Looks like the triangulation you use has not been instantiated with a
Triangulation_data_structure that has a cell base with info.

Use something like this:

typedef CGAL::Triangulation_3<
          Traits,
          CGAL::Triangulation_data_structure_3<
            CGAL::Triangulation_vertex_base_3< Traits >,
            CGAL::Triangulation_cell_base_with_info_3< MyInfo, Traits >
          >
        > Tr;

Where Traits are the traits you would like to use and MyInfo the type of
the Info.
