[Mono-devel-list] Assembly Manipulation Libraries

[Zoltan Varga]

                                   Hi,

  The GetModules problem is now fixed in SVN, but Rail will still not run, since
it uses '\\' for creating directories, which is not portable. The
following patch
fixes that:

<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
diff -r orig-src/rail/RAIL/MSIL/TypeResolver.cs rail/RAIL/MSIL/TypeResolver.cs
109c109
< 			assmBldr =
AppDomain.CurrentDomain.DefineDynamicAssembly(assemblyName,access,"..\\");

---
> 			assmBldr = AppDomain.CurrentDomain.DefineDynamicAssembly(assemblyName,access,"..");

< }
\ No newline at end of file

diff -r orig-src/rail/RAIL/Reflect/Assembly.cs rail/RAIL/Reflect/Assembly.cs
1305c1305
< 								if (i != (implMapRow.MemberForwarded & 0x00FFFFFF))

---
> 								if (i != ((uint)implMapRow.MemberForwarded & 0x00FFFFFF))

<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<

The second change is needed to work around:
