Did you install the build-essential package ?

[Mucip]

Hi,
sudo apt install build-essential

Already installed...

Then since you seem to want to use clang for your build: install it as well,

Hi,
I could create program finally... :)

But in any case I've got below messages;
22:11:28: Starting /home/milbuga/Documents/Qt/build-untitled-Desktop-Debug/untitled...
qt.qpa.plugin: Could not find the Qt platform plugin "wayland" in ""

Start your application with the QT_DEBUG_PLUGINS environment variable set to 1 to see exactly what is happening.

[Mucip]

Hi,
Should I put
QT_DEBUG_PLUGINS = 1

in pro file?

No, it's an environnement variable.
In Qt Creator, go to the Run part of the Project panel and there you can add it to the list of environment variables.

[Mucip]

Hi,
In this case there is many more errors. :)
I remove line again.

Hi,
As mentioned here below lines are solved my problem without adding environment variable.
sudo apt install libxcb-xinerama0
sudo apt install qt6-wayland
sudo apt install libxcb-xinerama0-dev
sudo apt install qt6-wayland-dev
