Hi all,
I get a problem in programming of compile. Here is my code, please help me
to resovle it, Thanks a lot!!

-------------------------------------------------------
typedef CGAL::CORE_algebraic_number_traits Nt_traits;
typedef Nt_traits::Rational Rational;
typedef Nt_traits::Algebraic Algebraic;typedef CGAL::Cartesian<Rational>
Rat_kernel;
typedef CGAL::Cartesian<Algebraic> Alg_kernel;
typedef CGAL::Arr_conic_traits_2<Rat_kernel, Alg_kernel,
Nt_traits>Conic_traits_2;
typedef Rat_kernel::Point_2 Point_2;
typedef CGAL::Polygon_2<Rat_kernel> Polygon_2;
typedef CGAL::Gps_traits_2<Conic_traits_2> Gps_traits_2;
typedef Gps_traits_2::Polygon_2 Offset_polygon_2;
typedef Gps_traits_2::Polygon_with_holes_2 Offset_polygon_with_holes_2;
typedef Gps_traits_2::X_monotone_curve_2 X_monotone_curve_2;
typedef Gps_traits_2::Point_2 Query_Point_2;

void main {
             Query_Point_2 pt1(0, 0);
        Query_Point_2 pt2(0, 10);
        Query_Point_2 pt3(10, 0);
        Query_Point_2 pt4(0, 10);
        std::list<Query_Point_2> pts;
        X_monotone_curve_2 is1(pt1, pt2);
        X_monotone_curve_2 is2(pt3, pt4);
        X_monotone_curve_2 iss[] = {is1, is2};

             compute_intersection_points(iss, iss+1, std::back_inserter
(pts));
}
----------------------------------------------------------------
And I got the compil errors as those:
----------------------------------------------------------------
d:\cgal-3.5-beta1\include\cgal\sweep_line_2_algorithms.h(134) : error C2039:
“Traits”: is not a member of “CGAL::Default_arr_traits<Curve>”
.......
etc.....
----------------------------------------------------------------

Please help me on this problem, thanks!!
