filepath broken with Cabal 1.1.6
Hi, For users of Cabal 1.1.6, the currently checked in filepath Setup.hs script won't work - it gives:
runghc Setup.hs configure
Setup.hs:17:30: Couldn't match expected type `UserHooks' against inferred type `Maybe UserHooks' Expected type: Hook a Inferred type: PackageDescription -> LocalBuildInfo -> Maybe UserHooks -> BuildFlags -> IO () In the second argument of `($)', namely `buildHook defaultUserHooks' In the `buildHook' field of a record Can this be fixed? I know the Setup.hs only really serves GHC's purposes, and I think its Ian's work. I also think its possibly the same for other packages? It would be a shame if we make everyone upgrade to have a libary which we've not put in base so they can upgrade it separately... Thanks Neil
Hi
Someone on IRC suggested that removing the type signature is all that
is required to make it work once more.
Thanks
