Boost几何: assertion_failed误差C++

Question

为了使用boost几何类型，我有以下头文件：

#include <boost/geometry.hpp>
#include <boost/geometry/geometries/point_xy.hpp>
#include <boost/geometry/geometries/polygon.hpp>
#include <boost/geometry/multi/geometries/multi_polygon.hpp>
#include <boost/geometry/geometries/register/point.hpp>

using namespace boost::geometry;
using namespace detail::assign;

typedef model::d2::point_xy<double> point_xy;
typedef model::polygon<point_xy> polygon;
typedef model::multi_polygon<polygon> multi_polygon;
typedef model::box<point_xy> box;

在编译试图使用这些类型的文件时，我会得到一个大量的编译器错误：

我见过这的帖子，其中他们没有注册元组-然而，我没有使用元组或任何特殊类型的点-我只是尝试使用内置的几何类型。为什么这个错误还在发生？

Answer 1

正如您所看到的，发布的代码本身并不是一个问题：住在Coliru。

所以，一定有别的干扰。我有三个预感：

1. 这是你的代码中没有发布的地方。错误的原因是在../src/geometry.cpp中(而不是Boost库)： Assign_points(聚，shape.border)； 这为您提供了关于如何简化为MCVE的好主意。
2. 你有预处理问题。尝试对源代码进行预处理，看看出现在错误消息中的代码是否可疑。 这方面的一个经典示例是，如果其他包含的标头定义了令牌(如#define min(a,b) ...或其他常用的单词)。 附带注意:这是关于代码卫生的。相关的注意事项是using namespace在您所显示的代码片段中的出现。这只会引发名称空间冲突或意外效果。
3. 稍微相关:干扰的来源可能与预编译头有关。尝试禁用这些，或确保您知道PCH头中的内容(特别是在MSVC上(通常使用stdafx.h)，预编译头具有一些潜在的惊人效果)。

更新

我想我注意到了:src/griy.cpp:213:5调用中的违规代码：

assign_points(poly, shape.border);

类型：poly是

boost::geometry::model::polygon<boost::geometry::model::d2::point_xy<double, boost::geometry::cs::cartesian>, true, true, std::vector, std::vector, std::allocator, std::allocator>,

这就是上面所显示的polygon类型。但shape.border是：

std::__1::vector<std::__1::vector<float, std::__1::allocator<float>>, std::__1::allocator<std::__1::vector<float, std::__1::allocator<float>>>>>

那只是vector<std::vector<float> >。那不是支撑几何。
