c++ - Macports Cgal不起作用!我如何解决它？

这是我在CGAL主页上找到的基本示例。我正在尝试编译以下内容:

  1 #include <iostream>
  2 #include <CGAL/Exact_predicates_inexact_constructions_kernel.h>
  3 #include <CGAL/convex_hull_2.h>
  4
  5 typedef CGAL::Exact_predicates_inexact_constructions_kernel K;
  6 typedef K::Point_2 Point_2;
  7
  8 int main()
  9 {
 10   Point_2 points[5] = { Point_2(0,0), Point_2(10,0), Point_2(10,10), Point_2(6,5), Point_2(4,1) };
 11   Point_2 result[5];
 12
 13   Point_2 *ptr = CGAL::convex_hull_2( points, points+5, result );
 14   std::cout <<  ptr - result << " points on the convex hull" << std::endl;
 15   return 0;
 16 }

但我得到这个错误:

我使用macports安装了cgal。有谁知道这可能是什么问题
这个？

最佳答案

确实，在构建CGAL和使用CGAL进行编译时，似乎在使用的编译器或编译器选项之间不匹配。可能是Macports没有帮助，安装CGAL时，我对homebrew的使用要比Macports好得多。
