八叉树更改检测初始值设定项但不完整的类型错误

Question

我正在为我的一个机器人项目浏览PCL库。我正在尝试这个八叉树变化检测程序here。我使用的是PCL1.7。我遵循本教程，当我编译代码时，我得到以下错误

error: variable ‘pcl::octree::OctreePointCloudChangeDetector<pcl::PointXYZ> octree’ has initializer but incomplete type
       pcl::octree::OctreePointCloudChangeDetector<pcl::PointXYZ> octree (resolution);

                                                                                ^

由于这个原因，我得到了其他错误，比如

‘Octree2BufBase’ was not declared in this scope
         LeafContainerT, BranchContainerT, Octree2BufBase<LeafContainerT, Branch

wrong number of template arguments (5, should be at least 1)
 ontainerT, BranchContainerT, Octree2BufBase<LeafContainerT, BranchContainerT> >       

                                                                      ^

 expected ‘{’ before ‘>’ token
 ontainerT, BranchContainerT, Octree2BufBase<LeafContainerT, BranchContainerT> >
                                                                               ^

expected unqualified-id before ‘>’ token

谁能告诉我如何解决这个问题。谢谢！

这是"octree_pointcloud_changedetector.h“中的一个错误，您必须在此文件中添加#include "octree2buf_base.h”。
