Hmmm... $ cabal update $ cabal install hakyll Resolving dependencies... cabal: dependencies conflict: ghc-6.12.3 requires unix ==2.4.0.2 however unix-2.4.0.2 was excluded because ghc-6.12.3 requires unix ==2.4.1.0 $ Any advice (other than upgrading to 7.0.3, which is not an option at the moment)? -- -KQ

Any advice (other than upgrading to 7.0.3, which is not an option at the moment)?

You can run the build with verbose output (--verbose=3) and get more details about why the impossible dependencies were required, or you can build your application (whatever relies on hakyll) with cabal-dev -- I've been able to build hakyll that way on my machine with ghc-6.12.3, so I suspect there is some unexpected dependency in your local package db that is causing cabal to make a series of undesirable version selections. --Rogan

No joy: hakyll itself requires unix 2.4, so the following are discarded: unix-2.0, 2.2.0.0, 2.3.0.0, 2.3.1.0, 2.3.2.0, However, that's the only unix discard before the error occurs somewhat later on, only now the error is not with unix but with array (which is not discarded by anything): ... selecting text-0.11.0.5 (installed or hackage) and discarding text-0.11.0.0, 0.11.0.1, 0.11.0.2, 0.11.0.3, 0.11.0.4, 0.11.0.6 and 0.11.0.7 selecting deepseq-1.1.0.2 (installed or hackage) and discarding deepseq-1.1.0.0 and 1.1.0.1 selecting QuickCheck-2.4.0.1 (installed or hackage) and discarding QuickCheck-2.1, 2.1.0.1, 2.1.0.2, 2.1.0.3, 2.1.1, 2.1.1.1, 2.1.2, 2.2, 2.3, 2.3.0.1, 2.3.0.2 and 2.4 selecting cabal: dependencies conflict: ghc-6.12.3 requires array ==0.3.0.2 however array-0.3.0.2 was excluded because ghc-6.12.3 requires array ==0.3.0.1 $ Its starting to look like there's something very wrong with cabal databases. My first thought is to remove my local version, but I'm hesitant because I do have other haskell work I'm in progress on that isn't broken and I don't want to break it. :-)

No joy there either. There were some preliminary package version complaints that I tried to resolve, but the end result is: $ cabal install cabal-dev Resolving dependencies...

Kevin, what version of cabal install are you using? I ask because prior to the 1.10.* version series, cabal would have a much harder time "correctly" choosing versions of dependencies, which at least for me often manifested as such confusions in caba regarding selecting versions. Prior to said cabal version the solution I'd often do is figure out what the "transitive " dependencies were, recompile them together, iterate that, and that would eventually make the problems go away. point being: the issue is probably conflicting versions of the same libraries are being used by different libraries that are among the dependencies, and cabal is getting confused On Wed, Apr 20, 2011 at 7:34 PM, Rogan Creswick wrote:

Is it safe to upgrade cabal-install and the cabal library or are those part of the GHC package and I'll end up making things even worse? I may have corrupted libraries; I think a re-install is in order soon, but I've been avoiding that until I get to the end of my current activities. -KQ P.S.

It is safe to do this. You will probably need to specify the full version, since despite being included in the latest haskell platform, cabal-install-0.10.x is in the list of things that cabal won't install automatically. (in the same way that it selects versions of parsec...) $ cabal-install Cabal-1.10.1.0 then $ cabal-install cabal-install-0.10.2 should do it.

It doesn't seem to do this anymore for parsec. The preferred-versions now look like this: base < 4 cabal-install < 0.10 network < 2.2.3 || >= 2.2.4 Or am I looking at the wrong thing? Erik

Oh, interesting. I think you're looking at the right thing. I haven't checked it since cabal-install-0.10 came out (I have the hardest time finding that url...). --Rogan

This no longer points to a hakyll problem, not even a cabal problem per se. This is a problem with package inconsistencies you already have; cabal merely does garbage-in garbage-out. The output of "ghc -v" will display wonders. The output of "ghc-pkg list -v" will also be of help. If you are interested in not treating package databases as a black box plug-and-play appliance that "just works" (clearly, it doesn't), see my http://www.vex.net/~trebla/haskell/sicp.xhtml
