使用本教程，我正在尝试合并使用创建的不同向量，opencv_createsamples以便我可以进行一些训练。

我正在使用 VS 2010 命令行界面编译 mergevec.cpp：

cl /EHsc mergevec.cpp

但是我在这里收到了 10 个未解决的外部错误：

/out:mergevec.exe
mergevec.obj

mergevec.obj : error LNK2019: unresolved external symbol _cvFree_ referenced in function "void __cdecl icvAppendVec(struct CvVecFile &,struct CvVecFile &,int *,int,int)" (?icvAppendVec@@YAXAAUCvVecFile@@0PAHHH@Z)

mergevec.exe : fatal error LNK1120: 10 unresolved externals

我该如何解决这些问题？我需要获取一些 .dll 吗？我一直在努力让 mergevec 在不同的机器上工作 2 天！这是旧的问题吗？

顺便说一句，我将代码中的所有引用从 更改"cv.h"为"opencv.h"，因为那是当前头文件的名称。

我正在尝试mergevec.cpp在具有以下结构的文件夹中编译：

  opencv/
  opencv2/

CMakeLists.txt
createsamples.cpp
cvboost.cpp
cvclassifier.h
cvcommon.cpp
cvhaarclassifier.cpp
cvhaartraining.cpp
cvhaartraining.h
cvsamples.cpp
cxcore.h
cxmisc.h
haartraining.cpp
mergevec.cpp
opencv.hpp
performance.cpp
_cvcommon.h
_cvhaartraining.h

该文件夹opencv2有目录：core, highgui, flann, contrib等等等。

编辑

根据您的评论，我更改了命令以包含库：

cl /EHsc mergevec.cpp 
C:\opencv\build\x64\vc10\lib\opencv_core247d.lib 
C:\opencv\build\x64\vc10\lib\opencv_highgui247d.lib 
C:\opencv\build\x64\vc10\lib\opencv_flann247d.lib 
C:\opencv\build\x64\vc10\lib\opencv_imgproc247d.lib

但它仍然显示相同的 10 个未解决的外部。绝望中，我什至尝试包含每个库文件，但没有区别。

Visual Studio 似乎没有找到 OpenCV 库，这似乎是一个 pkg-config 缺失的问题。检查这一点，因为我不确定它如何在 Windows 上工作。您是否在项目属性中链接了 OpenCV 库？

否则，如果它仍然无法在 VS 上运行，我建议您在 Linux 下编译它（WM 与否）。查看此帖子以获取更多信息。
