OpenCV xcode build Supporting tagline

在 osx 下构建 OpenCV 开发环境 OSX 10.8.2 XCode 4.6

1.获取源码

git clone https://github.com/Itseez/opencv.git

2.构建 mkdir build cd build cmake -G “Unix Makefiles” .. make -j8 sudo make install 如果构建成功,库和头文件会被放置在 /usr/local/ 目录下

3.新建工程

-新建 command line 工程
-在 Targets -> Build Phases 下添加库文件 libopencv_core_2.4.9.dylib libopencv_highgui_2.4.9.dylib libopencv_imgproc_2.4.9.dylib
-在 Build Settings下设置 Header Search Paths 并且设为 recusive
-用下面这段代码替换 main.cpp
		// Example showing how to read and write images
		#include <opencv2/opencv.hpp>
		#include <opencv2/highgui/highgui.hpp>
		#include <opencv/cvaux.hpp>
		int main(int argc, char** argv)
		{
		    IplImage * pInpImg = 0;

		    // Load an image from file - change this based on your image name
		    pInpImg = cvLoadImage("logo.jpg", CV_LOAD_IMAGE_UNCHANGED);
		    if(!pInpImg)
		    {
		        fprintf(stderr, "failed to load input image\n");
		        return -1;
		    }

		    // Write the image to a file with a different name,
		    // using a different image format -- .png instead of .jpg
		    if( !cvSaveImage("logo_copy.png", pInpImg) )
		    {
		        fprintf(stderr, "failed to write image file\n");
		    }

		    // Remember to free image memory after using it!
		    cvReleaseImage(&pInpImg);

		    return 0;
		}

4.编译错误

‘cvaux.h’ file not found with <angled> include; use "quotes" instead.   解决:
  
#include <cvaux.h>   替换成
#include "cvaux.h"
