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>。请参见此示例。

您缺少必要的include

#include <boost/geometry/geometries/register/point.hpp>
