Yes, I suspect you have a mismatch between the version of Haddock on your system and the version of Haddock used to produce the interfaces. Try upgrading GHC. Cheers, Simon

Trying to invoke Haddock with --read-interface=c:\ghc\ghc-6.0\doc\html\base\base.haddock

Initially I get a stack overflow, so I added: +RTS -K2M -RTS ...

and now I get: Fail: end of file Action: Data.Binary.getWord8

Is the --read-interface option specified correctly? This is where my GHC installation is, and the base.haddock file exists in there. I assume this is the interface file.

Is this a compatibility problem? i.e. haddock file distributed with GHC 6.0 too old for Haddock 0.6?

- why doesn't it know what Int, String, Float, IO, Monad, Show, etc are? What invocation option do I need to ensure it links to Prelude/hierarchical-library stuff? (I think it's --read-interface; must I generate interface files for the Prelude and libraries though?)

You get the interfaces for the libraries with a GHC installation. Just use the --read-interface flag to tell Haddock about them.

Cheers, Simon
