- Homebrew is a god horse
The Linux system has a common problem, which is package dependencies. Fortunately, the two current mainstream distributions have their own solutions. Red hat has yum, and Ubuntu has apt-get.
Shenma, you use mac os, sorry that Mac os doesn't have similar stuff, after many toss and tears, I finally found third-party support: Homebrew, Homebrew referred to as brew, is a package management tool on Mac OSX, which can be used on Mac It can be said that Homebrew is the apt-get and yum artifact under mac.
- Homebrew installation
The installation of Homebrew is very simple, open the terminal and copy and paste the following commands, press Enter, and you are done (please use it with confidence, the original official installation method is carried)
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"- Homebrew use

end of reference
unable to access ‘https://github.com/Homebrew/brew/‘: Failed to connect to github.com
The above error occurs because Github is blocked. The solution is to modify the hosts file
MAC method: Fidner->Go to folder->/private/etc
After finding the hosts file, copy it to the desktop, then open it on the desktop, and add the following lines. If the following fails, you can find a new IP
192.30.253.118 http://gist.github.com
192.30.253.119 http://gist.github.com
192.30.253.113 github.com
After the modification is completed, replace the hosts under the /private/etc folder with the desktop hosts.
1. Install wget
Method: Enter the following command
brew install wget2. Install cmake
Method: Enter the following command
brew install cmake3. Install OpenCV
brew install opencvThe location where Opencv is installed is: /usr/local/Cellar/opencv
Next, we can configure OpenCV. First, create a new project in XCode. After creating a new project, add dependencies and header files.
Double-click the first box, and then click on the lower left corner. +, you can add the address
Then create a new folder under the project, and drag the files with the suffix .dylib under /usr/local/Cellar/opencv/3.4.1_4/lib into this folder.
PS: After I opened it, I found a lot. The Internet said that the number of files was 18, and then a great god said that the ones with arrows should not be ignored, so I only dragged the ones without arrows, but they exceeded 18. Maybe my version is relatively new. Then you're done, find and test the test code yourself.
