Neil, As I upgraded to GHC 6.8.2, I am trying to do full clean and rebuild of Yhc. I am getting an error: ====================================== Getting dependencies for depends/uniplate/Data/Generics/PlateInternal.hs. Unable to open 'depends/uniplate/Data/Generics/.PlateInternal.hs.dep'. Dependencies will not be calculated. "ghc" -i./src/compiler -i./src/libraries/general -i./src/libraries/core -idepends/cpphs -idepends/filepath -idepends/uniplate -i./src/interactive -package mtl -package containers -package pretty -package packedstring -c depends/uniplate/Data/Generics/PlateInternal.hs -o depends/uniplate/Data/Generics/PlateInternal.o Getting dependencies for depends/uniplate/Data/Generics/Uniplate.hs. scons: *** Source `depends/uniplate/Data/Generics/Str.hi' not found, needed by target `depends/uniplate/Data/Generics/Uniplate.o'. Stop. scons: building terminated because of errors. ====================================== SConscript in depends/uniplate does not mention Str. Even if I add it there manually, I end up with error compiling Yhc.Core.Uniplate because of uniplateOnList not in scope, but it is commented out in Data.Generics.UniplateOn If I uncomment it, there is a problem with contexts, etc... Anything happened to Uniplate? Thanks. -- Dimitry Golubovsky Anywhere on the Web
