In celebration of Hackage reachin over 1,000 unique packages, I decided that I would re-visit the problem of attempting to build them on Windows.
I began by removing all existing Haskellness from my PC. I now have a vanilla Windows XP (32-bit) system with Service Pack 3. So, let's see what we can do here...
- Install GHC 6.10.1. As you'd expect, no issues here.
- Now, let's install stream-fusion. First let me ch... woah! What the hell?
OK, it seems that Google is temporarily "broken". (All websites show up as "this site may damange your computer".) Obviously this has nothing to do with Haskell, but it makes navigating Hackage moderately more tedious. Oh well, anyway, where was I?
Ah yes, I already have the tarball for stream-fusion-0.1.1, but I see that the latest release is 0.1.2.1. (Unfortunately, there doesn't appear to be any way to determine what the difference is between the two versions...)
- Right, I've got the tarball for stream-fusion. Now let's see if it will install...
J:\Haskell\unpack> runhaskell Setup configure J:\Haskell\unpack> runhaskell Setup build J:\Haskell\unpack> runhaskell Setup install J:\Haskell\unpack> ghc-pkg list ...stream-fusion-0.1.2.1...
OK, nothing much wrong with that then. :-D
- Hmm, doesn't GHC 6.10.1 now come with Haddock included? I wonder if there's a way to ask Cabal to build the docs for me...
[Grr! Google is still busted.]
Ah, yes there is. OK, let's try this:
J:\Haskell\unpack> runhaskell Setup haddock ... Data\Stream.hs:292:33: parse error on input `!' haddock: Failed to check module: Data.Stream
Uh... OK. So I guess I *won't* build the docs for that one then. :-/ Oh well, maybe it's a one-off failure? Let's try some more packages...
The problem there is that stream-fusion is trying to put documentation on individual data constructor arguments which is not supported by Haddock. David
