Hi Rineau,

 

Thank you for making a response.

It should be QT-4.7, not 3.7, right?

I opened the CGAL.sln generated by CMake and was trying to build the whole project. I'm using VS2005, with the operating system WindowsXP SP3.

It doesn't make any difference after the line:

Q_DECLARE_INTERFACE(QGraphicsItem, "com.trolltech.Qt.QGraphicsItem")

added to <QtGui/qgraphicsitem.h>. The Error hint still get printed. 

So, could you point out where the things go wrong?

 

Yan.

CGAL-3.7 can work and hsa been tested with Qt-3.7. The lines you quoted have been added especially to support Qt>=3.6.

I do not know how you can have this error. We need more information. What were you trying to compile? With which compiler? Which compiler version? What is your operating system? Windows, Linux? Which version?

Verify if your file <QtGui/qgraphicsitem.h> contains the following line:

Q_DECLARE_INTERFACE(QGraphicsItem, "com.trolltech.Qt.QGraphicsItem")
