Thank you Piers, changing mk_mngpdb.inc did the trick. Still, it doesn't build completely. Normally I would have abandoned it by now (I don't *really* need it that badly on NT), but I thought this last error was worthwile looking at/knowing about.
It fails to build isymwrapper.dll, and I boiled it down to this: L:\Work\DotNet\sscli\clr\src\toolbox\isymmanagedwrapper>csc /unsafe+ /checke d- /R:L:\Work\DotNet\mscorlib.dll /nostdlib+ /R:L:\Work\DotNet\mscorlib.dll /target:library objdf\rotor_x86 \AssemblyAttributes.cs objdf\rotor_x86\AssemblyRefs.cs isymwrapper.cs error CS1577: Assembly generation failed -- The system cannot find the path specified. The interesting part is that if I just remove /unsafe+ from the command line above, the code compiles fine. I just don't see what the relationship is between generating unsafe code and the search path for compilation. Cristian
