Hi,

Well, install Qt Creator with the package manager from your distribution. Since it's Debian: apt-get install qtcreator.

Mucip

Hi,
I am installing now.

Hi,
I used many times QT in RP. But It was not difficult as now unfortunately.
I installed QtCreator and open. I created very basic project but could not run even?!
Message:
:-1: error: Cannot run compiler 'clang++'. Output:

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,

Mucip

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 ""
QStandardPaths: wrong permissions on runtime directory /run/user/1000, 0770 instead of 0700

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.

Mucip

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
