        @SGaist Good Morning,
        the cod of main is this :

        #include <QCoreApplication>
        #include <QtGui/QApplicationStateChangeEvent>
        #include <QtQml/QQmlApplicationEngine>
        #include <QtWebEngine/qtwebengineglobal.h>
        #include <WebClass.h>
        #include <QtWebChannel/QQmlWebChannel>
        #include <QtWebChannel/qwebchannel.h>
        #include <QtWebEngineWidgets/QtWebEngineWidgets>
        
        int main(int argc, char *argv[])
        {
            QCoreApplication app(argc, argv);
        
        	QtWebEngine::initialize();
        
        	QQmlApplicationEngine engine;
        	engine.load(QUrl(QStringLiteral("main.qml")));
        	return app.exec();
        }
        

        Erros when build :

        /home/gianfranco/Public/QtApplication/QtWebApplicationUbuntu/main.cpp:17: error: undefined reference to `QtWebEngine::initialize()'
        

        I do not understand where the cause is.
        The statements are recognized

        Saluti, Gianfranco Elicat

            Maybe a silly question but did you add QT += webengine to you .pro file ?

                      Hi,

                      Why are you using a QCoreApplication ?
