This is unrelated to your problem with "_with_info" classes, though.

Looking at your constrained Delaunay triangulation tag, I assume that you are using an exact constructions kernel, which you cannot do here. You should use an inexact construction kernel, such as 'CGAL::Exact_predicates_inexact_constructions_kernel'.

Note that this also means that you cannot use the tag "Exact_intersections" for your constrained triangulation either (but you can use the exact predicates tag if you use EPICK).

Still does not work. Here is the updated typedefs

typedef CGAL::Delaunay_mesh_vertex_base_2<Kernel, Vb> Vertex_base;

typedef CGAL::Constrained_Delaunay_triangulation_face_base_2<Kernel> Fb;

typedef CGAL::Delaunay_mesh_size_criteria_2< CDTriangulationPlus > Criteria;

typedef CGAL::Delaunay_mesher_2< CDTriangulationPlus, Criteria > Mesher_Base;

typedef CDTriangulationPlus::Vertex_handle Vertex_handle;

typedef std::vector< Vertex_handle > Vertex_handles;

typedef CDTriangulationPlus::Face_handle Face_handle;

This is not the correct approach. Please use the solution that was
provided to you back then.
