Good morning, The Cabal User manual link is: http://www.haskell.org/cabal/release/cabal-latest/doc/users-guide/ I'm right behind you, I'm working on Yesod on a Windows Vista PC. Wish us both luck ----- Original Message ----- From: Tom Murphy To: Antoine Latter Cc: beginners@haskell.org ; Daniel Fischer Sent: Wednesday, April 06, 2011 12:40 AM Subject: Re: [Haskell-beginners] Happstack dependency problems It requires unix-compat to build. What does "cabal install unix-compat" give you? The same error. But... If that's what's breaking you can try "cabal install unix-compat-0.1.2.1" and then "cabal install happstack-util". Version 0.1.2.1 appears to be the most recent version of unix-compat that doesn't specify version bounds on the unix package, which is what you're having trouble with. This worked, then "cabal install happstack" worked perfectly(!) Can anyone point me to a tutorial which explains basics of cabal? I'm trying to navigate it, without understanding version bounds, or really anything related to how cabal handles versions of dependencies. Thank you for the help!
