qt - QApplication in Visual Studio 2022 console not showing - Stack Overflow

I have a "console" application that depends on a lib which uses QPixmap. Therefore the application crashes if I initialize it with QCoreApplication. So instead I have to use QApplication to initialize the application. I don't even know if this causes my problem. In the Visual Studio 2022 Linker Settings I set the target system to "console" (/subsystem:console) The application starts and everything, but I wanted the console window to show up, so that I can display qInfo() information for the admin in the console. But for any unkown reason the console is'nt showing up. I only get the "Debugger-Console" inside Visual Studio but not the "execution" console.

Does anyone of you know what settings to change to get the console visible?

Using: VS2022 with Qt 6.4.2 x64

The lib (smh) uses QPixmap, for some reason the SmartServ-app will cause a runtime crash when initialized with QCoreApplication, but works fine when initializing with QApplication, just in case this might be reason for the strange behaviour.

• If it's for QPixmap only, you can also use QGuiApplication, as you don't probably need the whole desktop related aspects of QApplication. – musicamante Commented Nov 18, 2024 at 17:28

I found the solution. I was looking up the wrong project configuration. Setting to subsystem:console works just fine.
