Mac10.11 + Qt5.7 + OpenCV2.4.13

本文主要是介绍Mac10.11 + Qt5.7 + OpenCV2.4.13，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

准备工作

1. QT官网下载安装Qt5.7.
2. Homebrew 官网，安装homebrew.
3. iTerm 官网下载安装iTerm2.
4. 启动 iTerm
   
$ brew update
$ brew info opencv
$ brew tap homebrew/science
$ brew install opencv --with-qt5 --with-ffmpeg --with-opengl --with-opencl


Qt 测试项目helloCV

helloCV.pro 末尾添加以下代码：

INCLUDEPATH += /usr/local/include
INCLUDEPATH += /usr/local/include/opencv
INCLUDEPATH += /usr/local/include/opencv2LIBS += -L/usr/local/lib \-lopencv_core \-lopencv_highgui \-lopencv_imgproc \

main.cpp 代码如下：

//#include "mainwindow.h"
//#include <QApplication>
//int main(int argc, char *argv[])
//{
//    QApplication a(argc, argv);
//    MainWindow w;
//    w.show();
//    return a.exec();
//}#include <iostream>
#include <string>
#include <vector>
using namespace std;#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <opencv2/imgproc/imgproc.hpp>
using namespace cv;int main(int argc, char *argv[])
{Mat src = imread("/Users/tianzhaixing/Pictures/jurassic_world.jpg");if(src.empty()){cerr << "Please check the path of input image!" << endl;return -1;}const string winname = "src";namedWindow(winname, WINDOW_AUTOSIZE);imshow(winname, src);waitKey(0);destroyWindow(winname);return 0;
}

问题

dyld: Symbol not found: __cg_jpeg_resync_to_restartReferenced from: /System/Library/Frameworks/ImageIO.framework/Versions/A/ImageIOExpected in: /usr/local/lib/libjpeg.8.dylibin /System/Library/Frameworks/ImageIO.framework/Versions/A/ImageIO
程序异常结束。
