Why no valid kit in Qt Creator

  • Qt Creator claims there is no valid kit. In the maintenance tool, I can see that all the installed elements (Qt version, compiler, ...) are found but there is exclamation mark in front of the Qt Version. Here are the related details of the installed version :

    Name: Qt 5.9.5 in PATH (qt5)

    QT_VERSION 5.9.5

    Linux distribution: Ubuntu 18.04

    Packages that have been installed for the Qt : build-essential, qt5-default qtcreator

    What can I do to solve this ?
    Many thanks. Regards

    Hi @gav007,

    which tooltip do you get if you hover the mouse over the exclamation mark?

  • Hi @aha_1980 ,

    I tried this. There is no tooltip while hovering the mark !


  • I found a workaround : since the auto-detection does not work, the Qt version field was not filled in the Desktop kit. I forced it to the existing Qt version and this kit is now operational and can be selected.

    This does not solve the auto-detection issue ...

    Thanks and regards

    What it be worth to report a bug?
