Question

I am trying to do this (directDrawingPainterPath is a class member of type QPainterPath):

directDrawingPainterPath = QPainterPath(point);

However, compiling the program in visual studio gets me the following error:

1>ScribbleWidget.obj : error LNK2019: unresolved external symbol
“__declspec(dllimport) public: class QPainterPath & _cdecl
QPainterPath::operator=(class QPainterPath &&)”
(_imp_??4QPainterPath@@QEAAAEAV0@$$QEAV0@@Z) referenced in function
“protected: virtual void __cdecl ScribbleWidget::mousePressEvent(class
QMouseEvent *)”
(?mousePressEvent@ScribbleWidget@@MEAAXPEAVQMouseEvent@@@Z)

When I rewrite it like this:

QPainterPath tmp(point);
directDrawingPainterPath = tmp;

Then it works. This also happens for other assignments:

This works:

QString tmp = att.value().toString();
name = tmp;

This doesn’t:

name = att.value().toString();

Anyone knows what the problem could be?

Update

I just found the solution: The problem was that I tried to link against a QT that was compiled with VS2008, while I compiled the project with VS2010.

Using a QT that’s also compiled with VS2010 makes everything work…
