    I m using Ubuntu 20. I installed Qt6 and I opened an example to run(simple-cpp). I m getting the error:

    :-1: error: Project ERROR: Unknown module(s) in QT: 3dextras 3dcore 3drender 3dinput
    

    Where does the QtCreator tries to find the modules? I have those modules in the installation folder, how to give the path to those modules?

    @surajj4837 Are those modules installed? Also, keep in mind that Qt6 does not yet have all modules available in Qt5. It is safer for now to use Qt5.

        @surajj4837 This looks like Qt source code...

          In which directory does Qt searches for modules. Following folders exist for 3dcore module in installed directory of Qt.

            In its installation folder.
            How exactly did you install Qt?

                  @surajj4837 According to https://www.kdab.com/qt-3d-changes-in-qt-6/ Qt3D is not provided as binary starting with Qt6. You have to build it by yourself if you want to use it withQt6.

                    @jsulm Thanks for providing the exact solution. Does this page covers the building process?
