Image Science on Leopard

Updated: Monday 18th February 2008. Correction to makefile again! Apparently the previous change didn’t take =) Thanks to Peter Dunord for pointing this out.

Updated: Wednesday 21st November 2007. Corrections made to Makefile.osx naming and rubyinline install added to list.

Here is a quick guide to getting image_science working on your new leopard install. Full Credit to Michael Steinfeld for his directions on the ruby forum.

1. Install and update ruby_inline

1.1 Install

sudo gem install RubyInline

1.2 Update

• trac.macosforge.org Reference

cd /Library/Ruby/Gems/1.8/gems/RubyInline-3.6.4/lib
mate inline.rb

replace

flags = @flags.join(' ')

with

flags = @flags.join(' ') + ' -lruby'
cd 
rm -rdf ./ruby_inline

2. Ensure that xCode was installed with 10.3.9 support

2.1 Install from the leopard disk.

Links below show screenshots for installing 10.3.9 support

• Select optional Installs
• Run the xcode packge
• Select customize before installing
• Select 10.3.9 support

2.2 Check if you have it installed

$ ls /Developer/SDKs/

MacOSX10.3.9.sdk 
MacOSX10.4u.sdk
MacOSX10.5.sdk

4. Edit Makefile.osx LIBRARIES

mate ~/Downloads/FreeImage/Makefile.osx

replace lines

LIBRARIES_PPC = -Wl,-syslibroot /Developer/SDKs/MacOSX10.3.9.sdk
LIBRARIES_I386 = -Wl,-syslibroot /Developer/SDKs/MacOSX10.4u.sdk

with

LIBRARIES_PPC = -Wl,-syslibroot /Developer/SDKs/MacOSX10.3.9.sdk/usr/lib
LIBRARIES_I386 = -Wl,-syslibroot /Developer/SDKs/MacOSX10.4u.sdk/usr/lib

5. Install Free Image (ignore ppc symbol errors)

cd FreeImage
make
sudo make install

6. Install Image Science

sudo gem install image_science

7. Test

irb
>> require 'image_science'
>> true
