not before, but right now, i'm following the page "How to create a Ruby
extension in C in under 5 minutes"
<http://www.rubyinside.com/how-to-create-a-ruby-extension-in-c-in-under-
5-minutes-100.html>

i've allready done the "MyTest" example and want to adapt this strategy
to the jukebox given in "Extending Ruby" of "The Pragmatic Programmer's
Guide" <http://www.rubycentral.com/book/ext_ruby.html>.

here i've done the "cdjukebox.bundle" using mkmf however when wanting to
test by ruby i get :
dyld: NSLinkModule() error
dyld: Symbol not found: _CDPlayerSeek
  Referenced from: ./Jukebox/cdjukebox.bundle
  Expected in: flat namespace

the *.h and *.c are cut'n paste from pickaxe and my ruby test being :

require 'Jukebox/cdjukebox'
p = CDPlayer.new(1)
puts "Unit is #{p.unit}"
p.seek(3, 16) {|x| puts "#{x}% done" }
puts "Avg. time was #{p.seekTime} seconds"


also as it's done in pickaxe...

i wonder also how to translate my ObjC class into a C one, i've heard
they are tools for that ? (i've found the reverse C -> ObjC)
