Problem with openCV cvLoadImage(), cvSaveImage()

Many error occured when I use cvLoadImage(), cvSaveImage().

#include "ofApp.h"
#include <highgui.h>

//--------------------------------------------------------------
void ofApp::setup(){
    IplImage * result = cvLoadImage("a.bmp", 0);

}

ld: symbol(s) not found for architecture x86_64

I tried different option(i386), but result is same.

My system is OS X 10.11, Xcode 7.1, oF 0.9.0.
