opencv2.framework/opencv2(surf.o) duplicate symbols for architecture armv7

I am integrating opencv2.framework with my project. I did the following steps for completion.

  1. Added opencv2.framework to "Linked Frameworks and Libraries"
  2. Added libc++.dylib to "Linked Frameworks and Libraries"

  3. Added following code to AppName-Prefix.pch file

    #ifdef __cplusplus
    #import "opencv2/opencv.hpp"
    #endif

  4. Changed compiler default of Apple LLVM compiler 4.2 - Language -> C++ Language Dialect -> GNU++11 [-std=gnu++11] C++ Standard Library -> libc++ (LLVM C++ standard libray with C++ 11 support)

Still I am getting a link error which is saying

"opencv2.framework/opencv2(surf.o) ld: 21 duplicate symbols for architecture armv7"

Can anyone help me on this?

EDIT:

My XCode version is 4.6, IOS SDK is 6.1 and deployment target is 4.3 (I tested with 5.0 also, but not working in that target too)
