Hi,

After gcc 4.6.3 was marked stable, I attempted to recompile my entire system (Wasn't necessary really, I just felt like it). Actually 4 of the gentoo boxes I have, 2 of which worked fine, 2 others have this problem. Normally, I have a few packages with problems when I do a world emerge, and I find workarounds.

Unfortunately, this time, I've had a bunch of odd linking problems that I can't seem to resolve.

The problem is typically that a library is missing from the link command line:

Code:
mv -f .deps/gnome_terminal-terminal-window.Tpo .deps/gnome_terminal-terminal-window.Po
/bin/sh ../libtool  --tag=CC   --mode=link x86_64-pc-linux-gnu-gcc -pthread -DORBIT2=1 -I/usr/include/vte-0.0 -I/usr/include/glib-2.0 -I/usr/lib64/glib-2.0/include -I/usr/include/pango-1.0 -I/usr/include/gtk-2.0 -I/usr/include/gio-unix-2.0/ -I/usr/include/cairo -I/usr/lib64/gtk-2.0/include -I/usr/include/atk-1.0 -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/pixman-1 -I/usr/include/freetype2 -I/usr/include/libpng15 -I/usr/include/libdrm -I/usr/include/gconf/2 -I/usr/include/orbit-2.0   -Wall -Wmissing-prototypes -Wnested-externs -Wpointer-arith -Wno-sign-compare    -O2 -march=native -pipe  -Wl,-O1 -Wl,--as-needed -o gnome-terminal gnome_terminal-eggshell.o gnome_terminal-profile-editor.o gnome_terminal-terminal.o gnome_terminal-terminal-accels.o gnome_terminal-terminal-app.o gnome_terminal-terminal-debug.o gnome_terminal-terminal-encoding.o gnome_terminal-terminal-info-bar.o gnome_terminal-terminal-options.o gnome_terminal-terminal-profile.o gnome_terminal-terminal-screen.o gnome_terminal-terminal-screen-container.o gnome_terminal-terminal-search-dialog.o gnome_terminal-terminal-tab-label.o gnome_terminal-terminal-tabs-menu.o gnome_terminal-terminal-util.o gnome_terminal-terminal-window.o  gnome_terminal-skey-popup.o  gnome_terminal-eggsmclient.o  gnome_terminal-eggdesktopfile.o gnome_terminal-eggsmclient-xsmp.o    gnome_terminal-terminal-marshal.o gnome_terminal-terminal-type-builtins.o  skey/libskey.la -pthread -lvte -lgthread-2.0 -lrt -lgtk-x11-2.0 -lgdk-x11-2.0 -latk-1.0 -lgio-2.0 -lpangoft2-1.0 -lpangocairo-1.0 -lgdk_pixbuf-2.0 -lcairo -lpango-1.0 -lfreetype -lfontconfig -lgobject-2.0 -lgconf-2 -lglib-2.0 -lX11   -lSM

Same package works fine on a different box. I tried rebuilding x11-libs/libICE, of course. I have several other packages that can't find libm.so or
libgmodule.so, libXau.so, libpthread.so.0. Same symptoms, different libraries.

Meanwhile on other boxes this package works fine. Sometimes unmasking a later revision helped. For the others, I'm thinking of moving them to my overlay to see if I can "fix" them . Searching the forums and google, I've found other people who had similar errors, but I haven't found what causes this.

Anyway, any hints or ideas you can provide would be appreciated. At this point, I hope it's something stupid I did, if it lets me move on from these build errors.

This one is especially fun because I can clearly see -lXau on the libtool command line but it still doesn't seem to find the XauFileName symbol. Perhaps it needs to be referenced earlier in the link.

Switching back to gcc 4.5.4 had no effect. Still researching this.

EDIT: It appears that having LD_LIBRARY_PATH set in /root/.bashrc was the source of these problems. It took a surprisingly long time to notice this was only set on the boxes with failing compiles. So it wasn't related to gcc. I have had that variable set for a long time without problems, so I am not sure why it's a problem now.
