Ruby (MRI) on Linux/OS X

You need MRI 1.9.3 or newer. OS X and Linux users can install this easily with RVM.

Now you need to install dependencies. cd to this directory (bool/ruby) and run:

gem install bundler && bundle

This should install the gems listed in bool.gemspec. If you have already managed to build the C code you should be fine to proceed and build the C extension. Just run

bundle exec rake

Ruby (MRI) on Windows

To build windows gems we need to precompile the C extension using MinGW. For OS X the top level Makefile should download MinGW, so all you need to do is to cd to the root directory and run:

make winruby

That should create a .so file under lib.

JRuby

You need JRuby 1.7.2 or newer. OS X and Linux users can install this easily with RVM.

If you have already managed to build the Java code you should be fine. You also need jruby on your PATH. RVM users can do this like so:

ln -s ~/.rvm/rubies/jruby-1.7.2/bin/jruby ~/bin/jruby
export PATH=$PATH:~/bin

Now just run

rake
