I'm trying to compile GHC 6.8.2 using my existing GHC 6.2, but the
typechecker refuses to compile. The problem seems to be that the hi-boot
files in compiler/typecheck contain some incorrect type signatures. I've
fixed most of them, but TcMatches.hi-boot-6 has slightly stumped me. As
it stands, it says
tcMatchesFun :: Name.Name
-> HsExpr.MatchGroup Name.Name
-> TcType.BoxyRhoType
-> TcRnTypes.TcM (HsBinds.HsWrapper, HsExpr.MatchGroup
TcRnTypes.TcId)
but it should say something like
tcMatchesFun :: Name.Name -> Bool
-> HsExpr.MatchGroup Name.Name
-> TcType.BoxyRhoType
-> TcRnTypes.TcM (HsBinds.HsWrapper, HsExpr.MatchGroup
TcRnTypes.TcId)
Unfortunately, that doesn't work, as it assumes I meant TcMatches.Bool,
so I tried saying Prelude.Bool instead. Now I get the complaint that
Prelude.Bool isn't in scope.
Has anyone else seen this issue? I've looked for answers in the docs and
with Google, but no luck.
I'm running Mac OS 10.3, with GHC 6.2 installed under Fink. I borrowed
the Fink package for GHC 6.8.2 and adapted it slightly so it would
bootstrap from my existing GHC, as the bootstrap code available for
download relies on a later version of my OS. GHC 6.2 can't compile GHC
6.10, which is why I'm going for the earlier version.
Cheers,
Barney.
