Hi. as I have written in the IRC the current troijta can't be build with the current qt creator.
There is a bug which handle the transition from qtwebkit to qtwebengine but it looks like it's not an easy task. https://bugs.kde.org/show_bug.cgi?id=365299 After comment in the #find_package(Qt5WebKitWidgets REQUIRED) I was able to start the build but the first call of #include <QWebPluginFactory> kills the build procees, of course. In file included from D:\Dev\QT-Creator-Projects\trojita\src\Gui\CompleteMessageWidget.cpp:30:0: D:/Dev/QT-Creator-Projects/trojita/src/Gui/EmbeddedWebView.h:25:29: fatal error: QWebPluginFactory: No such file or directory I will now learn qt. Best regards Aleks
