Question

我在尝试使用64位Windows 8机器上的visual studio ultimate 2010设置opencv 2.4.6时出现问题。我知道要添加include和dll引用，但是当我执行代码时，我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：

我确实尝试在其他依赖项中添加.lib文件，但vs2010表示它没有检测到它们，因为我确实看到了另一篇文章，就像我的一样。 include目录包括通用“include”文件夹以及opencv和opencv2文件夹。然后我将build \ x64 \ vc10 \ lib，bin和staticlib添加到其他lib目录中。 opencv也被提取到c：\驱动器，所以那里不应该有任何问题。我提前感谢大家的帮助！

Answer 1

只需替换：

opencv_highgui243.lib

在：

opencv_highgui243d.lib

Answer 2

可能您已经包含了发布库而不是调试版本。

由于您已内置debug模式，因此库也应为debug版本，如：

opencv_highgui243d.lib

而不是

opencv_highgui243.lib

opencv vs 2010依赖项问题
