Not Able to debug or run or do anything with qt creator(No Run Button)

[Yousef Alaa Hussain]

this is my first qt creator project ever made in my new operating system(ubuntu linux) and as you can see, the run buttons are disabled and not clickable, and the error message at the bottom really doesn't allow me to do anything.
i tried to delete this project and recreate other project but doesn't work. is there anything wrong done in the installation or do i need to reinstall qt creator or do i miss anything?

and ye note: "the files in the left side not organized like usual, they usually be organized in a header file folder and source files folder, but this time all in one, i got a warning from the beginning saying that the files not organized well, so they might not work as expected '

as you can see, the application is not understanding the QApplication and QtWidgets at line 3 and 4,
which means i dont have qt installed ?? 🤔

Can you PLEASE not create new threads when you are already asking and being answered in an existing thread? It wastes the time of people like myself trying to help you. I posted what you need to know and do in that thread.

Notice the exclamation mark in your project and the <File System> entry, this means that your project was not Configured by CMake successfully.

You need to paste the content of the General Messages tab, or click on the Issues tab. You have 5 issues there.

How did you install Qt and Qt Creator? Via Ubuntu package manager? If so ... you are most probably missing Qt development packages.

Make sure you have all build tools installed:

$ sudo apt install build-essential cmake ninja-build git

and then the Qt SDK

$ sudo apt install qt6-base-dev qt6-base-private-dev qt6-declarative-dev qt6-declarative-private-dev qt6-tools-dev qt6-tools-private-dev qt6-scxml-dev qt6-documentation-tools libqt6core5compat6-dev qt6-tools-dev-tools qt6-l10n-tools qt6-shader-baker libqt6shadertools6-dev qt6-quick3d-dev qt6-quick3d-dev-tools libqt6svg6-dev libqt6quicktimeline6-dev libqt6serialport6-dev

Note that I took the list of packages from https://wiki.qt.io/Building_Qt_Creator_from_Git_on_Ubuntu_22.04, you might need to install more packages depending on your project's needs.

@JonB I am sorry if I did something was not supposed to happen, but I am new to here, and I am not quite familiar with the rules and what should I do
the problems happened at the same time, that's why I posted them directly after each others
