I am trying to implement opencv face detection using C++/CLI wrapper and accessing it from C#. But i got following error.
Can anybody help me,please help!.

error LNK2005: "struct CvSeq * pFaceRectSeq" (?pFaceRectSeq@@3PAUCvSeq@@A) already defined in FaceDetcCliWrapper.obj
error LNK2005: "struct _IplImage * pInpImg" (?pInpImg@@3PAU_IplImage@@A) already defined in FaceDetcCliWrapper.obj
error LNK2005: "struct CvHaarClassifierCascade * pCascade" (?pCascade@@3PAUCvHaarClassifierCascade@@A) already defined in FaceDetcCliWrapper.obj
error LNK2005: "struct CvMemStorage * pStorage" (?pStorage@@3PAUCvMemStorage@@A) already defined in FaceDetcCliWrapper.obj

我可以将其作为win32控制台应用程序运行在Visual Studio 10中。

I can able to run it as a win32 console application in Visual studio 10.

推荐答案

您的标题具有误导性：首先是链接器错误。 :-（



你已经声明了一些结构并将它们多次包含在内。为了解决这个问题，你应该在每个头文件的顶部写这个语句，这个类抛出这样的错误



#pragma一次

Your header is misleading: at first it are linker errors. :-(

You have declared some structs and included them multiple time. To solve this problem you should write this statement at the top in every header file which class throws such an error

#pragma once
