    @SGaist said in QtWebEngine:

    For Visual Studio it goes even further, the different versions of VS are not compatible one with the other except for VS2017 which is backward compatible with VS2015.

    In any case, hover the red icon and see what errors are stated there.

    So does it means that if you install VS2017, you are able to compile with msvc2015 prebuilt component ?

      I have installed VS2017 and QT 5.9.4 on win10 64bit.
      after I have configured qt version same this :
      0_1528905889800_qtversion.jpg

      If I build with X64 is all ok.
      but if I try to use x86 or win32 I have this error

      0_1528906119739_qtversion_error.jpg

      In QT --> Tools --> options I have configured the parameters of compiler :

      0_1528906310453_qtversion_error_2.jpg

      Mabye it's impossible build in 32bit version?

            @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 ?
