Installation and Deployment

I'm using this script https://github.com/olegantonyan/mpz/blob/master/win/dynamic_win64_qt6_host.sh to build binaries for Windows (Win10 host in VirtualBox, MinGW11, run script in Git bash)
It works with Qt 5 and Qt 6.3.1, but with Qt 6.4.0 resulting binary silently exists upon launch:user@DESKTOP-RKU7FJS MINGW64 ~/Desktop/mpz-1.0.21-win64-qt6-dynamic $ ./mpz.exe user@DESKTOP-RKU7FJS MINGW64 ~/Desktop/mpz-1.0.21-win64-qt6-dynamic $ echo $? 127strace:

What's wrong here?

Hi, welcome to the forum.
Start your app in Creator under debugger and open the modules window (View->Views->Modules). Sort by module path column and see what dlls are loaded (ignore the ones from System32). See if all of them are present in your app directory after windeployqt runs.
You can also open your exe in Dependencies. It will tell you if any dependent dlls can't be found.

Thank you, Chris,
E:\Qt\6.4.0\mingw_64\plugins\multimedia\windowsmediaplugin.dllseems missing. So I copiedplugins/multimedia/into deployed folder and now it works. But whywindeployqtdoesn't do this? And why this wasn't the problem in Qt 6.3? I've checked old releases - there's nopluginsdir and they work fine.btw https://github.com/lucasg/Dependencies app doesn't launch either

But why windeployqt doesn't do this?
I don't know, apparently some dependency chain changed. Are you actually using anything from the multimedia module?
In any case you can force windeployqt to copy multimedia plugin via command line options.btw https://github.com/lucasg/Dependencies app doesn't launch either
Dependencies.exe is a command line tool. Run DependenciesGui.exe for a graphical interface.

Yes, I'm using QtMultimedia - it's audio player so multimedia is a core functionality.
It seems likewindowsmediaplugin.dllis not linked dynamically to the binary, but loaded at runtime via dlopen or whatever similar on Windows.
In any case you can force windeployqt to copy multimedia plugin via command line options.
How? I see
--no-pluginsoption, but nothing related to explicit copy of plugins
Simplecp -Rworks though, but it's kind of a hack -
How? I see --no-plugins option, but nothing related to explicit copy of plugins
The help says to just pass the name of the module, so
-multimedia.
