[SOLVED] update to gcc-4.7.3 killed libgcc_s.so.1

The emerge finished just fine, but my system froze before I could run gcc-config and I had to do a hard reboot. Now when the system boots init fails b/c /sbin/agetty cannot find libgcc_s.so.1. I booted into a livecd and added symlinks from /usr/lib64/gcc/x86_64-pc-linux-gnu/4.7.3/libgcc_s.so.1 to /lib and /usr/lib. I tried chrooting into my gentoo installation, but /bin/bash throws the same error. I also rebooted, but init still has the same error as well. Any thoughts as to what to try next?

Sounds like ldconfig might not have run properly so libraries can't be found.

I've updated to 4.7.3 and am having no problems.

You shouldn't need to make links in /lib or /usr/lib

I'm sorry for being obtuse, but I am confused by the mechanics of going about this. Namely, how do I run /bin/bb or ldconfig if I booting fails and I can't chroot in from a livecd?

As a last gasp way that may or may not work. Do a chroot build with build-packages enabled. Do a "emerge system" which should be only 42 packages including gcc and glibc. Boot up SystemRescue copy the packages over to your "/" and untar them. Then try to change root into your old install. If it works great other wise you're already part way through total clean install. :twisted:

I too upgraded to gcc-4.7.3, the day it was releashed with no obvious problems. From that day onward though I could compile them, but at the install faze, libreoffice ,boost and several others would hang. ( emerge? python? ) Chrome did not build {didnt reallly check where it died compiling or at install} pdfs wouldnt work or install and my existing libreoffice wouldnt run. Tried several rebuilds, python-updater, perl-cleaner , revdep-rebuilds. Gave up and did clean install but this time "amd64" without the tilde "~" :wink:

I would run fsck before mounting from liveCD. You may have filesystem corruption, for various reasons.

I am also having the same problem as Wazoo since the gcc upgrade.

For those that have a problem

Check if you have /etc/ld.so.conf.d/05gcc-x86_64-pc-linux-gnu.conf

Thanks for all of the help, using busybox to chroot into the install worked perfectly. Then I could make symlinks and run gcc-config and ldconfig, which put everything back in working order.

Hello,

It is not a good idea to set a symlink to libgcc, but better remove it and run ldconfig, which will find libgcc at the right place ( /usr/gcc-xXX/lib/ )

Thanks for the suggestion, I should have been clearer about the procedure used. The symlinks were removed after I ran gcc-config, per the last post in this thread.

So as of Sun. May 19, is all this sorted out and an upgrade to gcc-4.7.3 will proceed normally without any manual user intervention required?

When I briefly tried gcc-4.80. I ran into a problem like heilvc described above, but only on Firefox and Chromium, where it failed (hung) in the install phase.

IIRC, it seemly was a python related problem, but I never could solve it, so I went back to gcc-4.7.2-r1.

UPDATE: I just did an emerge -uDN @world, and in the process got the 4.7.3 update (it auto-replaced my 4.7.2-r1), and the file checks suggested by Anon-E-moose above checked out OK, so I guess all is well.
