Qt and Visual Studio 2022?

Question

Qt

Decided to try Visual Studio 2022. I use Qt 6.2.2 version (the package includes qmake for visual studio 2019, but it should work from 2022 according to the description). When I try to run the simplest project (an empty window), I get an error:

Error LNK2019 reference to unresolved external symbol "public: __cdecl QtWidgetsApplication1::QtWidgetsApplication1(class QWidget *)" ([email protected]@[email protected]@@@Z) in function "public: __cdecl `public: static void (__cdecl*__cdecl QtPrivate::QMetaTypeForType::getDefaultCtr(void))(class QtPrivate::QMetaTypeInterface const *,void *)'::`5'::::operator()(class QtPrivate::QMetaTypeInterface const *,void *)const " ([email protected][email protected][email protected]@@@[email protected]@[email protected]@[email protected]@[email protected]@Z). QtWidgetsApplication1 C:\Users\source\repos\QtWidgetsApplication1\QtWidgetsApplication1\moc_QtWidgetsApplication1.obj 1

What could be the reason (using c++20 , debug)

PS in VS 2019 everything was ok

Answer 1

the package includes qmake for visual studio 2019, but should work from 2022 as described

In theory, there is no difference between theory and practice. But in practice there is.
