c++ - OpenCV - 为什么这个构建错误？

Question

我从 Learning OpenCV 一书中输入了以下程序:

#include "highgui.h"

int main(int argc, char *argv[])
{
  IplImage *img = cvLoadImage(argv[1]);
  cvNamedWindow("Example1", CV_WINDOW_AUTOSIZE);
  cvShowImage("Example1", img);
  cvWaitKey(0);
  cvReleaseImage(&img);
  cvDestroyWindow("Example1");
}

当我尝试使用 Eclipse CDT 构建它时，我得到以下信息(有什么想法吗？):

您可能使用比 OpenCV 设计者更新的编译器，因此它报告违反模板规则。它还表示，如果您使用 -fpermissive，它将不那么严格，并且会像过去的旧编译器一样。

快速谷歌搜索还显示现在还有一个 OpenCV 2.1。也许那个效果更好？
