[Haskelldb-users] Bug: overlapping instances in HDBRec.hs

[Volker W. <po...@vo...>]

Hi

I get the following compiler error:

Overlapping instance declarations:
  In module Database.HaskellDB.HDBRec: Database.HaskellDB.HDBRec.HasField f (RecCons f a r)
  In module Database.HaskellDB.HDBRec: Database.HaskellDB.HDBRec.HasField f (RecCons g a r)

Overlapping instance declarations:
  In module Database.HaskellDB.HDBRec: Database.HaskellDB.HDBRec.SelectField f (RecCons f a r) a
  In module Database.HaskellDB.HDBRec: Database.HaskellDB.HDBRec.SelectField f (RecCons g b r) a

The compiler flag -fallow-overlapping-instances is needed. I'm not sure
what triggers the error, since the compiler doesn't tell.

Bye
