Only Win32 target is supported! And QT Creator layout issue?

[hazbody21]

@Abderrahmene_Rayene @ChrisW67
That was a typo my apologies. I created it with my current OS (Ubuntu 20.04.6 LTS)

@hazbody21 From the errors, It doesn't look like this project you're testing with a clean project.

Could you confirm if the problem still occurs with a new clean project? Just to make sure whether the problem is about the project you're building, or your compiler.

Okay made a blank new project, qmake, qt widgets, here is the compile output:

@hazbody21 said in Only Win32 target is supported! And QT Creator layout issue?:

10 | #include <_mingw_print_push.h>

As you can see your system is still screwed up. Re-install the compiler toolchain and all what depends on it so the correct headers are in /usr/include

[hazbody21]

@Christian-Ehrlicher
I've removed the desktop gcc shown below through the maintenance tool, rebooted, then installed it again. Not sure where else I could've reinstalled.

@hazbody21 said in Only Win32 target is supported! And QT Creator layout issue?:

The Qt installer will not fix your system installation nor install anything in there.
Your complete system is broken - you can't even compile a simple application on the commmand line as soon as you include wchar.h

There is nothing Qt nor a Qt installer can do here. It doesn't even created this.

[CPPUIX]

@hazbody21 Try running this command:

sudo apt-get install --reinstall build-essentials

[hazbody21]

@Abderrahmene_Rayene Thank you for the suggestion, even after a reboot. Still getting the exact same errors.

@Christian-Ehrlicher what suggestions do you have to address this?

[SGaist]

@hazbody21 build-essentials being a meta package you can see that only it was reinstalled not the ones you are looking for. I would uninstall it and all its dependencies and then reinstall it.

[hazbody21]

I got it! I somehow indeed broke the system and reinstalling all the dependencies fixed it:

apt-cache depends build-essential  | grep '[ |]Depends: [^<]' | cut -d: -f2 | tr -d ' ' | xargs sudo apt-get --reinstall install

Thank you @SGaist, @Christian-Ehrlicher, and @Abderrahmene_Rayene
