I’ve just gotten the latest ironruby bits from github and cannot build. Using Merlin\Main\Languagues\Ruby\IronRuby.sln: - Can’t open the Microsoft.Scripting project because it imports from “Merlin\Main\Support\SpecSharp.targets” which is not in the repo. - Cryptographic failures when building because “Support\MSSharedLibKey.snk” does not exist. Removing the import statement from “Merlin\Main\Runtime\Microsoft.Scripting\Microsoft.Scripting.csproj” and creating a fake SNK file in the appropriate directory lets me get further, but I still can’t build: - ‘IronRuby.Compiler.Methods’ is inaccessible due to its protection leve Merlin\Main\Languages\Ruby\ClassInitGenerator\ReflectionCacheGenerator.cs 29 77 - ‘IronRuby.Runtime.Calls.BlockDispatcher’ does not contain a definition for ‘MaxBlockArity’ Merlin\Main\Languages\Ruby\ClassInitGenerator\ReflectionCacheGenerator.cs 102 59 Basically a bunch of internal definitions look like they should be public. Am I missing something or did a bad commit slip through? Justin ---

Can you try command line? From Merlin\Main\Languages\Ruby, run “set MERLIN\_ROOT=Path\To\Merlin\Main”, then run “rake compile”. I will try to have SpecSharp.targets moved in the next couple of pushes. Tomas: Do we still need the second copy of SpecSharp.targets in Merlin/Main/Languages/Ruby? Also, can I delete IronRuby.sln (leaving only Ruby.sln). If we don’t need the SpecSharp.targets, I’ll move it from Support back to Main, delete the one in Ruby and update references. JD ---

FYI, Jim (I believe) and I are starting to work out of Git primarily, so we’ll be forced to iron out these kinks. Also, preserving commit information between git and tfs is a goal, so no more of the “sync with tfs” commits … you’ll see the actual msg/author … and we’ll have to get a reliable continuous integration server. Just a heads up that though it’s painful now, it’s going to get much better soon, and everyone to be on the same playing field. ~js ---

Thanks for the hint - I am able to build from the command line.
