我试图编译一些OpenCv函数，并且从目录C:\ OpenCV2.2 \ modules \ haartraining中包含了cvhaartraining.h。

我把项目>'您的项目名称'属性...>配置属性>链接器>输入>

opencv库中的所有.lib文件:

"C:\OpenCV2.2\lib\opencv_highgui220d.lib" "C:\OpenCV2.2\lib\opencv_core220d.lib" "C:\OpenCV2.2\lib\opencv_ml220d.lib" "C:\OpenCV2.2\lib\opencv_video220d.lib" "C:\OpenCV2.2\lib\opencv_legacy220d.lib" "C:\OpenCV2.2\lib\opencv_imgproc220d.lib" "C:\OpenCV2.2\lib\opencv_objdetect220d.lib" "C:\OpenCV2.2\lib\opencv_ts220.lib" "C:\OpenCV2.2\lib\opencv_calib3d220d.lib" "C:\OpenCV2.2\lib\opencv_contrib220d.lib" "C:\OpenCV2.2\lib\opencv_features2d220d.lib"

最佳答案

您还有什么额外的lib文件？从谷歌搜索看来，它似乎已编译成一个名为cvhaartraining.lib的文件。
