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

[SGaist]

Hi and welcome to devnet,

How did you install Qt ?
Did you also try with your distribution provided Qt ?

@SGaist Hello! Thank you for your reply,
I installed everything using the maintenance tool. I'm not sure what do you mean by distribution provided Qt.

[SGaist]

Ubuntu also provides Qt as well as the corresponding development packages that you can use to develop Qt based applications.

@SGaist
My goal is to use QT to develop GUIs using QT widgets for now, so I need both design studio and creator.
I found a qmake file in "/usr/lib/x86_64-linux-gnu/qt5" I assume that is what you meant, added that to a kit and tried building, here is the compile output:

15:13:45: Running steps for project texteditor...
15:13:45: Starting: "/usr/lib/x86_64-linux-gnu/qt5/bin/qmake" /home/crc/Qt/Examples/Qt-6.3.1/quickcontrols2/texteditor/texteditor.pro -spec linux-g++ CONFIG+=debug CONFIG+=qml_debug

Error while building/deploying project texteditor (kit: Unnamed)
When executing step "qmake"
15:13:45: Elapsed time: 00:00.

The only auto-detected qt is the 6.3.1 I downloaded (see screeenshot)
Reinstalling creator for the 4th or so time fixed the layout issue too:

[SGaist]

Your distribution provided Qt is from the 5 series.

Since you are mentioning widgets only, I don't think you need Qt Design Studio. Or did you mean Designer ?

@SGaist
I also want to use qt quick but that's not an immediate concern now. Yes, it seems it's from the 5 series but that still doesn't build any projects and is throwing the same error thousands of times. I'm not very concerned about the version number as long as I can compile and run GUI projects.

Here is a portion of the end of the compile output:

Which version of gcc did you install ?
What exactly did you install ?

[hazbody21]

@SGaist
All I installed is through the maintenance tool:

[ChrisW67]

@hazbody21 Are you attempting to cross-compile on Linux for Windows using MingW? If not, then the presence of the MingW header in this error message indicates that you have not started from a clean state.

If you take a Qt Creator project from a Windows environment to Linux you:

• Should take the C++ sources and resources and nothing else.
• Do not copy the Qt Creator blah.pro.user file. This is an environment-specific set of QtCreator settings related to the project that needs to be created in each environment.
• Do not copy any pre-compiled header, MOC generated header, or any other compilation output.

[hazbody21]

@ChrisW67
Thank you for replying.
No I'm not doing anything with windows. I'm aware mingw is wrong and tried deleting it but it seems it's not even there:

I have been using an example project that I created on windows ubuntu from the preset examples and still throws the same error. Here is the example application, I deleted blah.pro.user:

Afterwards I started qtcreator and opened the project, attempted to build, here are the first few issues:

here is part of the compile output:

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

I have been using an example project that I created on windows

Could you please try making a new clean project on your current OS and test with it instead? Just to remove all suspicion about imported settings.

[hazbody21]

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

[CPPUIX]

@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.

[hazbody21]

@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?:

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.

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.

@hazbody21 Try running this command:

sudo apt-get install --reinstall build-essentials

@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?

@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.
