1. app store下载xcode

2. OpenCV 官网下载OpenCV for linux/mac

3.安装homebrew

4.命令行使用brew install cmake 安装cmake

5.cd 到opencv解压后的文件夹，在命令行依次执行以下命令：

mkdir build

cd build

cmake -G

"Unix Makefiles"

..

make

sudo make install

至此opencv安装完毕

 

进入xcode新建命令行mac ox程序，使用c++语言

1.在项目build setting视窗中搜索 search path 修改以下项目

Always search User paths : true

Framework search path: /usr/local/lib

Header Search Paths ：/usr/local/include

Library Search Paths ： /usr/local/lib

2.build setting视窗中搜索 other linker flags

输入 

-lopencv_calib3d -lopencv_core -lopencv_features2d -lopencv_flann -lopencv_highgui -lopencv_imgcodecs -lopencv_imgproc -lopencv_ml -lopencv_objdetect -lopencv_photo -lopencv_shape -lopencv_stitching -lopencv_superres -lopencv_ts -lopencv_video -lopencv_videoio -lopencv_videostab

3.在Xcode偏好设置中Location->advanced，把 

Unique 改为 

Legacy.

4.在项目中新建一个文件夹，选"Add files to ..."，按 command+shift+g 输入路径 /usr/local/lib，把所有lib文件加入

5.完成！可以用以下代码测试，测试的图片路径自己修改：

#include 
      
       #include 
       
        #include 
        
         #include 
         
          #include 
          
           using namespace cv;using namespace std;int main( int argc, char** argv ){    string imageName("/Users/isware/Documents/MATLAB/Walrus_001.jpg"); // by default    if( argc > 1)    {        imageName = argv[1];    }    Mat image;    image = imread(imageName.c_str(), IMREAD_COLOR); // Read the file    if( image.empty() )                      // Check for invalid input    {        cout <<  "Could not open or find the image" << std::endl ;        return -1;    }    namedWindow( "Display window", WINDOW_AUTOSIZE ); // Create a window for display.    imshow( "Display window", image );                // Show our image inside it.    waitKey(0); // Wait for a keystroke in the window        return 0;    }
