# Installation in iOS

## Required Packages

> - CMake 2.8.8 or higher
> - Xcode 4.2 or higher

### Getting the Cutting-edge OpenCV from Git Repository

Launch GIT client and clone OpenCV repository from here

In MacOS it can be done using the following command in Terminal:

    cd ~/<my_working _directory>
    git clone https://github.com/Itseez/opencv.git

## Building OpenCV from Source, using CMake and Command Line

1. Make symbolic link for Xcode to let OpenCV build scripts find the compiler, header files etc.

   >     cd /
   >     sudo ln -s /Applications/Xcode.app/Contents/Developer Developer

2. Build OpenCV framework:

   >     cd ~/<my_working_directory>
   >     python opencv/platforms/ios/build_framework.py ios

If everything’s fine, a few minutes later you will get ~/<my_working_directory>/ios/opencv2.framework. You can add this framework to your Xcode projects.
