OpenCV - Why this build error?

I have typed the following program from Learning OpenCV book:

#include "highgui.h"

int main(int argc, char *argv[])
{
  IplImage *img = cvLoadImage(argv[1]);
  cvNamedWindow("Example1", CV_WINDOW_AUTOSIZE);
  cvShowImage("Exam开发者_StackOverflowple1", img);
  cvWaitKey(0);
  cvReleaseImage(&img);
  cvDestroyWindow("Example1");
}

When I try to build it using Eclipse CDT, I get the following (Any ideas?):

Thanks.


You are possibly using a newer compiler than the OpenCV designers, so it reports a violation of the rules for templates. It also says that if you use -fpermissive, it will be less strict and do like the older compilers used to.

A quick googling also shows that there is now also an OpenCV 2.1. Perhaps that one works better?
