I upgraded to KDE 2.2beta1 and tried to compile a KDE application (I also compiled once before the upgrade - it worked fine) and now I get the error: checking for Qt... configure: error: Qt (>= Qt 2.2.2) (libraries) not found. Please check your installation! What do I need to compile this app? I already installed: libqt-dev (2:2.3.0-final-5) - is this the wrong version? The kde development files are already installed... Nik
