Ironruby core - Oct 2009 - IronRuby, RubyZip and ZLib == error

Hello,

Just tried to use RubyZip with IronRuby (porting a rake task onto
irake) and I received the following error:

rake aborted!
wrong number of arguments (2 for 0)
c:/ironruby/lib/ironruby/gems/1.8/gems/rubyzip-0.9.1/lib/zip/zip.rb:1073:in

`commit''

Line of code is: @zlibDeflater = Zlib::Deflate.new(level, -Zlib::MAX_WBITS)

Method:
    def initialize(outputStream, level = Zlib::DEFAULT_COMPRESSION)
      super()
      @outputStream = outputStream
      @zlibDeflater = Zlib::Deflate.new(level, -Zlib::MAX_WBITS)
      @size = 0
      @crc = Zlib::crc32
    end

Any ideas what is causing the problem?

My IronRuby version is irb 0.9.5(05/04/13)

Thanks

Ben

Hi Benz,
	IronRuby has Standard zlib built-in. Can you try this?

require ''zlib''

z = Zlib::Deflate.new
dst = z.deflate(''foo'', Zlib::FINISH)

Hope this helps,
