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

I am porting code from qt4 to qt5. I added the following line to my .pro file, as suggested:

QT += webkitwidgets

However, when I run qmake, I get the this error:

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

I am developing on Ubuntu 12.04 LTS and installed Qt as described.

Solution

  • You need to install the webkitwidgets library.

    On Ubuntu, try this in a terminal:

    sudo apt-get install libqt5webkit5-dev

    On Fedora, the package has a different name, thus try:

    sudo apt-get install qt5-qtwebkit-devel

    Or on Fedora, via dnf:

    sudo dnf install qt5-qtwebkit-devel
