c++ - 无法将结构注册为增强几何3D点

Question

这些声明无法编译

#include <boost/geometry.hpp>

namespace bg = boost::geometry;
struct c3d
{
    double x, y, z;
};
BOOST_GEOMETRY_REGISTER_POINT_3D( c3d, double, bg::cs::cartesian, x, y, z )

编译器输出:

您需要添加#include <boost/geometry/geometries/register/point.hpp>。参见this example。
