由于未解析的外部因素，OpenCV将无法编译 - LNK2019

标签： c++ visual-studio-2010 opencv unresolved-external lnk2019

我是OpenCV的新手，并一直试图在Visual Studios 2010 Ultimate中进行设置。我完全按照文档，并按照它说的链接文件。以下是我正在使用的其他库：

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

以及他们所有的Release版本。但是，当我尝试调试＆amp;编译给我的示例代码，我得到以下错误。 （我在某处读到你必须编译和发布项目以使其正常工作？这也是正确的吗？）

我浏览了所有目录并确保实际上存在于我的OpenCV文件中的库，并且我的下载没有损坏或任何其他内容。任何帮助将不胜感激！

答案 0 :(得分：7)

我遇到了同样的问题，发现我的目标是32位平台。答案是将我的项目更改为目标x64。说明位于：http://msdn.microsoft.com/en-us/library/vstudio/ms185328.aspx。

我还发现chaiy上面列出的参考文献非常有用。这是：http://docs.opencv.org/trunk/doc/tutorials/introduction/windows_visual_studio_Opencv/windows_visual_studio_Opencv.html#windows-visual-studio-how-to

答案 1 :(得分：4)

<{3}}中的shambool只是指出你应该阅读another thread。
