XCode: Apple Mach-O Linker Error with New iOS 6 while adding self created static library

Question

I am created static library files and added that in to My Project XCode while compile it's throughs Apple Mach-O Linker Error,

My Static libraries
1.libMathLibrary.a
2.libDineshLibrary.a

I have checked

Target->Build Phases ->Link Binary with Libraries my static library added
LIBRARY_SEARCH_PATHS = $(inherited) "$(SRCROOT)/staticlb/libMathLibrary" "$(SRCROOT)/staticlb/libDineshLibrary" add static library path.

How to I resolve this problem. Please share your ideas, I hope it will help me..Thank you.

libDineshLibrary static library link error Undefined symbols for architecture armv7s: "_OBJC_CLASS_$_libDineshLibrary", referenced from: objc-class-ref in ViewController.o — GR.
I found when i created static library in simulator mode it will support xcode with simulator compelling only when it compile in device it will through linker errors vise-versa in device also. — GR.
This is link I referred to create static library: icodeblog.com/2011/04/07/creating-static-libraries-for-ios — GR.

I found solution for my problem

After created your own static .a extension library files

1. **libdevice.a** (device mode compile static library file)
2. **libsimulator.a** (simulator mode compile static library file)

Please convert two compile mode static libraries to one common static .a extension library

in your terminal

lipo -create libdevice.a libsimulator.a -output libcommonlibrary.a

The new libcommonlibrary.a common static library file will support both simulator and device compilation.
