After trying to install the pure qtcreator from qt.io website on a new installed Linux VirtualBox machine with a daily build Sabayon KDE version, I was not able to run and build the simple example qtquick man.qml.
So, I don't know, what it's lacking of, I assume, the settings, but how should I know?
So then, thank you for your suggestions, I'm sorry to say, for this time I give it up to try, to use qtcreator.
Thank you anyway for your support, trying to find a solution.
