Defined in:
lib/shoe/tasks/compile.rb

Overview

Defines `rake compile` to build your C extensions.

Uses {Gem::Ext::ExtConfBuilder}[http://rubygems.rubyforge.org/rubygems-update/Gem/Ext/ExtConfBuilder.html], so extensions are compiled locally just as they will be with `gem install`. Your users will thank you.

To enable and configure, add extensions[http://docs.rubygems.org/read/chapter/20#extensions] to your gemspec.
