i've been using gcc 4.3.4 and recently i fixed my world file and afterwards i did my first: emerge --depclean i checked the list but did not see gcc 4.3.4 (as a removal candidated). so afterwards it was gone and i had only gcc 4.4.4-rc2 installed. as i had no default compiler anymore, there was no gcc and emerge stopped working. so: gcc-config -l [1] x86_64-pc-linux-gnu-4.4.4 gcc-config -f 1 source /etc/profile so i run: fix_libtool_files.sh 4.3.4 afterwards i updated some programs but soon i discovered multiple system failures as for instance: emerge -e world did break for several packages, as: app-accessibility/festival app-accessibility/speech-dispatcher app-text/texlive-core gnome-base/gconf media-gfx/blender media-libs/gegl media-sound/jack-audio-connection-kit media-sound/qjackctl net-im/psimedia x11-libs/libnotify x11-misc/notification-daemon x11-themes/gtk-engines-xfce emerge qt-core (failed): /var/tmp/portage/x11-libs/qt-core-4.6.3/work/qt-everywhere-opensource-src-4.6.3/bin/qmake: /lib/libstdc++.so.6: version `GLIBCXX_3.4.11' not found (required by /var/tmp/portage/x11-libs/qt-core-4.6.3/work/qt-everywhere-opensource-src-4.6.3/bin/qmake) emerge eix (worked, but see runtime) eix -e eix eix: /lib/libstdc++.so.6: version `GLIBCXX_3.4.11' not found (required by eix) # mplayer organpreludecd* (failed at runtime) mplayer: /lib/libstdc++.so.6: version `GLIBCXX_3.4.11' not found (required by /usr/lib/libdirac_encoder.so.0) mplayer: /lib/libstdc++.so.6: version `GLIBCXX_3.4.11' not found (required by /usr/lib/libdirac_decoder.so.0) # konqueror konqueror: /lib/libstdc++.so.6: version `GLIBCXX_3.4.11' not found (required by /usr/lib64/libstreamanalyzer.so.0) konqueror: /lib/libstdc++.so.6: version `GLIBCXX_3.4.11' not found (required by /usr/lib64/libstreams.so.0) i was searching for the issue quite some time. someone from #gentoo-sunrise recommended me to emerge -e system; emerge -e world but afterwards i got even more issues. finally i decided to reinstall the gcc 4.3.4 because i thought the compiler issue could have been caused by just removing gcc 4.3.4 instead of proper upgrading (according to the gcc update manual). after installation of gcc 4.3.4 finished, i changed the compiler, recompiled eix and i was able to use eix! right now i'm recompiling my whole system and later world, with the old compiler gcc 4.3.4 (which works). using gcc 4.4.4-rc2 i produced this: # objdump -T /lib/libstdc++.so.6 | grep GLIBCXX_3.4 | awk '{print $6}' | sort | uniq (GLIBCXX_3.4) GLIBCXX_3.4 GLIBCXX_3.4.1 GLIBCXX_3.4.10 GLIBCXX_3.4.2 GLIBCXX_3.4.3 GLIBCXX_3.4.4 GLIBCXX_3.4.5 GLIBCXX_3.4.6 GLIBCXX_3.4.7 GLIBCXX_3.4.8 GLIBCXX_3.4.9 Reproducible: Always
Seems your system is broken - there should be no such thing as /lib/libstdc++.so.6. libstdc++ resides in /usr/lib/gcc/i686-pc-linux-gnu/<gcc version>/ (well, on x86 it does).
