I'm just on the middle of an emerge -uD world. the emerge has come so far as to upgrade my gcc from 3.3.4 to 3.3.5. but, ever since then, I have problems emerging new packages, with typically the following error reported: libtool: link: cannot find the library `/usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.4/libstdc++.la' clearly, there are remaining direct references to gcc 3.3.4 libs. after checking for a while, I found that /etc/env.d/05gcc contained a reference to _both_ 3.3.4 and 3.3.5: LDPATH="/usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.5:/usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.4" which made /etc/ld.so.conf have /usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.4 as well. but removing this by hand isn't enough. it seems that a huge amount of .la files in /usr/lib refer directly to 3.3.4, like the following: # grep "3.3.4" /usr/lib/*.la | head -n 1 /usr/lib/libMagick++.la:dependency_libs=' -L/usr/X11R6/lib -L/usr/lib /usr/lib/libWand.la /usr/lib/libMagick.la -ltiff /usr/lib/libjpeg.la -lXext -lSM -lICE -lX11 -lXt -lbz2 /usr/lib/libltdl.la /usr/lib/libfreetype.la -lz -ldl /usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.4/libstdc++.la -L/usr/i686-pc-linux-gnu/bin -L/usr/i686-pc-linux-gnu/lib -L/usr/lib/gcc-lib/i686-pc-linux-gnu/../../../i686-pc-linux-gnu/lib' this is very annoying. should I really recompile everything, just because I changed my C compiler? or, as a workaround whould I add a symlink: /usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.4 -> /usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.5 ? (this seems an ugly solution) what is more disturing, that visibly, the new gcc also leaves similar, version-specific traces: # grep "3.3.5" /usr/lib/*.la | head -n 1 /usr/lib/libImlib.la:dependency_libs=' /usr/lib/libtiff.la /usr/lib/libjpeg.la /usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.5/libstdc++.la -L/usr/i686-pc-linux-gnu/bin -L/usr/i686-pc-linux-gnu/lib -L/usr/lib/gcc-lib/i686-pc-linux-gnu/../../../i686-pc-linux-gnu/lib /usr/lib/libungif.la -L/usr/X11R6/lib -lX11 -lpng -lz -lm -lSM -lICE -lXext' thus I guess the same problem will come up when upgrading from gcc 3.3.5 to another version... Reproducible: Always Steps to Reproduce: 1. emerge gcc 3.3.4 2. compile a range of packages with it 3. emerge gcc 3.3.5 4. try to compile pages relying on one compiled with 3.3.4 5. see the errors Actual Results: packages relying on libraries compiled with the earlier version of gcc fail to compile (link, actually) Expected Results: migration from gcc 3.3.4 to 3.3.5 should not have any effects on being able to compile packages relying on ones compiled with 3.3.4 # emerge info Portage 2.0.51-r3 (default-linux/x86/2004.0, gcc-3.3.5, glibc-2.3.4.20040808-r1, 2.6.9-gentoo-r4 i686) ================================================================= System uname: 2.6.9-gentoo-r4 i686 Intel(R) Pentium(R) M processor 1.80GHz Gentoo Base System version 1.4.16 distcc 2.16 i686-pc-linux-gnu (protocols 1 and 2) (default port 3632) [disabled]ccache version 2.3 [enabled] Autoconf: sys-devel/autoconf-2.59-r5 Automake: sys-devel/automake-1.8.5-r1 Binutils: sys-devel/binutils-2.15.92.0.2-r1 Headers: sys-kernel/linux26-headers-2.6.8.1-r2 Libtools: sys-devel/libtool-1.5.2-r7 ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CFLAGS="-march=pentium3 -pipe -O3 -fomit-frame-pointer -frename-registers -fprefetch-loop-arrays -falign-functions -mmmx -msse2 -msse" CHOST="i686-pc-linux-gnu" COMPILER="" CONFIG_PROTECT="/etc /usr/X11R6/lib/X11/xkb /usr/kde/2/share/config /usr/kde/3/share/config /usr/lib/mozilla/defaults/pref /usr/share/config /usr/share/texmf/dvipdfm/config/ /usr/share/texmf/dvips/config/ /usr/share/texmf/tex/generic/config/ /usr/share/texmf/tex/platex/config/ /usr/share/texmf/xdvi/ /var/qmail/control"CONFIG_PROTECT_MASK="/etc/gconf /etc/terminfo /etc/env.d" CXXFLAGS="-march=pentium3 -pipe -O3 -fomit-frame-pointer -frename-registers -fprefetch-loop-arrays -falign-functions -mmmx -msse2 -msse" DISTDIR="/usr/portage/distfiles" FEATURES="autoaddcvs autoconfig ccache distlocks sandbox sfperms" GENTOO_MIRRORS="http://128.213.5.34/gentoo/ http://mirror.datapipe.net/gentoo http://mirror.datapipe.net/gentoo ftp://mirrors.sec.informatik.tu-darmstadt.de/gentoo/" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="x86 X aalib acpi acpi4linux alsa apache2 avi berkdb bidi bitmap-fonts bluetooth bonobo canna caps cdr cjk crypt cscope cups curl dga dhcp directfb divx4linux doc dri dvd dvdr encode esd f77 fam fbcon flac flash font-server foomaticdb fortran freewnn gdbm gif gnome gpm gstreamer gtk gtk2 gtkhtml guile imagemagick imlib ipv6 irda jack java javascript jpeg junit libcaca libg++ libwww mad mbox mikmod mmx motif mozcalendar mozilla mpeg mplayer ncurses nls nptl objc odbc oggvorbis opengl opie oss pam pcmcia pda pdflib perl pic png pnp postgres python quicktime radeon readline sdl slang sms speex spell sse sse2 ssl svg svga tcltk tcpd tetex threads tiff truetype truetype-fonts trusted type1-fonts unicode usb v4l v4l2 vawelan wifi wmf xinerama xml xml2 xmms xosd xv xvid zlib video_cards_radeon input_devices_synaptics"
