Hm, the link command doesn't seem to include -lm or -ldl, maybe that has something to do with the missing symbols...
It is much more likely that it has something to do with gold linker that OP mentioned. I already need to have few files like this: > $ cat /etc/portage/env/media-gfx/gimp-2.6.7 > # fix for gold linker > LDFLAGS="-lglib-2.0 -lgobject-2.0 -lm" I looks to me like gold is in some cases dropping/ignoring some transitive dependencies from libs, where original linker respects them. But I haven't investigated it too deep yet, I'm trying to rebuild system with gold first and see if it disappears when all files are linked by same linker (atm nvidia-settings fail for me with binutils-1.20[gold] too).

(In reply to comment #5) > Same problem, binutils-1.20 WITHOUT gold. That is NOT the same problem. prev_error_handler is a function-pointer declared in NvCtrlAttributesVidMode.c, it is an internal symbol. "pow" "dlopen" etc. are external symbols lying in libm and libdl. What i don't like is this: ### src/libXNVCtrlAttributes/NvCtrlAttributesVidMode.c:195:2: warning: #warning Old xf86vmode.h; dynamic gamma ramp support will not be compiled. ### That is the problem, as ### #if defined(X_XF86VidModeGetGammaRampSize) <---- LOOK HERE!!! /* * XXX The XF86VidMode extension can block remote clients. * Unfortunately, there doesn't seem to be a good way to determine if * we're blocked or not.

Also have a look at the comment below the "if defined". Which versions of x11-libs/libXxf86vm and x11-proto/xf86vidmodeproto do you have installed? BTW: I did a complete rebuild of my system after upgrading GCC from 4.3 to 4.4, with binutils[gold], and i get this error.
I have same issues. The current version of libXx86vm is 1.1.0 and xf86vidmodeproto is 2.3
Missing symbols during _compilation_ is duplicate of bug #289744 and is caused by new libXxf86vm. I did some cleaner test case to confirm that gold is the culprit. With patch for libXxf86vm from that bug in local overlay: $ ld -v GNU ld (GNU Binutils) 2.20 $ emerge -1 =nvidia-settings-190.42 (no error) $ ld -v GNU gold (GNU Binutils 2.20) 1.9 $ emerge -1 =nvidia-settings-190.42 ... /usr/lib/gcc/x86_64-pc-linux-gnu/4.4.2/../../../../x86_64-pc-linux-gnu/bin/ld: .objs/NvCtrlAttributesVidMode.o: in function NvCtrlSetColorAttributes:NvCtrlAttributesVidMode.c(.text+0x4b7): error: undefined reference to 'pow' /usr/lib/gcc/x86_64-pc-linux-gnu/4.4.2/../../../../x86_64-pc-linux-gnu/bin/ld: .objs/NvCtrlAttributesXv.o: in function NvCtrlXvAttributesClose:NvCtrlAttributesXv.c(.text+0x333): error: undefined reference to 'dlclose' (... more link errors ...) $ echo 'LDFLAGS="-lm -ldl"' >> /etc/portage/env/media-video/nvidia-settings-190.42 $ emerge -1 =nvidia-settings-190.42 (no error again)
x11-proto/xf86vidmodeproto-2.3 x11-libs/libXxf86vm-1.1.0 Didn't realize its a different error. I'll try rebuild world and see what happens.
with x11-proto/xf86vidmodeproto-2.3 x11-libs/libXxf86vm-1.1.0 same errors
Yet another bug with 2 mixed issues. The header bug was fixed, sync in a hour. But the USE=gold and linking issue remains unsolved.

I've got them fixed by editing src/libXNVCtrlAttributes/NvCtrlAttributesVidMode.c and added after #include <X11/extensions/xf86vmode.h> the line #include <X11/extensions/xf86vmproto.h> now they compiles fine.
Here are my steps to install ebuild /usr/portage/media-video/nvidia-settings/nvidia-settings-180.60.ebuild configure edit /var/tmp/portage/media-video/nvidia-settings-180.60/work/nvidia-settings-1.0/src/libXNVCtrlAttributes/NvCtrlAttributesVidMode.c like my previous post ebuild /usr/portage/media-video/nvidia-settings/nvidia-settings-180.60.ebuild compile install qmerge

Comment on attachment 247594 [details] ebuild for Stefan Oswald patch for 173 branch this bug report has nothing to do with these missing X symbols. file a new bug.
if the main nvidia-settings prog needs libm/libdl/etc..., it must link directly against those libraries. if it links against some other lib which happens to link against libm/libdl, that is not sufficient.
19x.xx doesn't exist anymore, all others should build fine now, please re-open in case I am wrong.
