OpenCV 2.4 build Failed error while creating iOS framework in Mac

edit

I have followed the following steps to install opencv on my mac. But I am getting a 'Build Failed' message.

What is the solution for this ?

Steps that I have followed:

1. Create a New Folder OpenCV in Desktop Working Directory.
2. In Terminal cd /Users/administrator/Desktop/OpenCV
3. In Terminal git clone https://github.com/Itseez/opencv.git

This results in the cutting edge OpenCV from GIT repository

1. Now install CMake software
2. In Terminal cd /
3. In Terminal sudo ln -s /Applications/Xcode.app/Contents/Developer Developer
4. In Terminal cd /Users/administrator/Desktop/OpenCV (open working directory)
5. In Terminal python opencv/ios/build_framework.py ios

Result of this is the build failed message.

The following build commands failed:
    Libtool /Users/administrator/Desktop/OpenCV/ios/build/iPhoneSimulator-i386/modules/world/UninstalledProducts/libopencv_world.a normal i386
(1 failure)
