Hi, Recently Gardens Point [Ruby.NET](http://Ruby.NET) Compiler was released. It’s available here: [http://plas.fit.qut.edu.au/Ruby.NET/](http://plas.fit.qut.edu.au/Ruby.NET/) This post is a walkthrough on how to compile it on Mono. First, you need to get Mono from SVN trunk. The latest release is 1.1.15 but it won’t do. (Missing property in System.IO.StreamReader.) Get SVN revision later than 60046. Next, you need to patch Mono C# compiler. GP [Ruby.NET](http://Ruby.NET) Compiler is beaten by Mono bug #77963, which causes deriving class from generic type whose generic argument is its nested class to fail. Unfortunately this is the case for Ruby.Dictionary class which derives from System.Collections.Generic.Dictionary\. This is obviously Mono’s fault, but it would be great if [Ruby.NET](http://Ruby.NET) team can move Key class out of Dictionary class to avoid this. So get the workaround patch by Atsushi Emoto from Mono bugzilla. Patch is a bit old, but you should have no problem finding where it is patching (it’s one-liner): [http://bugzilla.ximian.com/show\_bug.cgi?id=77963](http://bugzilla.ximian.com/show_bug.cgi?id=77963) And build Mono. It will take some time. As [Ruby.NET](http://Ruby.NET) uses MSBuild as its build system which is not yet supported in Mono, I prepared a simple Makefile. It would be nice if [Ruby.NET](http://Ruby.NET) team can include this in the next release. CSC=gmcs all: …/Bin/QUT.ShiftReduceParser.dll …/Bin/QUT.PERWAPI.dll …/Bin/QUT.RubyRuntime.dll …/Bin/RubyCompiler.exe …/Bin/QUT.ShiftReduceParser.dll: $(CSC) -t:library -out:…/Bin/QUT.ShiftReduceParser.dll -recurse:GPPG/ShiftReduceParser/\*.cs …/Bin/QUT.PERWAPI.dll: $(CSC) -t:library -out:…/Bin/QUT.PERWAPI.dll -recurse:PERWAPI/\*.cs …/Bin/QUT.RubyRuntime.dll: $(CSC) -t:library -r:…/Bin/QUT.ShiftReduceParser.dll -r:…/Bin/QUT.PERWAPI.dll -out:…/Bin/QUT.RubyRuntime.dll -recurse:RubyRuntime/\*.cs …/Bin/RubyCompiler.exe: $(CSC) -t:exe -r:…/Bin/QUT.PERWAPI.dll -r:…/Bin/QUT.RubyRuntime.dll -out:…/Bin/RubyCompiler.exe -recurse:RubyCompiler/\*.cs After that, [Ruby.NET](http://Ruby.NET)’s runtime library makes use of some API not yet implemented in Mono. Namely, they correspond to following Ruby methods: File.readable? File.readable\_real? File.writable? File.writable\_real? File.executable? File.executable\_real? File.owned? File.expand\_path, Dir.glob, IO.reopen. You can find this out by performing compile-delete cycle, which feels like a big waste of time, so I did it for you. Get it here: [http://sparcs.kaist.ac.kr/~tinuviel/download/patch-ruby.net](http://sparcs.kaist.ac.kr/~tinuviel/download/patch-ruby.net) Now, 1. Unpack Ruby.NET.beta0.5.src.zip (Be sure to get source distribution!) 2. Apply [patch-ruby.net](http://patch-ruby.net) 3. cd to [ruby.net at Directnic](http://Ruby.NET/Src) 4. Type make (Be sure that gmcs points to patched gmcs, edit Makefile if necessary) 5. ? 6. Profit! Thanks to #mono people on GIMPNet for help. ---
