【问题描述】：

我在尝试在 64 位 Windows 8 机器上使用 Visual Studio Ultimate 2010 设置 opencv 2.4.6 时遇到问题。我知道要添加包含和 dll 引用，但是当我执行代码时，它会显示这个巨大的外部链接错误：

代码：

#include "opencv2/highgui/highgui.hpp"
#include <iostream>

using namespace cv;
using namespace std;

int main( int argc, const char** argv )

   Mat img = imread("mypic.JPG", CV_LOAD_IMAGE_UNCHANGED); //read the image data in the            file "MyPic.JPG" and store it in 'img'

  if (img.empty()) //check whether the image is loaded or not
  
      cout << "Error : Image cannot be loaded..!!" << endl;
      //system("pause"); //wait for a key press
      return -1;
  

  namedWindow("MyWindow", CV_WINDOW_AUTOSIZE); //create a window with the name "MyWindow"
  imshow("MyWindow", img); //display the image which is stored in the 'img' in the "MyWindow" window

  waitKey(0); //wait infinite time for a keypress

  destroyWindow("MyWindow"); //destroy the window with the name, "MyWindow"

  return 0;

错误是：

我确实尝试在附加依赖项中添加 .lib 文件，但是 vs2010 说它没有检测到它们，因为我确实看到了另一个与我的问题一样的帖子。 include 目录包括通用的“include”文件夹以及 opencv 和 opencv2 文件夹。然后我将 build\x64\vc10\lib、bin 和 staticlib 添加到附加的 lib 目录中。 opencv 也被提取到 c:\ 驱动器，所以那里应该没有任何问题。我提前感谢大家的帮助！

【参考方案1】：

只需替换：

opencv_highgui243.lib

开：

opencv_highgui243d.lib

【讨论】：

OP 正在使用 OpenCV 2.4.6。

好的，我尝试将所有调试 .lib 移动到一个单独的文件夹中，然后将其他依赖项设置到调试文件夹。我仍然遇到同样的错误。我仍然会尝试在 vs 中四处寻找，看看我是否遗漏了任何东西。我还应该注意“链接器”>>“输入”区域中的其他依赖项中的任何内容吗？再次感谢

哦，没关系，我发现库的目录也有问题，但你确实帮助了我很多调试与发布库。谢谢:-)

【参考方案2】：

您可能包含了发布库而不是调试版本。

因为你已经构建了debug模式，所以库也应该是debug版本，比如：

opencv_highgui243d.lib

而不是

opencv_highgui243.lib
