我设了个点类型，结果出错了，求问原因，求求求！

struct PointXYZRGBI
{
        PCL_ADD_POINT4D;                  // preferred way of adding a XYZ+padding
        float r;
        float g;
        float b;
        float intensity;
        EIGEN_MAKE_ALIGNED_OPERATOR_NEW   // make sure our new allocators are aligned
} EIGEN_ALIGN16;                    // enforce SSE padding for correct memory alignment

POINT_CLOUD_REGISTER_POINT_STRUCT(PointXYZRGBI,           // here we assume a XYZ + "r,g,b,intersity" (as fields)
        (float, x,x)
        (float, y,y)
        (float, z,z)
        (float, r,r)
        (float, g,g)
        (float, b,b)
        (float, intensity, intensity)
)
typedef pcl::PointXYZRGBI PointT;
//////////以上这是定义点
/////结果在运行Octree的函数的时候，出现了连接错误。为什么？是不是因为我的点不在它默认文件里而出现一些问题？
其中一行连接错误是这样写的：
