c++ - 使用 PCL 的 BreadthFirstIterator 时出现 LNK2001 错误

Question

这是我的代码pcl::octree::OctreePointCloud::BreadthFirstIterator tree_depth_it; pcl::octree::OctreePointCloud::BreadthFirstIterator tree_depth_it_end = octree.breadth_end();

for (tree_depth_it = octree.breadth_begin(); tree_depth_it != tree_depth_it_end; ++tree_depth_it)
{
    if (tree_depth_it.isLeafNode()){...

显示的错误

Error 1 error LNK2001: unresolved external symbol "public: class pcl::octree::OctreeBreadthFirstIterator > & __cdecl pcl::octree::OctreeBreadthFirstIterator >::operator++(void)" (??E?$OctreeBreadthFirstIterator@V?$OctreeBase@VOctreeContainerPointIndices@octree@pcl@@VOctreeContainerEmpty@23@@octree@pcl@@@octree@pcl@@QEAAAEAV012@XZ) C:\Pathe\Octree.obj manipulability_core

当我使用 OctreePointCloudSearch 时没有任何错误，但自从我添加了 BreadthFirstIterator 代码后，错误就会出现。我链接了标准的 pcl_octree_debug.lib，提升了 lib 和 misc pcl 库，但我仍然无法摆脱错误。

显然您需要在代码中插入以下行

#include <pcl/octree/octree_impl.h>

任何使用 PCL 遇到任何 LNK200X 问题的人的引用
