用CGAL编译一个简单的测试

我刚刚在mac系统上安装了CGAL和brew。现在我很兴奋地用一个简单而最小的例子来尝试它。我怎样才能用g++编译它?

我想编译这个示例文件:

gcc namefile.cpp -lCGAL -I/usr/local/include/CGAL

和我得到很多错误…(我觉得太多了，不能粘贴在这里)

作为示例文件，我使用

File: examples/Arrangement_on_surface_2/sweep_line.cpp

#include <CGAL/Cartesian.h>
#include <CGAL/MP_Float.h>
#include <CGAL/Quotient.h>
#include <CGAL/Arr_segment_traits_2.h>
#include <CGAL/Sweep_line_2_algorithms.h>
#include <list>
typedef CGAL::Quotient<CGAL::MP_Float>                  NT;
typedef CGAL::Cartesian<NT>                             Kernel;
typedef Kernel::Point_2                                 Point_2;
typedef CGAL::Arr_segment_traits_2<Kernel>              Traits_2;
typedef Traits_2::Curve_2                               Segment_2;
int main()
{
  // Construct the input segments.
  Segment_2 segments[] = {Segment_2 (Point_2 (1, 5), Point_2 (8, 5)),
                          Segment_2 (Point_2 (1, 1), Point_2 (8, 8)),
                          Segment_2 (Point_2 (3, 1), Point_2 (3, 8)),
                          Segment_2 (Point_2 (8, 5), Point_2 (8, 8))};
  // Compute all intersection points.
  std::list<Point_2>     pts;
  CGAL::compute_intersection_points (segments, segments + 4,
                                     std::back_inserter (pts));
  // Print the result.
  std::cout << "Found " << pts.size() << " intersection points: " << std::endl; 
  std::copy (pts.begin(), pts.end(),
             std::ostream_iterator<Point_2>(std::cout, "n"));
  // Compute the non-intersecting sub-segments induced by the input segments.
  std::list<Segment_2>   sub_segs;
  CGAL::compute_subcurves(segments, segments + 4, std::back_inserter(sub_segs));
  std::cout << "Found " << sub_segs.size()
            << " interior-disjoint sub-segments." << std::endl;
  CGAL_assertion (CGAL::do_curves_intersect (segments, segments + 4));
  return 0;
}
