    @JoeCFD You can simply build qml6sink. Its source code is under /gstreamer/subprojects/gst-plugins-good/ext/qt6. Only a few files.

    @Mesrine said in Cmake recompile qml modules even if the qml files did not change.:

    Is there a way to stop this behavior?

    You have 2 options:

    Use the Ninja generator instead of the Makefile generator (recommended), OR Upgrade to Qt 6.5.2 (see https://bugreports.qt.io/browse/QTBUG-106683 )

    Note that Qt 6.5.2 no longer causes the Makefile generator to rebuild the *.o and *.so files unnecessarily, but there are still other inefficiencies: https://bugreports.qt.io/browse/QTBUG-115166

    @d_h_mcinnes said in Cmake recompile qml modules even if the qml files did not change.:

    I notice that if I build my project from the command line, it rebuilds the .qml files every time. However, if I build from inside qtcreator, it only rebuilds when necessary.

    It sounds like Qt Creator uses the Ninja generator but your command line does not.

    In Client Side:

    You should create a bug report about this. In the meanwhile you can use the qt5compat module - it will not go away until Qt7.

    @Vlogo11 What do you mean you "have the same problem"? What problem do you have? Have you even built your application yet?

    (Because, the fact that you're using a .pro file should be irrelevant, windeployqt is run on the .exe file that results from building your application. Whether you're using CMake or qmake, you need to generate a build system and compile your application before you can do anything with windeployqt.)

    Once you have an application executable, just run windeployqt myapplication.exe on the compiled program. If you don't have any QML then you don't even need to worry about --qmldir at all.

    That's why Qt introduced the qt fixed integer types by themself. the toULong() stuff is an relict from old Qt times and imho should have been replaced a long time ago with functions returning fixed integer types (or the qt fixed integer types).

    Hi and welcome to devnet,

    What exactly are you talking about ?
    How are you sending that request ?
    How are you building it ?
    Which version of Qt are you using ?
    On which platform ?

    Thanks for your message ... yes ... I had installed Ninja v1.11.1 prior to the configuration.
    Got it working by using a locally mounted drive (see below).

    @bebewinla
    As I suggested, the enumerated type namespaces have changed, you need to use the correct ones in PyQt6.

    Also I don't think it's usual to access a enumerated value via self, e.g. like self.ExtendedSelection, I don't know whether Python allows this.

    @jiapei100 check here out about configure settings:

    Just curious: why do you want to build 6.5.1 on Ubuntu 22.04? You can simply install it.

    Hi,

    llvm is used for QDoc to parse and analyse client code. It's not related to the compilation of Qt itself where you can use gcc or clang based on your preference and its availability.

    Hello, All!

    I add Sql to this line:
    target_link_libraries(PrabhupadaDictionary PRIVATE Qt${QT_VERSION_MAJOR}::Widgets Qt${QT_VERSION_MAJOR}::Sql)

    And this problem disappeared. Others appeared. Thanks! I will continue to correct the program "Srila Prabhupada's Dictionary", which was originally written in CopperSpice.

    Thank You very much!
    With best regards, NavadvipaChandra das.
