Hello,

Fantastic !

-> It complies now well !

Thank you so much for your help.

See what you wrote:

DT2 is template by kernel *and* TDS. You need to pass a TDS as argument.

I suggest the following:

typedef CGAL::Triangulation_data_structure_2 <
                          CGAL::Triangulation_vertex_base_2<Gt> > TDS;

typedef DT2<Gt, TDS> Tr;

Tr* heritage = new Tr;

Another possibility would have been:

template <class Kernel>
class DT2 : public CGAL::Delaunay_triangulation_2<Kernel> {
 // ...
};

and DT2<Gt>.

The reason is that the second template argument of
CGAL::Delaunay_triangulation_2 has a default value, which is
CGAL::Triangulation_data_structure_2<CGAL::Triangulation_vertex_base_2<Gt> >
