and that doesn't work perfectly while the computer is under heavy load. I got portage_niceness set to 19, but it still makes the vdr stop once in a while.

But we'll see how my box works after recompiling... Luckily I got a working Debian on another drive so if this time I manage to break my Gentoo, my computer is still usable.

Still going well... System compiled ok and now emerging world. 300 packages compiled with just a few fails. Of those only one was real. Others were some kernel module which requires something I no longer have in my kernel (don't have the hardware neither) and Googleearth (gotta see if the ebuild was in my own overlay or was it by layman, anyways the filesize didn't match and it failed). The real one was linux-dvb-apps (or something like that). I'll try to compile a different version of that after I got the rest of the world done.
