Hi,
I am trying to compile Alpha_shape_2 using Periodic_Delaunay_Triangulation_2. Here is code I use:

// CGAL headers
#include <CGAL/Exact_predicates_exact_constructions_kernel.h>
#include <CGAL/Periodic_2_triangulation_filtered_traits_2.h>
#include <CGAL/Periodic_2_Delaunay_triangulation_2.h>
#include <CGAL/Triangulation_vertex_base_with_info_2.h>
#include <CGAL/Alpha_shape_2.h>

//Typedefs
typedef CGAL::Exact_predicates_exact_constructions_kernel K;
typedef CGAL::Periodic_2_triangulation_traits_2<K> GT;
typedef CGAL::Periodic_2_triangulation_vertex_base_2<GT>    Vb;
typedef CGAL::Triangulation_vertex_base_with_info_2<unsigned, GT, Vb> Vb_info;
typedef CGAL::Periodic_2_triangulation_face_base_2<GT>      Fb;
typedef CGAL::Triangulation_data_structure_2<Vb_info, Fb>    Tds;
typedef CGAL::Periodic_2_Delaunay_triangulation_2<GT, Tds>  PDT;
typedef PDT::Point   Point;
typedef PDT::Point                                  Point_2;

typedef CGAL::Alpha_shape_2<PDT> Alpha_shape_2;

When I try to initialize Alpha_shape_2 object I get errors listed below. Any idea if what I'm trying to do is possible?
Best,
Grzegorz
