Thank you, Changwon.
It seems that there were few other problems when compiling the demo with VC 10.

I think that I've fixed them all.

Attached are 4 patches you will need to apply, some of which fixes the problem above. (Apply the first 2 under the arrangement demo directory and the last 2 under include/CGAL.)

I've also committed the fixes, so that they will be reflected in the next public release.

Hello

I met same problem during CGAL 4.2 demo compilation with visual studio 2010.
solution is
in Arrangement_on_surface_with_history_2.h

  typedef Arrangement_on_surface_with_history_2<Geometry_traits_2,
                                                Base_topology_traits>  Self;
  typedef Self OuterSelf;  //define another Self

---------------
  class Curve_halfedges : public Curve_2,
                          public In_place_list_base<Curve_halfedges>
  {
    friend class Curve_halfedges_observer;
    friend class Arrangement_on_surface_with_history_2<GeomTraits_, TopTraits_>;
    friend class Arr_with_history_accessor<OuterSelf>;

because Self is also defined in base class Curve_2 (it is private)

regards

Hi all,

The demo compiles fine on linux. However, on Windows, VC2010, I have a compilation error (the same in many files):

I do not clearly see where does the problem come from. Do you have any idea, or already succeeded in compiling this demo on windows with vc2010?

Many thanks Laurent, this is exactly what I was looking for!

There must be undocumented code in the Qt4 demo of CGAL arrangements, here:

  demo/Arrangement_on_surface_2
