使用this tutorial，我试图合并使用opencv_createsamples创建的不同 vector ，以便进行一些haartraining。
我正在使用VS 2010命令行界面编译mergevec.cpp:
cl /EHsc mergevec.cpp
但是我收到10个无法解决的外部错误，在这里:
/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？
我一直在努力使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都从
"cv.h"更改为"opencv.h"，因为这是当前头文件的名称。我正在尝试在具有以下结构的文件夹中编译
mergevec.cpp: 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
文件夹
opencv2具有目录:core, highgui, flann, contrib等，等等。编辑
根据您的评论，我更改了命令以包括库:
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
但是它仍然显示相同的10个 Unresolved external 。无奈之下，我什至尝试包含每个库文件，但没有区别。
最佳答案
Visual Studio似乎找不到OpenCV库，似乎缺少了一个pkg-config问题。检查此内容，因为我不确定它在Windows上如何工作。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(无论是否为WM)下进行编译。检查此post以获取更多信息。
