mac安装clion、opencv及简单测试

1. 安装clion

  在clion官网下载的安装包。本来在知乎上有妹子说这个软件学生免费，结果找了半天也没找到那个链接。在网上找了几个注册码也没成功，所以。。我的暴脾气。。就直接上淘宝买了一个，几块钱，剩下了时间成本，挺好的。哈哈哈～吧这个注册码贴出来，大家分享吧。clion的版本是mac版本的2017.2。注册码如下：

好长好长啊～哈哈哈～希望能够帮助到广大网友。

2. 安装opencv

  在bash中使用如下命令安装opencv。

brew install homebrew/science/opencv

同时，opencv和opencv2是可以同时存在的，可以使用如下命令安装opencv3。

brew install homebrew/science/opencv3

  在使用brew命令安装时，遇到了“-bash: brew: command not found“。原因是没有安装Homebrew。使用如下命令进行解决：

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"[/code] 
3. clion+opencv简单测试
  修改clion项目中的CMakeLists.txt，添加三行信息，修改后的样子如下所示：

cmake_minimum_required(VERSION 3.7)
project(untitled) #将untitled改为自己的工程名
find_package(OpenCV)
#或者find_package(OpenCV3)
include_directories( ${OpenCV_INCLUDE_DIRS} )
set(CMAKE_CXX_STANDARD 11)
set(SOURCE_FILES main.cpp)
add_executable(untitled ${SOURCE_FILES})
target_link_libraries( untitled ${OpenCV_LIBS} )


运行测试用例：

#include <iostream>
#include <opencv2/opencv.hpp>

using namespace std;
using namespace cv;
int main() {
Mat srcImage = imread("show.png");
imshow("[img]", srcImage);
waitKey(0);
return 0;
}
