在本教程中，我尝试合并使用opencv_createsamples创建的不同向量，以便我可以进行一些haartraining。
我正在使用VS 2010命令行界面编译mergevec.cpp：
cl /EHsc mergevec.cpp
但是我在这里收到 10 个未解决的外部错误：
/out:mergevec.exe
mergevec.obj

mergevec.exe : fatal error LNK1120: 10 unresolved externals
如何解决这些问题？我需要获取一些 .dll 吗？2 天来，我一直在努力让 mergevec 在不同的机器上工作！问题是这是旧的吗？
顺便说一下，我将代码中的所有引用从 "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有目录：core, highgui, flann, contrib等。
编辑
根据您的评论，我更改了命令以包含库：
cl /EHsc mergevec.cpp
C:opencvbuildx64vc10libopencv_core247d.lib
C:opencvbuildx64vc10libopencv_highgui247d.lib
C:opencvbuildx64vc10libopencv_flann247d.lib
C:opencvbuildx64vc10libopencv_imgproc247d.lib
但它仍然显示相同的 10 个未解决的外部。在绝望中，我什至尝试包括每个库文件，但没有区别。
Visual Studio似乎找不到OpenCV库，这似乎是一个pkg-config缺失的问题。检查这一点，因为我不确定它在 Windows 上的工作方式。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（WM与否）下编译它。查看这篇文章以获取更多信息。
