Kdebase-3.3.2-r2 has exactly the same problem:

Yes, I've been seeing this as well, not quite sure what is going on, it looks like this may have something to do with it: https://bugs.gentoo.org/show_bug.cgi?id=68364
I ended up building kde in a chroot of a stage1 on stage3 dev mothod, and it worked ok

I've been getting this recently too. I did have it successfully merged. Then I wen't to emerge krusader (which failed with the same undefined symbol error). Since then, I've removed qt and kdelibs (to try to get krusader to compile), but now I cannot even get kdelibs to compile! It's very strange.

I'm trying downgrading my glibc to see if that helps. I'll post back if it does.

Here's my emerge info just for kicks:

Recompiling glibc back to an older version didn't help at all.

I'm really curious why this worked the first time, and now it isn't working.

Any more ideas?

EDIT: I notice we're both using gcc-3.4. I'm trying recompiling qt and kdelibs on gcc-3.3.4 right now.

EDIT2: Nope, compiling qt and kdelibs with gcc-3.3.4 didn't solve anything. Kdelibs still breaks.

I found the issue causing this. I turns out the Samsung printer I got this week installed a copy of it's own libqt-mt.so.3.0.4 in /usr/lib. I removed this file, and changed the link to /lib/qt/3/lib/libqt-mt.so.3. I haven't tested if samsung's stuff still works, but now I just got kdelibs and krusader to compile.

So look for a qt lib that was installed by something else, because that fixed it for me.

Oh thank you ! Damn Samsung, I've had this problem for a while now and I've been trying to find out the problem like crazy.
Damn you Samsung ! Although I love the printer and the fact that they actually deliver rerally good drivers

Thanks again,
Georges.

Hey,

I was able to fix the symbol problem by:
$ sudo ln -sf /usr/qt/3/lib/libqt-mt.so.3 /usr/lib/libqt-mt.so.3

Printing works fine but Configurator can't find the scanner.
Restoring the link via:
$ sudo ln -sf libqt-mt.samsung-mfp.so.3.0.4 libqt-mt.so.3
allows Configurator to see the scanner again.

So far, I'm not thrilled with the Samsung software. Why should lpr depend on X just so I can hit the print button? At least make it an option not to display in X. If anyone has found a way around this, please post. [insert diatribe about why I use Linux in the first place...]

I have/had this problem as well. Anything KDE won't compile at all after installing the printer driver. I tired making a symbolic link and as per the posts above and so far I've just made the situation worse. Will uninstalling the printer driver restore my system? Can someone tell me how, I would like to be able to update my system without all the kde libs breaking and then try and reinstall the printer without the samsung software. Basically go back to a state before I installed the printer, and try and work around it replacing this qt file.

All links are fixed but kde compile sometimes failes, cause:

qt leaves : undefined symbol: _ZN5QChar4nullE

qt3 patch included no resolve

Don`t know how to fix for ever, cause, ln -s /usr/qt/3/lib/libqt-mt.so.3 /usr/lib/libqt-mt.so.3
will fixes the problem tempotary, the emerge kde <bla> will compile without probs.
The next emrege kde ebuild to emerge will failes.

Any suggestions,??
