Steps to reproduce the issue

Open source code file cmake file.
Build all projects under 'Release with Debug Information' mode.

Versions

3.39

Supported QGIS version

I'm running a supported QGIS version according to
the roadmap.

New profile

I tried with a new
QGIS profile

Additional context

As for the build kit for QT creator:

Compiler: Visual Studio Enterprise 2022 17.12.35527.113 (amd64)
Debugger: Auto-detected CDB at C:Program Files (x86)\Windows Kits\10\Debuggers\x86\cdb.exe
QT version: Qt 5.15.2 MSVC2019 64bit

@haowong What @ChrisW67 pointed out is you are using Qt5 and Qt6 at the same time. Simply use Qt5 or Qt6, but not both.

@haowong said in When building QGIS source code with QT Creator in windows 10, there are some error LNK2001.:

protected: virtual void __cdecl QToolButton::checkStateSet(void)

It looks like you have a mixture of source code built against Qt 6 but trying to link against Qt 5 libraries.

In Qt 5.15 the protected QToolButton::checkStateSet() is inherited from QAbstractButton and there is no override in QToolButton. In Qt 6.x there is a QToolButton::checkStateSet() override in QToolButton.

Hi sorry for the late reply.
I don't quite understand what you mean, but I feel the simplest solution of your answer is to use QT6 version for building?
And Is there a reasonable solution if QT5 is consistently used?
