Please take a look at [0]. I really should write that down on our alioth's web page.

The above will solve the building stage. Now you might hit a problem at runtime. For example, if you call moc, by default Qt4's moc will be used. So you need to somehow tell the system you need the Qt5 version. Take a look at qtchooser's man page, but it basically boils down to either passing -qt5 to each qt-related tool invocation or setting QT_SELECT to Qt5 just to your program (for example, using a script to set the env variable and then calling the binary). We know it's not pretty, but it's what we currently have here. Kinds regards, Lisandro. -- Lisandro Damián Nicanor Pérez Meyer http://perezmeyer.com.ar/ http://perezmeyer.blogspot.com/
