Wait, 'gazillion of dependencies'? If you have the extralibs bundle built, there are only three dependencies to take care of - a recent Cabal library - HTTP - zlib Of course, downloading and building them manually may take half an hour or so, but it's time well spent, cabal-install makes playing around for ten minutes with some other package so much easier. And of course, as has already been mentioned, there's now a bootstrap.sh included which takes care of the above dependencies for you. ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

You typically need HTTP and zlib. Perhaps cabal-install could have it's own minimal implementations to be standalone? However I don't find needing to cabal build and install 2 packages to be so difficult. And once you have cabal-install, you've got it ;-) It should be able to update itself. Maybe adding cabal-install to the ghc packaging solves all the problems, then they just need zlib and http in the main distribution.

There's a bootstrap.sh file in root of the cabal-install that can do this automatically. I've also improved the bootstrap.sh script for unix users. Feedback as to whether it still works on everyone's unix flavor would be much appreciated. http://darcs.haskell.org/cabal-install/bootstrap.sh It's slightly smarter about not re-installing things that are already installed. It should have rather better error handling too. In fact I've heard reports that this new one even works on Windows, though only for the people with MSYS of course.

Hmm. That's interesting. As we do in the distro tools, for example,
makedepends=('ghc=6.10.1' 'haskell-http4000' 'haskell-zlib')
http://repos.archlinux.org/viewvc.cgi/community/devel/cabal-install/PKGBUILD?revision=1.1root=communitypathrev=CURRENT
So the distro packaging tools already have the 'implicit set' of things
we know are on the system if ghc is on it too.

Re: [Haskell-cafe] runghc Setup.hs doitall
On a similar note, would it not be nice if cabal install understood about platforms and could tell you straight away that a package won't install under e.g. windows, rather then spending ages trying and then failing because a package tries to run a unix command? I always get a bit annoyed trying to do anything in windows with Haskell libraries, at the very least I'd like it to be clear from the start that something won't work (if it's by design) so I don't waste time trying. Ideally the hackage website would even allow you to filter packages by the OS you're using and would remove packages that won't build on that OS (by recursively checking dependencies too). -- From: Duncan Coutts duncan.cou...@worc.ox.ac.uk Sent: Sunday, January 18, 2009 6:20 PM To: Sebastian Sylvan sebastian.syl...@gmail.com Cc: Jeff Wheeler j...@nokrev.com; haskell-cafe@haskell.org Subject: Re: [Haskell-cafe] runghc Setup.hs doitall On Sun, 2009-01-18 at 16:48 +, Sebastian Sylvan wrote: Doesn't work on windows. http://haskell.org/~duncan/cabal/cabal.exe It's not the latest version but you can use it to self-update.

We're pretty near to that. It does understand platforms. What we lack is in the information that it does not work. We can get it in two ways. One is if we cannot find sh.exe then we know straight away that all configure based packages will not work. We should be able to do similar things for packages that need C libs headers etc that we cannot find. We should only need manual additional info for a few packages.

Yes, we should be able to use the same info on hackage as in cabal-install. So, as usual the limiting factor is the number of people hacking on the infrastructure.
