I have built the OpenCV libraries using the cmake
build system as described here and have added the header, '.a' and '.dylib' files to my terminal c++ project. However when I run the code below (got it from http://iphone-cocoa-objectivec.blogspot.com/2009/01/using-opencv-for-mac-os-in-xcode.html), it gives me the errors below. Has anyone got any advice? Any help will be much appreciated.
#include <stdlib.h>
#include <stdio.h>
#include <math.h>
#include <cv.h>
#include <highgui.h>
int main()
{
//get the image from the directed path
IplImage* img = cvLoadImage("/Users/somedir/Programming/TestProj/fruits.jpg", 1);
//create a window to display the image
cvNamedWindow("picture", 1);
//show the image in the window
cvShowImage("picture", img);
//wait for the user to hit a key
cvWaitKey(0);
//delete the image and window
cvReleaseImage(&img);
cvDestroyWindow("picture");
//return
return 0;
}
