在 Visual Studios 2010 Express C++ 中导入 OpenCV2.3 库时出现未解决的外部符号错误
第一次在这里向 stackoverflow 发布问题.对不起,如果我破坏了格式!
first time posting a question here to stackoverflow. Sorry if I butcher the formatting!
我正在尝试遵循有关 openCV 的基本教程,即:http://aishack.in/tutorials/tracking-colored-objects-in-opencv/
I am attempting to follow a basic tutorial on openCV, namely this one: http://aishack.in/tutorials/tracking-colored-objects-in-opencv/
我在网上看了很多关于如何安装 openCV 的教程,包括:
I have looked at various tutorial online on how to install openCV, including:
为 Visual Studio 2010 设置 OpenCV-2.3和opencv.willowgarage.com/wiki/VisualC%2B%2B
Setup OpenCV-2.3 for Visual Studio 2010 and opencv.willowgarage.com/wiki/VisualC%2B%2B
运气不佳.
我现在运行的当前版本是 OpenCV 2.3.0.我目前使用 Microsoft Visual C++ Express 2010 在 Windows 7 上运行.
The current version I have running right now is OpenCV 2.3.0. I am currently running on Windows 7 with Microsoft Visual C++ Express 2010.
每当我尝试构建和运行我的代码时,我都会收到以下错误:
Whenever I try to build and run my code, I get the following errors:

我查看了其他论坛、其他堆栈溢出问题等,但没有太多帮助.在周末的大部分时间里,我一直试图让它发挥作用.任何帮助将不胜感激!
I've looked at other forums, other stack overflow questions, ect without much help. I have been trying to get this to work for the better part of a weekend. Any help would be much appreciated!
如果您明确设置了与所有必要库的链接,但仍然显示链接错误,则您可能混淆了 64/32 位库和应用程序.
If you DID explicitly set up linking with all the necessary libraries, but linking errors still show, you might be mixing up 64/32 bit libraries and application.
即如果您正在构建 32 位应用程序,请确保所有库都包含指向 32 位版本的库.
I.e. make sure that all library includes point to 32 bit version of libraries if you are building 32 bit application.
