I think you have the qtchooser syntax wrong. 'man qtchooser' says that the value passed to QT_SELECT is the same as that which would be passed to 'qtchooser -qt='. Testing that, I get: $ qtchooser -qt=4 -print-env QT_SELECT="4" QTTOOLDIR="/usr/lib/x86_64-linux-gnu/qt4/bin" QTLIBDIR="/usr/lib/x86_64-linux-gnu" wanderer@apologia:~$ qtchooser -qt=5 -print-env QT_SELECT="5" QTTOOLDIR="/usr/lib/qt5/bin" QTLIBDIR="/usr/lib/x86_64-linux-gnu" $ QT_SELECT=4 qtchooser -print-env QT_SELECT="4" QTTOOLDIR="/usr/lib/x86_64-linux-gnu/qt4/bin" QTLIBDIR="/usr/lib/x86_64-linux-gnu" IOW: the value you need to pass in is '5', not 'qt5'. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man. -- George Bernard Shaw
