Right now people who publish native gems targeting the windows platform have a problem. Our problem is supporting ruby 1.8 and 1.9 at the same time. Right now, we can’t build one gem targeting 1.8 and one gem targeting 1.9, and have rubygems differentiate the two. I have a solution: fat binary gems. We can build a gem that contains dynamic libraries that target ruby 1.8 and ruby 1.9 on windows, with no changes to rubygems whatsoever. I’ve put together a proof of concept that I want to share. I will walk through the steps for building a fat binary gem with the tools we have today. The steps I am going to present are not necessarily the best steps, they are just the steps I took to get this idea working.
