My app in Qt 5.7, Windows 7, 64 bit-compile crashed in d3d11sdklayers.dll

  • I create an app on Windows 7, compiled as 32 bit, and it runs fine. However when I switch everything to 64 bit, the app could not run. It crash in d3d11sdklayers.dll. Here is the stack trace:

    In EMnetXClient it crashes right at
    QQmlContext*rootContext = engine.rootContext();

    Any clue?

    Could you provide a little bit of your code surrounding line 169 in main()?

    Kind regards.

  • QQmlApplicationEngine engine;
        QQmlContext*rootContext = engine.rootContext(); // <<< Crash here
        rootContext->setContextProperty("deviceID", QVariant::fromValue(g_config.queueName()));
        rootContext->setContextProperty("webSiteURL", QVariant::fromValue(g_config.websiteUrl()));
        return app.exec();

    The initTrayIcon function:

    void initTrayIcon(QQmlApplicationEngine &engine)
        QObject *root = 0;
        if (engine.rootObjects().size() > 0)
            root = engine.rootObjects().at(0);
            QAction *minimizeAction = new QAction(QObject::tr("Mi&nimize"), root);
            root->connect(minimizeAction, SIGNAL(triggered()), root, SLOT(hide()));
            QAction *maximizeAction = new QAction(QObject::tr("Ma&ximize"), root);
            root->connect(maximizeAction, SIGNAL(triggered()), root, SLOT(showMaximized()));
            QAction *restoreAction = new QAction(QObject::tr("&Restore"), root);
            root->connect(restoreAction, SIGNAL(triggered()), root, SLOT(showNormal()));
            QAction *quitAction = new QAction(QObject::tr("&Quit"), root);
            root->connect(quitAction, SIGNAL(triggered()), qApp, SLOT(quit()));
            QMenu *trayIconMenu = new QMenu();
            QSystemTrayIcon *trayIcon = new QSystemTrayIcon(root);

  • Hi, if you compile in Release mode does it still crash the same way?

  • @kshegunov I check the the debug log in the 32 bit version, and I think there is something relate to it. The line 168 " QtWebEngine::initialize();" is actually show a warning
    D3D11: ERROR: ID3D11Device::CheckFormatSupport: Format (null) is not available at the current FeatureLevel. [ MISCELLANEOUS ERROR #2097402: CHECKFORMATSUPPORT_FORMAT_NOT_SUPPORTED ]

    This is actually the culprit that crash the app in 64 bit version. I step thru the code in 64bit, and at that location, I got an access violation. The next line (169) will stop the app.

  • @hskoglund Interesting... the release version of 64bit does not!
    How so!!?

  • Qt Champions 2017

    From what I can tell from your code you aren't doing anything wrong. Obviously there's some problem with initializing direct 3D, but what exactly causes this I don't know, sorry.

    Kind regards.

  • @TonyN

    Hi, TonyN
    Have you solved it? I have the same problem.

  • @zhong-san No, I submitted a bug report and was accepted, but it still not resolve yet

  • I end up used a different graphic board. The driver for Intel HD 3000 just buggy and they end support on 2015!. I don't know how to get around this with old computer from customers yet
