<![CDATA[Qt6 on Ubuntu: Unknown modules int Qt: multimedia 3dcore 3dextras 3drender texttospeech 3danimation]]>Hello Fellows!

I developed an application on Windows with Qt6.8.3.
Now I'd like to deploy a Linux version for which I am currently using Ubuntu.
I Installed many components, as on

Unfortunately, when I compile the application in QtCreator on Ubuntu, I get the above errors.

Do you have an advice of how to reliably install these exotic dependencies?

Thanks, best regards

You likely had one selected for which you did not install the extra packages required.

In any case, glad you got it working and good luck :-)

In QtMaintenanceTool, I removed all Versions of Qt und kept Version 6.8.3 only.
In QtCreator, I assigned the right Qt Version under "Preferences->Kits" to the "Desktop" Configuration.
Now, the Linker is fine, and I can focus on code compatibility now :-)

Thanks, have a nice day.

Resolved.

Yes, i use Qt 6.8.3 both on Windows and on Linux.
On Linux, I used the QtMaintenanceTool to install Qt 6.8.3.
Do you know how to install these missing dependencies?

kind regards

Since you seem to have installed a lot of things, are you sure you are using the right Qt version in Qt Creator ?
Did you consider using the Qt version provided by your distribution ?
