# This is updated version from http://www.cloudgoessocial.net/2009/06/09/imagemagick-on-iphone-with-jpeg-png/ 

# Script to make static libraries (jpeg + png) and ImageMagick

# the libraries will be conbined into i386+arm.a static libraries

# to be used inside an XCODE project for iPhone development

# The directory structure has to be:

# ~/Desktop/cross_compile/i_m/ <- ImageMagick top directory

#   |-IMDelegataes/ <- Some delegates, in particular jpeg + png

# |-jpeg-6b/ <- Patched jpeg6b

# |-libpng-1.2.37 <- png lib - no need to patch it

# |-tiff-3.8.2 <- tiff lib - no need to patch it

#   |-... <- we don't care what's here! :)

# If you don't have this Directory structure you can either create it or try change around the script

#!/bin/bash

# Set this to the top directory of ImageMagick source:

IM_DIR=/Users/$USER/Desktop/cross_compile/i_m

JPEG_DIR=$IM_DIR/IMDelegates/jpeg-6b

PNG_DIR=$IM_DIR/IMDelegates/libpng-1.2.37

TIFF_DIR=$IM_DIR/IMDelegates/tiff-3.8.2

# Set this to where you want the libraries to be placed (if dir is not present it will be created):

LIB_DIR=$TARGET_LIB_DIR/im_libs

JPEG_LIB_DIR=$TARGET_LIB_DIR/libjpeg

PNG_LIB_DIR=$TARGET_LIB_DIR/libpng
