Hi All, I’m following Aslak’s instructions here to get IronRuby running on Mono/OSX. [http://wiki.github.com/aslakhellesoy/cucumber/ironruby-and-mono](http://wiki.github.com/aslakhellesoy/cucumber/ironruby-and-mono) I’m getting a failure when I do the “rake compile mono=1” that it can’t find the pathname2 gem. Looking back on the list, I saw that was resolved by installing the pathname2, which I tried, and I also tried the “gem install -y pathname2” trick I saw on the list. What that got me was what is below. I did some more research and couldn’t find what was going on, so I thought I’d ask the list before I got too much further. Any ideas? ## cory-foys-macbook-pro:ironruby foyc$ rake -v compile mono=1 --trace(in /Users/foyc/Workspace/ironruby) /Users/foyc/Workspace/ironruby/Merlin/Main/Languages/Ruby/Scripts/irtests.rb:92: warning: don’t put space before argument parentheses \*\* Invoke compile (first\_time) \*\* Invoke happy (first\_time) \*\* Execute happy \*\* Invoke clean\_build (first\_time) \*\* Invoke happy \*\* Execute clean\_build \*\* Invoke compile:dlr (first\_time) \*\* Invoke compile:extension\_attributes (first\_time) \*\* Invoke clean\_build \*\* Execute compile:extension\_attributes ## dlr\_extension rake aborted! cannot resolve path System.dll /Users/foyc/Workspace/ironruby/Merlin/Main/Languages/Ruby/context.rb:96:in `resolve_framework_path' /Users/foyc/Workspace/ironruby/Merlin/Main/Languages/Ruby/context.rb:95:in `each’ /Users/foyc/Workspace/ironruby/Merlin/Main/Languages/Ruby/context.rb:95:in `resolve_framework_path' /Users/foyc/Workspace/ironruby/Merlin/Main/Languages/Ruby/context.rb:136:in `resolve\_framework\_path’ /Users/foyc/Workspace/ironruby/Merlin/Main/Languages/Ruby/context.rb:339:in `resolve_framework_path' /Users/foyc/Workspace/ironruby/Merlin/Main/Languages/Ruby/context.rb:351:in `references’ /Users/foyc/Workspace/ironruby/Merlin/Main/Languages/Ruby/context.rb:349:in `each' /Users/foyc/Workspace/ironruby/Merlin/Main/Languages/Ruby/context.rb:349:in `references’ /Users/foyc/Workspace/ironruby/Merlin/Main/Languages/Ruby/context.rb:279:in `compile' /Users/foyc/Workspace/ironruby/Merlin/Main/Languages/Ruby/context.rb:277:in `chdir’ /Users/foyc/Workspace/ironruby/Merlin/Main/Languages/Ruby/context.rb:277:in `compile' /Users/foyc/Workspace/ironruby/Merlin/Main/Languages/Ruby/rake/compile.rake:24 /usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:636:in `call’ /usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:636:in `execute' /usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:631:in `each’ /usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:631:in `execute' /usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:597:in `invoke\_with\_call\_chain’ /usr/local/lib/ruby/1.8/monitor.rb:238:in `synchronize' /usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:590:in `invoke\_with\_call\_chain’ /usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:607:in `invoke_prerequisites' /usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:604:in `each’ /usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:604:in `invoke_prerequisites' /usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:596:in `invoke\_with\_call\_chain’ /usr/local/lib/ruby/1.8/monitor.rb:238:in `synchronize' /usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:590:in `invoke\_with\_call\_chain’ /usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:607:in `invoke_prerequisites' /usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:604:in `each’ /usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:604:in `invoke_prerequisites' /usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:596:in `invoke\_with\_call\_chain’ /usr/local/lib/ruby/1.8/monitor.rb:238:in `synchronize' /usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:590:in `invoke\_with\_call\_chain’ /usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:583:in `invoke' /usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:2051:in `invoke\_task’ /usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:2029:in `top_level' /usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:2029:in `each’ /usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:2029:in `top_level' /usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:2068:in `standard\_exception\_handling’ /usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:2023:in `top_level' /usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:2001:in `run’ /usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:2068:in `standard_exception_handling' /usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:1998:in `run’ /usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/bin/rake:31 /usr/local/bin/rake:19:in `load’ /usr/local/bin/rake:19 cory-foys-macbook-pro:ironruby foyc$ mono --version Mono JIT compiler version 2.6.1 (tarball Thu Dec 17 10:19:23 MST 2009) Copyright (C) 2002-2008 Novell, Inc and Contributors.

It’s a pitty those instructions are around because they are really outdated you can get a mono built binary for RC2 here: [http://dl.dropbox.com/u/21717/ironruby-rc2.tar.bz2](http://dl.dropbox.com/u/21717/ironruby-rc2.tar.bz2) if you want to build on mono and get a few launcher scripts you can use my linux branch from git://github.com/casualjim/ironruby.git to compile: cd ironruby ./build ## The rake build requires ruby 1.8 Met vriendelijke groeten - Best regards - Salutations Ivan Porto C.

Hi Ivan, Ivan Porto C. wrote: > to compile: > cd ironruby > ./build > > The rake build requires ruby 1.8 I got the exact same Pathname2 error - I did a git clone from your repo and did a rake. Any thoughts? But the binary seems to be working fine, so that will be a good start. Thanks! Cory ---

don’t do rake try using the ./build script it sets an environment variable MERLIN\_ROOT ## you need ruby 1.8.x to build it and you need to install the pathname2 gem Met vriendelijke groeten - Best regards - Salutations Ivan Porto C. - Mob: +32.486.787.582 Web: [http://whiterabbitconsulting.eu](http://whiterabbitconsulting.eu) - [http://flanders.co.nz](http://flanders.co.nz) Twitter: [http://twitter.com/casualjim](http://twitter.com/casualjim) Author of IronRuby in Action ([IronRuby in Action - Ivan Porto Carrero and Adam Burmister | Manning](http://manning.com/carrero)) Microsoft IronRuby/C# MVP
