Project ERROR: Unknown module(s) in QT: designer (QT Creator 3.5.1, QT 5.5.1, Linux Mint)
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-*
Problably, it was missing qttools5-dev.
I had this problem also, even with qttools5-designer5 installed.
