I am getting MinGW64 compilation error in Qt.

hskoglund

Hi, try to simplify and uninstall/remove as much as possible from your PC:
remove MSVC compiler (run MaintenanceTool and uninstall MSVC)
remove Strawberry
Try to build an example project from Qt 6.3.2 MinGW in Release mode (not Debug). Does it work?

Other thoughts...

Remove the WASM version of Qt also.

Recreate the project definitions:

Close out of Qt creator entirely.
Locate CMakeLists.txt.user in your source directory
Remove or rename it out of the way
Start Qt Creator
Open Project... and select your CMakeLists.txt file.

Build any better?

Do you have more then one CMake installed? Possibly getting confused.

Unfortunately I have other projects that I'm continuing with msvc64. It is not correct for me to remove msvc64. Because my other work is affected. I ran my CMake project, which had this problem, in release mode as you said. The following problems appeared. I don't understand. Thanks.

These error message are because the widget.ui file has not been passed through uic to produce the missing ui_widget.h header and its matching source.

Is widget.ui listed in PROJECT_SOURCES in your CMakeLists.txt file?
Is set(CMAKE_AUTOUIC ON) there?

Does the problem persist if you select Run CMake from the Build menu?

Yeah. There are commands you specified in CMakeList.txt file.

I wonder something. Am I doing something right if I choose CMake as the build system, and run it with msvc64 as well?
I actually tried this, and it worked. But I'm not sure if it's the right thing? this time "Not found in dynamic library!" didn't give an error. It just gave the error that the widget.ui file does not exist in the problems panel. Do you think I did this right? Thanks!!!

Please just post your questions without the @ChrisW67 @JonB @Christian-Ehrlicher @hskoglund stuff every time, allow whichever people to look and answer without calling out every time. Thank you.
