 Hello and thanks,

what do you mean "not instantiating the Segment_Delaunay_graph templates parameters properly"? can you explain more.

 

Also the section of segment_delaunay_graph_2.h that has problem is:

template<class Gt,

class ST = Segment_Delaunay_graph_storage_traits_2<Gt>,

class DS = Triangulation_data_structure_2 <

Segment_Delaunay_graph_vertex_base_2<ST>,

Triangulation_face_base_2<Gt> >,

class LTag = Tag_false >

class Segment_Delaunay_graph_2

: private Triangulation_2<

Segment_Delaunay_graph_traits_wrapper_2<Gt>, DS >

{

friend class Segment_Delaunay_graph_hierarchy_2<Gt,ST,Tag_true,DS,LTag>;

friend class Segment_Delaunay_graph_hierarchy_2<Gt,ST,Tag_false,DS,LTag>;

protected:

// LOCAL TYPES

//------------

typedef Segment_Delaunay_graph_2<Gt,ST,DS,LTag> Self;

typedef Segment_Delaunay_graph_traits_wrapper_2<Gt> Modified_traits;

typedef Triangulation_2<Modified_traits,DS> DG;

typedef DG Delaunay_graph;

typedef LTag List_tag;

public:

// PUBLIC TYPES

typedef DS Data_structure;

typedef DS Triangulation_data_structure;

typedef Gt Geom_traits;

typedef ST Storage_traits;

typedef typename Gt::Site_2 Site_2;

typedef typename Gt::Point_2 Point_2;

typedef typename DS::Edge Edge;

typedef typename DS::Vertex_handle Vertex_handle;

typedef typename DS::Face_handle Face_handle;

typedef typename DS::Vertex Vertex;

typedef typename DS::Face Face;

typedef typename DS::size_type size_type;

typedef typename DS::Vertex_circulator Vertex_circulator;

typedef typename DS::Edge_circulator Edge_circulator;

typedef typename DS::Face_circulator Face_circulator;

typedef typename DS::Face_iterator All_faces_iterator;

typedef typename DS::Vertex_iterator All_vertices_iterator;

typedef typename DS::Edge_iterator All_edges_iterator;

typedef typename DG::Finite_faces_iterator Finite_faces_iterator;

typedef typename DG::Finite_vertices_iterator Finite_vertices_iterator;

typedef typename DG::Finite_edges_iterator Finite_edges_iterator;

typedef typename Storage_traits::Point_container Point_container;

typedef typename Storage_traits::Point_handle Point_handle;

typedef typename Storage_traits::const_Point_handle const_Point_handle;

It seems that your are not instantiating the Segment_Delaunay_graph
templates parameters properly. You should at least provide the relevant
lines of code.
