Hi, two things: - I’m sharing in case it’s useful to someone else: I pushed some rake tasks here [GitHub - thbar/ironruby-labs: Experimentations with IronRuby](http://github.com/thbar/ironruby-labs/tree/master) . I’m using it to download the DLR nightly to my Mac, patch ir.exe.config and launch mono ir.exe. I’ll add more things there as I go (including UI, experimentations etc). - is “mono Release/ir.exe -D somefile.rb” supposed to work with Mono 2.2 and the latest DLR build (10584) ? It seems that I’m facing the issue Ivan reported a while back: Macintosh:ironruby-labs thbar$ mono Release/ir.exe -D ui/ui.rb mscorlib:0:in `set_Fallback': Argument cannot be null. (System::ArgumentNullException) from mscorlib:0:in `.ctor’ from mscorlib:0:in `GetDecoder' from mscorlib:0:in `Initialize’ from mscorlib:0:in `.ctor' from mscorlib:0:in `.ctor’ cheers, – Thibaut ---

I have this bug fixed in my linux/mono branch. File a bug (if there isn’t one already) and I’ll submit my patch to it. On Mon, Feb 9, 2009 at 7:48 PM, Thibaut Barrère ---

When I build mono from svn then the compression stuff seems to be improperly linked. I have no idea what I should be doing to make that link properly that way I can just keep up with the trunk version on my laptop. ---

Alternatively,the mono-2-4 branch from svn should work as well, and will always be up to date.
