Hello everybody.
I've installed fresh QtCreator and Qt 5.8 to my system. As I understand there are 2 Qt toolchains right now on my PC: One in ~/Qt/5.8 (default path) and one is in usr/lib/x86_64-linux-gnu/qt5/bin where KDE stores it for own purposes. The one in /usr/lib/x86_64-linux-gnu/qt5/bin is version 5.7.

Ok, If I create a dummy project in Qt Creator then it'll allow me to choose only Qt 5.8 Kit. And if I do so I'll get Project ERROR: Unknown module(s) in QT: KF5DBusAddons on any KDE Frameworks module I want to link.

(I'm linking them by QT += KF5DBusAddons in .pro file)
It seems that's because Qt 5.8 don't know about KDE modules in /usr/lib/x86_64-linux-gnu/qt5/mkspecs/modules/ because it looks into ~/Qt/5.8/gcc_64/mkspecs/modules/ instead. And there are no KDE modules. They are not suggested as an option in Qt Online Installer tool.

Fine, so I need either add a Qt5.7 from /usr/lib/x86_64-linux-gnu/ or install KDE Frameworks 5 on top of Qt 5.8. I've tried the first one and run into configuration problems. It still cann't see modules in /usr/lib/x86_64-linux-gnu/.

My question is: Is there a working tutorial on how to start with KDE Framework and Qt Creator. Can I stick with qmake toolchain and not cmake files? Or working explanation on how to add System Qt libraries as a Kit into QtCreator?

P.S. I'm trying to use /usr/lib/x86_64-linux-gnu/qt5/mkspecs/linux-g++-64/qmake.conf And my qmake result command line is qmake /home/user1/dev/kdbustest/kdbustest.pro -spec /usr/lib/x86_64-linux-gnu/qt5/mkspecs/linux-g++-64/ CONFIG+=debug && /usr/bin/make qmake_all

Thank's a lot!

May this help a lot ?

Qt 5.8 is long outdated. The current Qt releases are Qt 5.13 and Qt 5.12 LTS. To develop with KDE Frameworks, the minimum version you need is at least Qt 5.11, but will soon switch to Qt 5.12 when Qt 5.14 gets released in the coming weeks.
