Dear Sebastien, thank you very much!

Now it works!

Hello,

The vertex type you are using is for triangulation.
You should use CGAL::Regular_triangulation_vertex_base_2 instead.
Then to add info you can follow what is done for the case of the triangulation of point in
Triangulation_vertex_base_with_info_2.h

Dear Manuel,

thank you for help!

Now I have problem, when I am trying to insert points.
I do it like this:

typedef CGAL::Exact_predicates_inexact_constructions_kernel K;
typedef CGAL::Regular_triangulation_filtered_traits_2<K> Traits;
typedef CGAL::Triangulation_vertex_base_with_info_2<int, K> Vb;
typedef CGAL::Regular_triangulation_face_base_2<K> Fb;
typedef CGAL::Triangulation_data_structure_2<Vb, Fb> Tds;
typedef CGAL::Regular_triangulation_2<Traits, Tds> RegularTr;

       typedef K::Point_2 Point;
typedef RegularTr::Weighted_point WPoint;

       .....

RegularTr T;
WPoint wp(Point(1,2), 2);
T.insert(wp);  // If delete this line - no compiler errors !!!

I tried to modify type of Kernel and way how I define Weighted_point, but it doesn't work
Could you please help me?

       Can you help me, please?
