Question

我想在Eclipse Neon for C ++中使用OpenCV。不幸的是，在构建项目时存在一些链接错误。

我按照this教程并通过了以下步骤：

安装Eclipse Neon for C / C ++（Windows 64位）http：//www.eclipse.org/downloads/packages/eclipse-ide-cc-developers/neon1a
在文件夹C：\ MinGW
在Windows C：\ opencv
在eclipse中创建一个新的空C ++项目
添加教程
添加没有出现任何错误的源文件Test.cpp

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

    using namespace cv;
    using namespace std;

    int main(int argc, char** argv)
    {
      Mat im = imread(argc == 2 ? argv[1] : "lenna.png", 1);
      if (im.empty())
      {
        cout << "Cannot open image!" << endl;
        return -1;
      }
      imshow("image", im);
      waitKey(0);
      return 0;
    }

构建项目

构建项目会返回以下错误：

哪里可以出错？

感谢您的帮助！
