错误LNK2001当包括“pcl_visualizer.h” [英] error LNK2001 when including "pcl_visualizer.h"

问题描述

我想使用点云库来可视化点云。我已经包括：

  #include< pcl / point_types.h> 
 #include< pcl / io / pcd_io.h> 
 #include< pcl / kdtree / kdtree_flann.h> 
 #include< pcl / features / normal_3d.h> 
 #include< pcl / surface / gp3.h> 
  

没有任何问题，但是当我添加

  #include< pcl / visualization / pcl_visualizer.h> 
  

给我的代码我收到LNK2001错误。

Fehler 51错误LNK2001：Nichtaufgelöstesexternes符号public：virtual void __cdecl pcl :: visualization :: PCLVisualizer :: FPSCallback :: Execute（class vtkObject *，unsigned long，void *） （？执行@ FPSCallback @ PCLVisualizer @ visualization @ pcl @@ UEAAXPEAVvtkObject @@ KPEAX @ Z）

我认为有一个图书馆缺失但我无法弄明白哪一个。这是与我的程序的附加依赖关系的列表：

• pcl_common_debug.lib


• pcl_io_debug。 lib


• pcl_kdtree_debug.lib


• pcl_features_debug.lib


• pcl_surface_debug.lib


• pcl_search_debug.lib


• pcl_visualization_debug.lib


• vtkCommonCore-6.1.lib


• vtksys- 6.1.lib


• 和一些opencv库

任何人都可以告诉我哪个图书馆缺少？

提前感谢

编辑：

我基于greedy_projection.cpp代码创建了一个小型的cpp文件。感谢drescherjm的建议，我使用了cmake来创建项目，我可以编译没有错误。然后我想把这些东西放在我的另一个项目中，但发生同样的错误。
现在我发现错误的原因是\clr标志。我有一个Windows.Forms项目，所以它是用\clr编译的。 greedy_projection.cpp项目编译时没有这个标志。有没有什么办法避免与\clr的pcl_visualizer.h的不兼容？

解决方案

我可以解决问题！ p>

我刚刚评论了

  struct FPSCallback：public vtkCommand 
  

pcl / visualization / pcl_visualizer.h的功能。然后一切都很好。我不需要FPSCallback，所以它是一个完美的解决方案，我运行我的代码与\clr支持。

感谢drescherjm的帮助!!

I want to visualize a point cloud using the point-cloud-library. I already included:

#include <pcl/point_types.h>
#include <pcl/io/pcd_io.h>
#include <pcl/kdtree/kdtree_flann.h>
#include <pcl/features/normal_3d.h>
#include <pcl/surface/gp3.h>

without any problem, but when I add

#include <pcl/visualization/pcl_visualizer.h>

to my code I receive an LNK2001 error.

Fehler 51 error LNK2001: Nicht aufgelöstes externes Symbol ""public: virtual void __cdecl pcl::visualization::PCLVisualizer::FPSCallback::Execute(class vtkObject *,unsigned long,void *)" (?Execute@FPSCallback@PCLVisualizer@visualization@pcl@@UEAAXPEAVvtkObject@@KPEAX@Z)"

I think there is a library missing but I can't figure out which one. This is the list with the additional dependencies of my program:

• pcl_common_debug.lib
• pcl_io_debug.lib
• pcl_kdtree_debug.lib
• pcl_features_debug.lib
• pcl_surface_debug.lib
• pcl_search_debug.lib
• pcl_visualization_debug.lib
• vtkCommonCore-6.1.lib
• vtksys-6.1.lib
• and some opencv libs

can anyone tell me which library is missing?

Thanks in advance!

edit:

I created a little cpp-file based on the greedy_projection.cpp code. Thanks to the advice of drescherjm, I used cmake to create the project and I could compile it without errors. Then I wanted to include the stuff in my other project but the same error occurred. Now I figured out, that the reason for the error is the \clr flag. I have a Windows.Forms Project so it is compiled with \clr. The greedy_projection.cpp Project was compiled without this flag. Is there any way to avoid this incompatibility of pcl_visualizer.h with \clr?

解决方案

I could solve the issue!

I just commented the code inside of the

struct FPSCallback : public vtkCommand

function of pcl/visualization/pcl_visualizer.h. Then everything compiled fine. I dont need the FPSCallback so it's a perfect solution for me to run my code with \clr support.

Thanks drescherjm for your help!!
