Compiling Libical for arm64 and x86_64 for iOS

It took me a while to compile LibiCal for the arm64 architecture and x86_64 for iOS (device and simulator). Thought it might be useful to others. Here are the steps that I followed to compile LibiCal-1.0. I took the code from the link below

Compilation libical

and changed the bit for Xcode 5.1

1) download LibiCal from the site below

http://sourceforge.net/projects/freeassociation/

Disconnect and enter the libCal-1.0 folder. Then run

./ self-loading

(you must download the make tools from http://www.jattcode.com/installing-autoconf-automake-libtool-on-mac-osx-mountain-lion/ )

Use below script

#!/bin/sh

# SEE: http://www.smallsharptools.com/downloads/libical/

PATH="`xcode-select -print-path`/usr/bin:/usr/bin:/bin"

# set the prefix
PREFIX=${HOME}/Library/libical

# Select the desired iPhone SDK
export SDKVER="7.1"
export DEVROOT=`xcode-select --print-path`
export  SDKROOT=$DEVROOT/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS${SDKVER}.sdk
export IOSROOT=$DEVROOT/Platforms/iPhoneOS.platform
