All Haskell packages of good repute live on hackage.haskell.org. http://hackage.haskell.org/cgi-bin/hackage-scripts/package/Cabal http://hackage.haskell.org/cgi-bin/hackage-scripts/package/HTTP http://hackage.haskell.org/cgi-bin/hackage-scripts/package/zlib

You can get these listed packages (Cabal, HTTP and zlib) in Hackage ( http://hackage.haskell.org/ ).

Cabal itself is a special case; you need the same version of Cabal already installed to install it via Cabal... Just run "make" to bootstrap it, IIRC. -- brandon s. allbery [solaris,freebsd,perl,pugs,haskell] allbery@kf8nh.com system administrator [openafs,heimdal,too many hats] allbery@ece.cmu.edu electrical and computer engineering, carnegie mellon university KF8NH

Cabal managed to bootstrap just fine when installed with runhaskell Setup.hs ... as usual on my windows machine. (and running make would have been a problem). But to install cabal-install (the command line interface), you have to install cabal (the library) first. I assume that in the future, ghc will include cabal-install? Until then, it would be nice to have some ad-hoc solution to add cabal-install to a fresh installation of ghc (e.g. a tarball containing cabal-install and it's dependencies and a build script, or a script which downloads said dependencies). Currently, people have to learn dependency chasing and manual hackage/cabal installation just to install cabal-install, which does a great job at making this skill useless. Apropos cabal-install: can i make it build documentation during the installation process and store them in some central location? Tillmann

I also wondered about that. Maybe a '--haddock' flag for 'cabal install' ?
Everyone seems to ask the same (me too). See Ticket #206 (http://hackage.haskell.org/trac/hackage/ticket/206). Additional comments count as priority bumper! Cheers Ben

So! Who wants to implement it? :-) Volunteers please line up over here. Duncan

Note that Eric is talking about cabal-install, not the Cabal library package.

The Cabal library package always bootstraps using its own source code. It does not need any existing version. Despite the bootstrapping it is just an ordinary Cabal package. It can be configured and built in the standard way using runhaskell or cabal-install.
Just run "make" to bootstrap it, IIRC.
Though that also works. Duncan
