Universal C/C++ Static Library for iPhone simulator and device by GCC compiling

This shows how to create universal static library to use c/c++ code for iPhone applications. Here, my cpp code is MathFuncsLib.cpp and MathFuncsLib.h.

I created following script file and run it to get "libMathFuncsLib-fat.a".


#!/bin/bash
