IOS linking error OpenCV 2.4.7

edit

Hi I am trying to link an IOS OpenCV 2.4.7 Face detection application in Xcode 5.1 and I am getting the following error:

ld: warning: ignoring file /Users/marcio/Downloads/opencv-2.4.7/ios/opencv2.framework/opencv2, missing required architecture x86_64 in file /Users/marcio/Downloads/opencv-2.4.7/ios/opencv2.framework/opencv2 (3 slices) Undefined symbols for architecture x86_64: "_OBJC_CLASS_$_CvVideoCamera", referenced from: objc-class-ref in ViewController.o ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

I have download openCv from the OpenCV site and followed the directions to compile and install the framework in Xcode. I have checked the ld command and it is trying to use the correct iPhone simulator files.

Below is the output of the ld command:
