Hello,
thank you Laurent Rineau for clearing up my confusion about the different versions of QT. Recompiling the CGALQt library did it. Actually, I tried that already, but I must have mixed up my backup libs.
Most of the demos now compile fine. A few still throw errors, but I can live with that.
Thanks again.
Sincerely,
Maik Schulze

I am working with the Microsoft Visual Studio 2005 Professional IDE
under Windows XP. My CGAL version is 3.3.1. All console applications are
compiling fine. Yet, I am not even sure which QT version is supposed to
be used with CGAL.
As Trolltech does not seem to offer QT 3 anymore (at least not for
free)
Trolltech has never offered Qt 3 for Windows (for free). Only Qt-2.3 had a free port for Windows.
, I looked for Q...Windows Edition, which offers an independent implementation at http://qtwin.sourceforge.net/qt3-win32/
I tried to compile the CGAL demos against several versions available at
the sourceforge website. Yet, none works. After converting the .vcproj
to VC8 and changing some minor properties of the project, I get the
following linker errors:
1>CGALQt-vc80-mt-gd.lib(Qt_widget.obj) : error LNK2005: "public:

You need to recompile the CGALQt library, using "Q..3/Windows Free Edition". The CGALQt library shipped with the CGAL installer has been compiled using "Qt-3/Windows Commercial Edition", and is not binary compatible with your version of Qt-3.
If you do not want to recompile CGALQt, you will need to buy a Qt-3 commercial edition (and a CGAL commercial license too).
