I just seen it in the tree this morning. I finished compiling 4 boxes and was wondering if I should update.

Is there any improvements that would benefit me? Also, if I do, would it break any packages?

Do you speak Gurumukhi (see changelog)?

Usually glibc just gets larger and slower with every release.

Since you can't downgrade it, and there's not really any new groundbreaking features per the ChangeLog, I would say no.

Well, it seems that glibc-2.9 breaks my Stage1 script... Crap..

I'm going to see if I can compile 2.8 then switch over to 2.9. If it's still broken, then I'm masking it.

Well, compiling glibc-2.8 first, then 2.9 worked perfectly.

Just had to modify my script a little:
Code:
emerge binutils
emerge =sys-libs/glibc-2.8_p20080602
USE="-fortran" emerge =sys-devel/gcc-4.1.2
cd /usr/portage/scripts
./bootstrap.sh                       # This updates glibc-2.8 to 2.9 along with gcc-4.1.2 to 4.3.2
emerge --oneshot --nodeps python     # This updates Python to 2.5
/usr/sbin/python-updater
emerge --unmerge =dev-lang/python-2.4.4-r13  # Gets rid of the old Python
/usr/sbin/python-updater
emerge perl                          # Installs Perl with ALL of the right modules
emerge help2man                      # Required my a package somewhere in emerge system
emerge -e system

I am using ' ACCEPT_KEYWORDS="~x86" ' on all of my boxes. The above compiles perfectly for a Stage1.

yeah, i expected some breakage here and there but it works just fine so far. Running ~arch too.

this may be a bit off topic but I was having a problem which led me to this thread. I've been running some photo slide scanning software (proprietary) and when I updated to the latest version it fails to start with this error:
Code:
 ~/Opt/Vuescan85/VueScan $ ./vuescan
./vuescan: /usr/lib/gcc/i686-pc-linux-gnu/4.1.2/libstdc++.so.6: version `GLIBCXX_3.4.9' not found (required by ./vuescan)
./vuescan: /lib/libc.so.6: version `GLIBC_2.7' not found (required by ./vuescan)

I'm running maybe half or more stable (have several packages keyworded), but I see I'm using glibc-2.6.1. And libstdc++-3.3 if that somehow is affecting the first line up there.

This was just a tarball that I unpacked and is supposedly ready to use without making. I've kept the older version so can use it if I can't resolve the new problem.

I see there is still a glibc-2.7-r2 ebuild as well as some 2.8 ebuilds in portage. Just no idea if I would break something upgrading - same with the libstdc++.

cheers, JD

Word of advice, if you're going ~ARCH on some packages, you might as well do ALL of them that way. I ended up doing that and don't really regret it. Haven't bumped into a problem yet.

You *MIGHT* have to recompile GCC, too. Actually, if you update glibc, you might as well do an "emerge -e world". Sorry. I could be wrong, though.

well, I'm not totally opposed to going ~x86, and in fact am somewhat tempted. I generally like most of my apps to be keyworded, but don't care so much about the underlying system as I want that to be good and stable. I'm running kde-crazy overlay now and the pro-audio overlay so am not adverse to mucking around. If one were to switch to ~ARCH from stable, I wonder if there should be some packages masked out or do you just accept them all? I suppose this is too far off topic and will scan the forums a bit about the subject - but maybe someone has a resource to point me towards.
cheers, jd

If I am reading that output correctly, vuescan was linked with glibc 2.7 and a different version of g++ than the one that your system is selecting by default. You will need to obtain a version compiled with an older glibc, or you will need to upgrade your glibc to at least 2.7. I do not know offhand what version of g++ ships GLIBCXX_3.4.9, but you will need to find and install that version as well.

Upgrading to glibc-2.9 broke xauth for me, meaning ssh X11 forwarding no longer worked. After downgrading from glibc-2.9_p20081201 back to glibc-2.8_p20080602-r1, X11 forwarding returned (see this thread and this bug report).

My experience from glibc-2.9: do NOT install it.
I tried it on 4 machines, had to downgrade them all to 2.8 (patching ebuild, masking and remerging glibc).
On 2 gentoo hardened machines, pthread_create didn't work anymore, which caused a lot of apps to crash/misbehave.
On 2 others several apps crashed in strncasestr functions (one of the changes from 2.8 to 2.9)
I tried deifferent compilers, all the same.
My conclusion: mask it in /etc/portage/package.mask to prevent accidental installs.

Do not touch glibc-2.9 unless you like pain.

glibc 2.9 has been painless so far on my home desktop with KDE 4.2 svn on ~x86.

Should I still downgrade?

What were the 2 apps that crashed in strncasestr, Sash?

@StringCheesian:
It was mc (midnight commander), segfault directly at start if run as root (as normal user it worked), but pressing F3/F4 (the internal viewer/editor), nothing happended
the other one was an internal commandline app.
I didn't investigate much, I just downgraded and this fixed both apps without recompiling.

Hi, same problem with mc here, run in chaos just before xmas.
Downgrading killed my system, so i had to recover from backup.

Perhaps this probs are gone with the "-r1". Anyone tried this??
