I'm running haddock for the first time, via cabal. I get the
following message when i do "runhaskell Setup.hs haddock" on monadLib:
Warning: cannot use package base-2.0:

I do have c:/ghc/ghc-6.6/doc/html/libraries/base/. Is there some way
i can let cabal know how to find it? What is $topdir about?
This is due to the way GHC is installed on Windows, the package database
doesn't have hardcoded pathnames, the idea being that you can move your
GHC anywhere in the filesystem and it will still work.
Unfortunately this means that Haddock can't find the documentation for
the packages.
One workaround is to specify the paths by hand, using Haddock's
--read-interface flag. You're using Haddock via Cabal though, so that
doesn't work too well. The other workaround is to find GHC's
package.conf file and replace the string $topdir with the literal path
("c:/ghc/ghc-6.6" in your case - perhaps you have to append "/doc" for
the haddock fields, though).
I'll file a bug report against Cabal, we should really make this work.
I just noticed we have a bug open for this in GHC's bug tracker:
http://hackage.haskell.org/trac/ghc/ticket/937
So it should get fixed for 6.6.1.
Cheers,
SImon
