Hello,

I am trying to construct the Voronoi diagram of segments via the Voronoi
diagram adaptor. My final goal is to iterate over the faces and the edges of
the Voronoi diagram.

I would like to insert the sites from
/cgal/Segment_Delaunay_graph_2/examples/Segment_Delaunay_graph_2/data/sites2.cin,
but I always get the error "'INSERT_IS_NOT_SUPPORTED' was not declared in
this scope."

This is my code:

typedef CGAL::Quotient<CGAL::MP_Float>  ENT;
typedef CGAL::Simple_cartesian<double>     CK;
typedef CGAL::Simple_cartesian<ENT>        EK;
typedef
CGAL::Segment_Delaunay_graph_filtered_traits_2<CK,CGAL::Field_with_sqrt_tag,
EK,  CGAL::Field_tag>  Gt;
typedef CGAL::Segment_Delaunay_graph_2<Gt>             SDG2;
typedef CGAL::Segment_Delaunay_graph_adaptation_traits_2<SDG2> TRAIT;
typedef
CGAL::Segment_Delaunay_graph_caching_degeneracy_removal_policy_2<SDG2>
POLICY;
typedef CGAL::Voronoi_diagram_2<SDG2,TRAIT,POLICY> SEG_VD;

typedef TRAIT::Site_2 Site_2;
typedef TRAIT::Point_2 Point_2;

My main:

    std::ifstream
ifs("cgal/Segment_Delaunay_graph_2/examples/Segment_Delaunay_graph_2/data/sites2.cin");
    assert( ifs );
    SEG_VD SEG;
    Site_2 site;
    std::vector<Site_2> sites;

    while ( ifs >> site ) { sites.push_back( site ); }
    ifs.close();

    SEG.insert(sites[0]);

The problem seems to be the last line (ie SEG.insert(sites[0]);). Changing
it to SEG.instert(sites[0], CGAL::Tag_true()) produes other errors.

I would be very pleased if someone could help me. To me it seems that I
missed something rather obvious as there are similar examples on this forum
that are supposed to be woking.

Thanks in advance.
