OpenCV将无法编译由于未解决的外部 - LNK2019 [英] OpenCV won't compile due to unresolved externals -- LNK2019

问题描述

我是OpenCV的全新产品，并一直试图在Visual Studios 2010 Ultimate中设置它。我已经完全遵循文档，并链接文件，因为它说。下面是我使用的额外库：

I am brand new to OpenCV and have been trying to set it up in Visual Studios 2010 Ultimate. I have followed the documentation exactly, and linked the files as it said. Here are the additional libraries that I am using:

opencv_core231d.lib
opencv_imgproc231d.lib
opencv_highgui231d.lib
opencv_ml231d.lib
opencv_video231d.lib
opencv_features2d231d.lib
opencv_calib3d231d.lib
opencv_objdetect231d.lib
opencv_contrib231d.lib
opencv_legacy231d.lib
opencv_flann231d.lib

但是，当我尝试调试&编译给我的示例代码，我得到以下错误。 （我读的地方，你必须编译并以发布项目才能正常工作吗？这是真的呢？）

And all of their Release counterparts. However, when I try to debug & compile the sample code given to me, I get the following errors. (I read somewhere that you have to compile and publish the project in order for it to work properly? Is that true as well?)

我浏览了所有目录，确认图书馆，事实上，存在于我的OpenCV文件，我的下载没有损坏或任何东西。任何帮助将不胜感激。

I went through all my directories and made sure that the libraries, did in fact, exist in my OpenCV files, and my download didn't corrupt or anything. Any help would be appreciated!

推荐答案

shambool在另一个线程只是指出你应该阅读此。

shambool in another thread just pointed that you should maybe read this.
