Hi,
I tried to port some code from ghc 6.2 to ghc 6.4, but I got the
following error
PrelExts.lhs:41:25:
Ambiguous occurrence `map'
It could refer to either `GHC.Base.map', imported from Data.List at
PrelExts.lhs:11:0-15
or `Data.Set.map', imported from Data.Set at
PrelExts.lhs:10:0-14
The following is the first part of the code
module PrelExts where
import Data.FiniteMap
import Data.Set
import Data.List
import IO
There is no problem under ghc 6.2. What should I do?
