While building plasma-workspace-4.1.80 (from the kde-crazy Gentoo overlay) I receive thousands of "undefined reference" errors from QFormInternal classes to various QDomNode, QDomDocument, and QDomElement functions. Here's a sample of the last ones:

My Qt version is 4.4.2. I have tried removing and recompiling Qt, but this error persists. I previously built plasma-workspace-4.1.73 on the same system with no problems, but no version has worked since that one. All other kde-4.1.80 packages up to that one build fine (only kdeplasma-addons, kweather, and kdebase-startkde remain).

Since build errors tend to not stay very long, I suspect that the problem is being caused by something specific to my system's configuration, but I'm stumped as to where to look from here.

A build error is not a bug, especially as you are using a build distribution. You should get support from your distribution.

I think it is..

It was partially solved with this patch
http://websvn.kde.org/trunk/KDE/kdebase/workspace/plasma/scriptengines/qtscript/CMakeLists.txt?r1=872339&r2=888087

But it looks like order of libraries is important in this case..${QT_QTUITOOLS_LIBRARY} is static library and has some unresolved symbols provided by ${QT_QTXML_LIBRARY}. If ${QT_QTXML_LIBRARY} occur AFTER ${QT_QTUITOOLS_LIBRARY} than build is OK, otherwise build will fail.

Please reconsider to change the order of libraries to make build distribution users a bit more happy :).

Thanks.
