Hi,

I added this code. But it did not work. I am relatively new to CGAL. Please help.

typedef CGAL::Triangulation_ds_face_base_with_info_2<Index, Gt> Info;

Hi,

When i run the following to create Delanuay Triangulation and index of the vertices,
Following error occurs.
error C2039: 'info' : is not a member of 'CGAL::Triangulation_ds_face_base_2<TDS>'

The error is explicit:

no info is in Triangulation_ds_face_base_2. So you need to use Triangulation_ds_face_base_with_info_2.

I am new to CGAL. Please help
