QGuiApplication: No such file or directory

embdev

Dear fellow coders, i'm trying to use my own kit to build an exe file using the example 'clocks' in Qt examples but was unsuccessful.

Under [Issues] window says: 'QGuiApplication: no such file or directory'

Is there anything wrong with my Kit's qmake.exe file? When I use the default GCC desktop kit, the program compiles and run successfully.

Which version of Qt ?!

Check your .pro file you need to add QT += widgets in the .pro file after that run qmake once and use #include <QApplication> instead of #include <QtGui/QApplication>

let me check my Qt installation again.

embdev

Hi @Kambiz mbiz & @jsulm , aft added QT += widgets and using <QApplication>, the next error is "QQmlengine: No such file or directory" The following is a sample code from Clocks example, built on Qt Quick.

#include <QDir>
//#include <QGuiApplication>
#include <QApplication>
#include <QQmlEngine>
#include <QQmlFileSelector>
#include <QQuickView> //Not using QQmlApplicationEngine because many examples don't have a Window{}
#define DECLARATIVE_EXAMPLE_MAIN(NAME) int main(int argc, char* argv[]) \
{\
    QGuiApplication app(argc,argv);\
    app.setOrganizationName("QtProject");\
    app.setOrganizationDomain("qt-project.org");\
    app.setApplicationName(QFileInfo(app.applicationFilePath()).baseName());\
    QQuickView view;\
    if (qgetenv("QT_QUICK_CORE_PROFILE").toInt()) {\
        QSurfaceFormat f = view.format();\
        f.setProfile(QSurfaceFormat::CoreProfile);\
        f.setVersion(4, 4);\
        view.setFormat(f);\
    }\
    view.connect(view.engine(), SIGNAL(quit()), &app, SLOT(quit()));\
    new QQmlFileSelector(view.engine(), &view);\
    view.setSource(QUrl("qrc:///" #NAME ".qml")); \
    view.setResizeMode(QQuickView::SizeRootObjectToView);\
    if (QGuiApplication::platformName() == QLatin1String("qnx") || \
          QGuiApplication::platformName() == QLatin1String("eglfs")) {\
        view.showFullScreen();\
    } else {\
        view.show();\
    }\
    return app.exec();\
}

@embdev said in QGuiApplication: No such file or directory:

QQmlEngine

Well, if you check the Qt documentation for QQmlEngine you will find out what you need to do :
QT += qml
