在Mac OSX 10.10 上安装opencv

1. 按照正常的步骤，使用eclipse建立一个Mac C++工程，包含一个cpp文件。

#include <iostream>
#include <opencv2/opencv.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <opencv/cvaux.hpp>
#include <fstream>
using namespace std;

#define BYTE unsigned char

int main(int argc, const char * argv[])
{
    // insert code here...
#if 1
    //get the image from the directed path
           IplImage* img = cvLoadImage("/Users/kirchhoff/twd.png", 1);
           //NSLog(img);
           //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");
#endif
           //return
           return 0;
}

2. 右击工程名, 选择“Properties”，在属性配置页中选择，点击C/C++ Build, 在下拉选项中选择 Settings. 在右边的选项卡中选择 Tool Settings。
3. 在GCC C++ Compiler选项列表中选择Includes，在Include paths(-l)中添加安装好的opencv的头文件存放目录：/usr/local/Cellar/opencv/2.4.9/include
4. 在MacOS X C++Linker选项列表中选择Library，在Library search path (-L)中添加安装好的opencv Lib文件存放目录：/usr/local/Cellar/opencv/2.4.9/lib
5. 在MacOS X C++Linker选项列表中选择Library, 在Libraries(-l) 中依次点击“＋”号，添加需要使用的Lib文件(通常情况下，使用前三个)：
opencv_core opencv_imgproc opencv_highgui opencv_ml opencv_video opencv_features2d opencv_calib3d opencv_objdetect opencv_contrib opencv_legacy opencv_flann
6. 重新build all工程，大功告成～～＊^_^＊
