最新版本的升压和升压几何库（GGL）之间的冲突

Question

过去，我使用库GGL来编写一些程序。例如，下面的代码适用于GGL和旧版本的gcc。现在我将gcc更新到gcc4.7.1。我的程序在编译期间出现错误。因此，我更新到boost 1.52.1的最新版本。仍然存在与point_2d，polygon_2d等相关的错误。我发现在最新的vesion boost中缺少一些像'cartesian2d.hpp'，'c_array_cartesian.hpp'这样的文件。

有人可以帮我分析下面的代码，并告诉我有什么问题吗？非常感谢。

#include <iostream> 

#include <boost/geometry.hpp> 
#include <boost/geometry/geometries/point_xy.hpp> 
#include <boost/geometry/geometries/polygon.hpp> 
#include <boost/geometry/algorithms/distance.hpp> 
#include <boost/geometry/geometry.hpp> 

#include <algorithm> // for reverse, unique 
#include <iostream> 
#include <string> 


typedef boost::geometry::model::d2::point_xy<double,   
boost::geometry::cs::cartesian> point_2d; 
typedef boost::geometry::model::polygon<point_2d> polygon_2d; 
using namespace boost::geometry; 

int main() { 
     std::cout << "!!!Hello World!!!" << std::endl; // prints !!!Hello World!!! 
     model::d2::point_xy<int> p1(1.0, 1.0), p2(2.0, 2.0); 
     point_2d x(3.0,3.0); 
     std::cout << x.x(); 
     std::cout << "Distance p1-p2 is: " << distance(p1, p2) <<std::endl; 

     float width = 100; 
     float length = 100; 


     polygon_2d poly; 
     { 
      const float coor[][2] = { 
      {-350.0,-500.0}, {350,-500}, {350, 0}, {width/2.0, 0}, {width/2.0, length}, 
      {350, length}, {350, 1000}, {-350, 1000}, {-350, length}, {-1*width/2.0, length}, {-1*width/2.0,0}, 
      {-350, 0}, {-350.0,-500.0} // closing point is opening point 
      }; 
      assign(poly, coor); 
     } 
      correct(poly); 

     return 0; 
} 

的误差如下：

Answer 1

两个变化是必要的：

1）包括c_array.hpp，到2D浮子阵列（const的浮子内部使用适应[] [2]）到Boost.Geometry Point概念：

#include <boost/geometry/geometries/adapted/c_array.hpp> 

2）使用assign_points而不是assign。

assign_points(poly, coor); 

然后编码您的代码。背景：您使用的是预发布版本（当然是允许的），发布版在界面中进行了小的更改。分配（带范围）现在称为assign_points。
