Description Stefan de Konink 2004-11-08 01:25:31 UTC

After updating gcc lastnight the CURRENT value in /etc/env.d/gcc/config stays i686-pc-linux-gnu-3.4.2 instead of 3.4.3 as you can imagine the update script is going to behave strange. After the gcc update I (automatically) updated glibc and Firefox + Thunderbird. Both versions won't start anymore because of a non-existing libstdc++.so.6.

Reproducible: Always
Steps to Reproduce:
1. emerge sync
2. emerge portage gcc glibc mozilla-firebird mozilla-thunderbird
3. firefox -> /usr/lib/MozillaFirefox/firefox-bin: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory
4. thunderbird -> /usr/lib/MozillaThunderbird/thunderbird-bin: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory
Actual Results:  
The programs won't start anymore.

Expected Results:  
An working updated version of both packages.

Probably a correct environment in ld.so.conf too, (my guess this must be noticeable for others too),  which is now:
# ld.so.conf autogenerated by env-update; make all changes to
# contents of /etc/env.d directory

Comment 1 Stefan de Konink 2004-11-08 01:31:02 UTC

After manually changing ld.so.conf to the latest version (3.4.3) and do ldconfig I can start both applications again. env-update changes everything back to the old version (3.4.2).

Comment 2 Ian Truelsen 2004-11-08 12:05:45 UTC

I had the same problems and this fix worked for me as well.

Comment 3 Wouter Deconinck 2004-11-09 12:13:37 UTC

Same problem here, but with other programs (kdeinit, pdflatex).  I solved this using 'gcc-config 3.4.3' and 'fix_libtool_files.sh 3.4.3'.

running gcc-config fixed this for me.

Comment 5 filip 2004-11-10 15:13:33 UTC

Same problem here, though I didn't rebuild firefox - only gcc. Also, groff stopped working, so no man-pages.

Comment 6 Ian Ellis 2004-11-10 20:35:36 UTC

To get things working I had to run "fix_libtool_files.sh 3.4.2" (yes, 3.4.2, NOT 3.4.3).  Before running that when I went to compile xine-lib it kept looking for one of the libstdc++ files in one of the old 3.4.2 directories.

Comment 7 nobody 2004-11-19 01:26:10 UTC

Problem comes from that file /etc/env.d/05gcc

Here's how i change it, then -> env-update -> working

this has been resolved in the gcc ebuild

to fix your machine, run `gcc-config <correct chost-ver>`
