How did this happen?

in 6.8.3 at least we could see the exports, with hyperlinks to the actual docs:

Also, #2337 seems to have regressed again, I imagine the cause is probably the same.

I have fixed this problem in Haddock, so we now link to the docs for each export. However, the links sometimes go to the wrong place due to a bug in GHC where the options specified with OPTIONS_HADDOCK seem to go unnoticed. Currently investigating...

HEAD now has:

  * Show re-exported names from external packages again
  This fixes GHC ticket 2746.
  In order to also link to the exported subordinate names of a declaration, we
  need to re-introduce the sub map in the .haddock files.

Ok, so the problem with links that goes to the wrong place is now fixed with this patch (in the HEAD):

Wed Jan  7 00:34:17 CET 2009  David Waern <>        
  * Do not process boot modules
  We should of course not try to produce documentation for boot modules! The
  reason this has worked in the past is that the output of "real" modules
  overwrites the output of boot modules later in the process. However, this
  causes a subtle link environment problem. So let's get rid of this stupid
  We avoid processing boot modules, but we continue to typecheck them.

So that was a Haddock bug and not a GHC one.

Now Char from haskell98 has links to definitions in Data.Char and GHC.Types.

Will tackle CTypes and the likes next.

Module exports now works again, with this patch which is in HEAD:

  * Export modules also when coming from external packages
