    Hi,

    The most simple would be to use a URL you have control on so you can point it to your new server.

    @SGaist
    Thank you for your input. You are correct.
    Some components showed up after executing with mirror option. i tried some kind of mirror.
    Downloading stopped several times due to proxy.
    anway, somehow install finished.

    Solved it :) I found the solution in the help text printed when running the windeployqt tool. Using the --qmldir argument added all I needed:

    If your application uses Qt Quick, run: windeployqt --qmldir <path-to-app-qml-files> <path-to-app-binary>

    "method=add" doesn't exist - it looks like the docs are out of date.
    You probably want "method=set"

    @priyankarr
    Absolutely no mention or evidence of "malware" here.
    As with the hundreds of other similar questions about download errors from Qt, start by trying other mirrors.

    @Mihaill Are you trying to download from Russia? It seems so and that's why it isn't working; downloads from Russian IPs are blocked.

    my laptop is MacOS Sonoma system with Apple silicon chip M1
    after I install PyQt6 and the dependencies, I still get the following error message and can not work at all

    qt.qpa.plugin: Could not find the Qt platform plugin "cocoa" in ""
    This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

    I am also trying to build a web engine, but with our NDK, we do not have the required dependencies for the web engine, such as dbus, fontconfig, etc. Could you please share the commands or scripts used to compile fontconfig and nss?

    I tried building fontconfig, but it keeps pointing to another dependency, and this continues. So, any guidance or scripts to streamline this process would be greatly appreciated.

    This message (Could not create scene graph context for backend 'opengl') was caused for me by

    qputenv("QT_QUICK_BACKEND", "opengl");

    When I switched to setting this in the environment variables instead, this message went away.

    @iliahero You should see (in "add/remove components" mode) something like this:
    994d2f4b-e7ab-4f98-941c-e7926a3c6793-image.png
    And from i.e. Qt 6.7.2 tree select those components that might be of interest (you'll need either mingw or msvc version of Qt, source code might be useful, additional components as needed - you can always add later).

    And again to add as well, the plugins folder for this other target is completely skipped.

    Thanks everyone. I believe the problem is caused by linking my app with a third-party library that was itself built with Qt5.

    Hi,

    You also have the option to call the qt-cmake wrapper that can be found in the bin folder of your Qt installation.

    Please start the maintenance tool from the command line, and post the output.
    Looks like you have to select another mirror.
    Check the documentation of the maintenance tool in the internet and find command line options.
