gbWilly GAMBOS reported a new bug. Summary ------- Problem with Gambas upgrade when systems upgrades from qt4 to qt5 (on Debian) Type : Bug Priority : Low Gambas version : 3.8 Product : QT5 component Description ----------- When upgrading a Debain system running qt4 to qt5 gambas3 and gambas3-ide do not upgrade to use qt5, because they insist on using qt4. This problem occured when a Debian jessie system installed with Gambas 3.8.4 got upgraded to Debian stretch (meaning qt4 being replaced by qt5). For details see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=814862 Is this a problem caused by packaging or could this be a problem in Gambas that might pop up in other future distro upgrades as well? If it is something that can be controlled from withing Gambas, would it not be better that gambas preferes qt5 over qt4 for better future upgrades. Now it seems that, because the original Gambas install used qt4, an upgarde to qt5 later on refuses to upgrade gambas3 and gambas3-ide to use qt5. If it has to do with packaging, what steps would the packagers need to do different to make the upgrade work?
