Yo, compiling kde-support r956756 fails. I'm using qtcopy. The log: ~/src/qt/include/QtCore/qhash.h: In member function ‘typename QHash::Node** QHash::findNode(const Key&, uint*)$ ~/src/qt/include/QtCore/qhash.h:723: instantiated from ‘T& QHash::operator[](const Key&) [with Key = QUrl, T = Sopra$ ~/src/kde/kdesupport/akonadi/server/src/search/result.cpp:88: instantiated from here ~/src/qt/include/QtCore/qhash.h:858: error: no matching function for call to ‘qHash(const QUrl&)’ Note that as of Qt4.5 the API contains no QUrl overload for qHash (although there are a few "static inline" internal implementations). Googling turns up a couple of old discussions about kdebase not building: http://mail.kde.org/pipermail/kde-dashboard/2009-January/013322.html http://forum.kde.org/kdebase-is-not-compiling-anymore-t-28578.html Can you suggest a course of action? - Stefan // cc me please
