Hi again 🙂 Trying to build IR on Mono 2.6.3 on my Macbook (10.6.3). Followed basic instructions and get it to start building but I’m running into the following error on both CasualJim’s Linux branch as well as mainline ironruby git: 21:56:18 zbrown@riemann: ~/Code/ironruby.git/Merlin/Main/Languages/Ruby > rake compile mono=1 > (in /Users/zbrown/Code/ironruby.git/Merlin/Main/Languages/Ruby) * * * ## dlr\_extension * * * ## dlr\_core ## Actions/CallSiteBinder.cs(169,18): warning CS0219: The variable `targetType' is assigned but its value is never used Actions/CallSite.cs(317,17): warning CS0168: The variable`site’ is declared but never used Ast/ExpressionStringBuilder.cs(165,28): warning CS0219: The variable `getIndex' is assigned but its value is never used Ast/ExpressionStringBuilder.cs(166,28): warning CS0219: The variable`setIndex’ is assigned but its value is never used Ast/ExpressionStringBuilder.cs(167,31): warning CS0219: The variable `deleteIndex' is assigned but its value is never used Ast/ExpressionStringBuilder.cs(169,26): warning CS0219: The variable`invoke’ is assigned but its value is never used Ast/ExpressionStringBuilder.cs(170,34): warning CS0219: The variable `create' is assigned but its value is never used Ast/DebugViewWriter.cs(232,28): warning CS0219: The variable`getIndex’ is assigned but its value is never used Ast/DebugViewWriter.cs(233,28): warning CS0219: The variable `setIndex' is assigned but its value is never used Ast/DebugViewWriter.cs(234,31): warning CS0219: The variable`deleteIndex’ is assigned but its value is never used Ast/DebugViewWriter.cs(236,26): warning CS0219: The variable `invoke' is assigned but its value is never used Ast/DebugViewWriter.cs(237,34): warning CS0219: The variable`create’ is assigned but its value is never used Ast/DebugViewWriter.cs(869,18): warning CS0219: The variable `parenthesize' is assigned but its value is never used Compiler/LambdaCompiler.Logical.cs(178,33): warning CS0219: The variable`p’ is assigned but its value is never used Compiler/LambdaCompiler.Unary.cs(111,35): warning CS0219: The variable `labIfNull’ is assigned but its value is never used Compilation succeeded - 15 warning(s) ## dlr\_libs * * * ## dlr\_com Actions/ActionBinder.cs(131,18): warning CS0219: The variable `visType' is assigned but its value is never used Actions/DefaultBinder.Conversions.cs(48,18): warning CS0219: The variable`knownType’ is assigned but its value is never used Actions/DefaultBinder.GetMember.cs(215,26): warning CS0219: The variable `x' is assigned but its value is never used Actions/DefaultBinder.Invoke.cs(261,24): warning CS0219: The variable`instance’ is assigned but its value is never used Interpreter/LightCompiler.cs(915,21): warning CS0219: The variable `handlerContinuationDepth' is assigned but its value is never used Interpreter/LightCompiler.cs(895,17): warning CS0219: The variable`tryStackDepth’ is assigned but its value is never used Generation/ILGen.cs(1188,18): warning CS0219: The variable `isFromFloatingPoint' is assigned but its value is never used Generation/Snippets.cs(115,30): warning CS0219: The variable`coreAssemblyLocations’ is assigned but its value is never used Runtime/DelegateInfo.cs(102,26): warning CS0219: The variable `convertSiteType' is assigned but its value is never used Runtime/DelegateInfo.cs(100,26): warning CS0219: The variable`siteType’ is assigned but its value is never used Unhandled Exception: System.ArgumentException: The field handle and the type handle are incompatible. at System.Reflection.FieldInfo.GetFieldFromHandle (RuntimeFieldHandle handle, RuntimeTypeHandle declaringType) [0x00000] in :0 at Mono.CSharp.AnonymousMethodStorey.MutateField (System.Reflection.FieldInfo field) [0x00000] in :0 at Mono.CSharp.FieldExpr.MutateHoistedGenericType (Mono.CSharp.AnonymousMethodStorey storey) [0x00000] in :0 at Mono.CSharp.TypeCast.MutateHoistedGenericType (Mono.CSharp.AnonymousMethodStorey storey) [0x00000] in :0 at Mono.CSharp.Binary.MutateHoistedGenericType (Mono.CSharp.AnonymousMethodStorey storey) [0x00000] in :0 at Mono.CSharp.If.MutateHoistedGenericType (Mono.CSharp.AnonymousMethodStorey storey) [0x00000] in :0 at Mono.CSharp.Block.MutateHoistedGenericType (Mono.CSharp.AnonymousMethodStorey storey) [0x00000] in :0 at Mono.CSharp.AnonymousExpression+AnonymousMethodMethod.Emit () [0x00000] in :0 at Mono.CSharp.TypeContainer.EmitType () [0x00000] in :0 at Mono.CSharp.AnonymousMethodStorey.EmitType () [0x00000] in :0 at Mono.CSharp.TypeContainer.EmitType () [0x00000] in :0 at Mono.CSharp.RootContext.EmitCode () [0x00000] in :0 at Mono.CSharp.Driver.Compile () [0x00000] in :0 at Mono.CSharp.Driver.Main (System.String[] args) [0x00000] in :0 rake aborted!

I rather have IronRuby working out of the 2.6 tree since there are going to be a few more 2.6 bugfix releases before 2.8 is out. Do you know what bugs from trunk needs to be backported? ---

I’m not sure which bug it is but there is a difference between using ironruby and building ironruby on mono. You should be able to use the [ms.net](http://ms.net) binaries with mono 2.6.3 ## It’s a compiler bug that had been closed once but regressed.
