Project ERROR: Unknown module(s) in QT: designer (QT Creator 3.5.1, QT 5.5.1, Linux Mint)



  • Hello everyone,
    I'm new with QT. I'm trying to compile in Linux Mint an application previously written for Windows. I get the error

    QtUiPlugin/QDesignerCustomWidgetInterface: No such file or directory
     #include <QtUiPlugin/QDesignerCustomWidgetInterface>
                                                         ^
    

    Then I added to my project file the row

    QT += designer
    

    and I get

    Project ERROR: Unknown module(s) in QT: designer
    

    I installed both QT and QT creator via the official ubuntu repositories, and I made sure of installing libqt5designer5 and libqt5designercomponents5, but I can't get to a solution.
    Does anybody have some suggestions? Thanks.



  • I solved just by installing the qttools via

    sudo apt-get install qttools5-*
