I get an error (see below) when I run the example script in the readme after gem install libtcod(0.0.9) using Ruby 1.9.3

The error is coming from FFI. The version of FFI that came with this ruby (p545) is 1.0.9. When I upgrade to ffi-1.9.3 the error goes away.

I've not managed to get mouse support working. Waiting for any event will not respond to mouse events and explicitly calling mouse_get_status returns an empty struct (zeroed out by fffi I think). Has anyone else had simillar problems?

Ran the example script. Here's what I got.

I was rewriting some of the code when I came across a typo in the "console.rb". @height is assigned the value for width:

def initialize(w, h, root=false)
if root
@ptr = nil
else
@width = w
@height = w
@ptr = TCOD.console_new(w, h)
end

  ObjectSpace.define_finalizer(self, self.class.finalize(ptr))
end

Not sure if you're still actively developing, but if you are, then you might consider sub-classing Console and get the root_console as a separate class. It'll allow you to get rid of having that third parameter in the constructor while still being able to pass rootconsoles everywhere you pass regular consoles. It seems more rubyesque to do it that way.

Here's an example from my port:

module Rogue
  class RootConsole < Console
    def initialze(width, height)
      if width < 0
        fail ArgumentError, "width must be non-negative, was #{width}"
      elsif height < 0
        fail ArgumentError, "width must be non-negative, was #{width}"
      end

      @width = width
      @height = height
      @clear_cell = Console.clear_cell
      @out_of_bounds_cell = Console.out_of_bounds_cell
      @ptr = nil

      ObjectSpace.define_finalizer(self, self.class.finalize(@ptr))
    end

    def self.instance
      @instance ||= create_instance
    end

    def self.create_instance
      unless Rogue::System.initialized?
        error_message = "Rogue::System.initialize has not been called yet."
        fail error_message 
      end

      RootConsole.new(System.SCREEN_WIDTH, System.SCREEN_HEIGHT)
    end
    private_class_method :create_instance
  end
end

The example program libtcod-ruby-test works fine on my system. However, when I exit by pressing ESC, the program closes the main window and hangs. Standard CTRL+C kills the program.

I placed a puts at the end of the program and that executes.

I've tried recompiling libtcod from source against my system's SDL and I still get the same behaviour. Doing a backtrace in gdb shows it's hanging in pthread_join called from SDL_WaitThread() and (via some intermediate functions) SDL_Quit().

I'm running 64-bit Ubuntu 13.10 on an AMD system.
