Gecode/r is a wrapper around <a href="http://www.gecode.org/">Gecode</a>, so you'll need to also install Gecode before installing Gecoder/r. I started out using the disk image for Mac OSX 10.4, but Gecode/r would produce the following error when I tried to require Gecode/r:</p> <div class="typocode"><pre><code class="typocode_default ">irb(main):002:0&gt; require 'gecoder' dyld: NSLinkModule() error dyld: Symbol not found: __ZNK6Gecode9Exception4whatEv Referenced from: /usr/local/lib/ruby/gems/1.8/gems/gecoder-0.3.0/lib/gecode.bundle Expected in: flat namespace</code></pre></div> <p>It turns out, I have to download Gecode source and compile it on my Mac. After that, all I had to do is: gem install gecoder.</p> Thu, 05 Jul 2007 21:57:00 -0500 urn:uuid:bf6984a8-e45a-4790-aed1-a022bf558640 Aaron Feng http://www.aaronfeng.com/articles/2007/07/05/gecode-r-under-mac-osx programming
