Hey guys..... maybe you should remove the qt3 switch from qt4.......... + Enabled wrapper script usage + Editing "mkspecs/linux-g++/qmake.conf" This is the Qt/X11 Open Source Edition. -no-qt3-support: invalid command-line switch Usage: configure [-prefix <dir>] [-prefix-install] [-bindir <dir>] [-libdir <di r>] Cheers Jean
