System Info: Ubuntu 11.10 (64 bits) with OpenCV 2.3 (installed today)
I'm trying to compile some very simple code in OpenCV 2.3 but I'm getting a weird error.
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
int main(){
cv::Mat image=cv::imread("img.jpg");
cv::namedWindow("My Image");
cv::imshow("My Image",image);
cv::waitKey(0);
return 1;
}
however, I'm getting these error messages...
