Hi,

Which version of Qt 6 are you using ?
On which version of Windows ?

Do additional files also fail to register?
If you remove one existing file does it still fail?

I just tried replacing the Qt dlls with 5.15.2 dll and it seems to have resolved itself. I only had the binaries for 5.14.2 so I was unable to jump into the QApplication code. Issue is resolved, thanks for the reply.

@SGaist said in Interslavic language for translations:

Do you mean translate your application for it or have a translation for Qt itself ?

Language in the list of languages ​​for translation in Qt Creator or Qt Linguist project.

Hi,

If you leave the QOpenGLXYZ classes, widgets are not hardware accelerated.
Since it's a hobby project, I would encourage you to do some tests to learn from the tech to decide which one fits best.

One thing to take into account is that the Qt3D module is being deprecated in favor of QtQuick 3D.

What do you mean by "hardware 3D graphics" ?

I was able to fix it (at least on the systems we use for testing) by setting the QVTKOpenGLNativeWidget::defaultFormat() format profile to QSurfaceFormat::CoreProfile instead of QSurfaceFormat::CompatibilityProfile. This seems a bit counter intuitive, since it appears to be more compatible, but I'm happy nevertheless...

auto format = QVTKOpenGLNativeWidget::defaultFormat();
format.setProfile(QSurfaceFormat::CoreProfile);
QSurfaceFormat::setDefaultFormat(format);

(Also I did try this in a qmake project and it was successful so the issue I am facing may be peculiar to CMake-based projects.)

The fact that you are using the open source sources does not change my initial suggestion: you have a commercial license so you can request the Qt Company's help.

Do you have multiple versions of libstdc++ in your sysroot ?

On a side note, your thread title is misleading, you haven't even reached webengine yet in your build.

See https://doc.qt.io/qt-6/qtcharts-changes-qt6.html

@jsulm The compilation is now stuck in the image below.

What can I do?

You should use a debugger to see where it really crashes and if you can reproduce it, create a minimal, compilable example so we can also take a look on it.

Though that page doesn't show any QML examples as far as I can see.

I recall having to try a few things when I first wanted to do this a few years ago. I don't know if what I arrived at is the "correct" approach, but the format that I found to work in QML and have stuck to ever since involves using a triple forward slash like this:

source: "qrc:///images/my-image.png"
