Unknown module Qt Multimedia

[U7Development]

Hi!!

I recently updated from 5x to 6.2.0, since my project was using sound effects for clic and bgms, i have incorporated the multimedia module in my project file, after switching to 6.2.0 the issues tab shows:

Project ERROR: Unknown module(s) in QT; multimedia

I know this module was not ready untill 6.2, so, it should load it now isnt?

@U7Development what is your OS?

[U7Development]

thanks for answering..

I'm using Debian 11..

@U7Development 1. Check if in the folder where it is installed this "multimedia", 2. If you are using any IDE (like qtcreator) verify that you have selected the Qt6 kit and not Qt5. Installing Qt6 does not imply removing Qt5, the same applies to Qt6 6.1 and 6.2.

@eyllanesc i recently checked it, and there is no multimedia folder home/Qt/6.2.0/ (libs, include, modules) with no multimedia or qtmultimedia resource...

as a note, while installing Qt, i selected Qt 6.2 for desktop development preset...

@U7Development Start Qt Maintenance Tool and check whether you need to select QtMultimedia to install it (I'm not sure about Qt6, Qt5 contains QtMultimedia by deafult, but this could be different in Qt6).

[U7Development]

@jsulm oh yes, that is, Qt Multimedia was hidden inside additional libraries.


thanks both.

No, it is not inside additional libraries. Windows. Online installer:

@sihnatse Qt Multimedia became a separate library from Qt 6.2, I believe. You've shown a screenshot for Qt 6.1.4. Can. you see it if you expand Qt 6.2.X or higher?

Qt multimedia is in the additionary libraries in QT 6.3.1 :)

@eyllanesc Hi , I face similiar issue when I tried to port the qt application from Qt 5.15 to Qt 6.2.4.
During installation , I have selected Qt Multimedia from the list of additional library. Also I have cross checked it by running MaintenanceTool.

But still I get the error
cannot find the :-1: error: Project ERROR: Unknown module(s) in QT: multimedia

Can you please help to resolve the issue.
