错误 LNK2019:未解析的外部符号 _ 打开 CV 程序 [英] error LNK2019: unresolved external symbol _ Open CV program
问题描述
我正在学习开放简历，同样我尝试了几个程序.我指的是这个链接.http://docs.opencv.org/modules/contrib/doc/facerec/tutorial/facerec_gender_classification.html
I am learning open CV and for the same i was trying few programs. I am referring to this link. http://docs.opencv.org/modules/contrib/doc/facerec/tutorial/facerec_gender_classification.html
我正在使用 Visual Studio 10 来运行它，我想我在某个地方搞砸了一些配置.我在更多程序中面临同样的问题(来自同一来源)，
I am using visual studio 10 to run the same, and i think somewhere i have messed up with some configuration. I am facing the same problem in couple of more programs (picked from same source) ,
我得到的错误如下:-
The error which i get is as follows:-
1>main.obj : error LNK2019: unresolved external symbol "int __cdecl cv::waitKey(int)" (?waitKey@cv@@YAHH@Z) 在函数 __catch$_main$0 中引用
1>main.obj : error LNK2019: unresolved external symbol "int __cdecl cv::waitKey(int)" (?waitKey@cv@@YAHH@Z) referenced in function __catch$_main$0

谢谢.
推荐答案
感谢@miki，我能够成功构建文件.我的问题的解决方案是:-
Thanks to @miki i was able to build the file successfully. The solution to my problem was:-
- 在属性->链接器->输入中添加适当的附加依赖项.
- 在 Windows 环境变量中添加库路径.
- 我没有使用@miki 所指出的和他引用的适当的附加依赖项好吧，你还必须在链接器中链接 opencv_coreXXX、opencv_highguiXXX、opencv_imgprocXXX 等......(如果在调试中，尾随为d")->输入---附加依赖项"
再次感谢
