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")
