How to solve the error in qrunnable.h?

[Lismoon]

Environment:QT 6.8.0-beta4 +Visual Studio 2022.
I can build my app successfully,but the erorr still shows in visual studio.
it says in D:\Qt\6.8.0\msvc2022_64\include\QtCore\qrunnable.h 24

constexpr QRunnable() noexcept = default;

"defaulted default constructor cannot be constexpr because the corresponding implicitly declared default constructor would not be constexpr”
How can i solve this?It almost drives me crazy!

I don't think you can since it is in Qt code. You can report this on Qt developers mailing list or in Qt bug tracker. But I'm wondering why you're working with a beta version of Qt?

@jsulm
Well..I thought there would be more new features than bugs

In a beta version?

That line has been like that since Qt 6.0 and MSVC 2022 is a tested platform by the CI so the build is not broken.

This must be a problem with OP's system or configuration. Did you apply custom patches? how did you run configure?

@VRonin That was just curious to know why OP uses a beta version.
@Lismoon "I can build my app successfully,but the erorr still shows in visual studio" - if there is an error during the build then your app is not successfully built. Or is it a warning, not error?

Look like it's an intellisense message: https://bugreports.qt.io/browse/QTBUG-85644

Don't worry OP, it happens, it's all good, you can ignore the message. It's a Visual Studio bug, not a Qt one
