在 Eclipse 中使用 opencv 2.4.10 编译代码

Compiling the code with opencv 2.4.10 in Eclipse

本文关键字：编译 代码 opencv Eclipse      更新时间：2023-10-16

编译下面的代码后，我发现错误如下所述。

#include <cv.h>
#include <highgui.h>
using namespace cv;
int main( int argc, char** argv )
{
  Mat image;
  image = imread( argv[1], 1 );
  if( argc != 2 || !image.data )
    {
      printf( "No image data n" );
      return -1;
    }
  namedWindow( "Display Image", CV_WINDOW_AUTOSIZE );
  imshow( "Display Image", image );
  waitKey(0);
  return 0;
}

生成项目时出错：

你不能将预构建的MSVC库（-LC：\opencv\build\x64\vc10\bin）与Mingw一起使用，它是一个不同的编译器。 获取 cmake，并使用它重建 OpenCV 库。（对不起，亲爱的，你没有其他办法。
