When I run "cabal install" it says: $ cabal update Downloading the latest package list from hackage.haskell.org Note: there is a new version of cabal-install available. To upgrade, run: cabal install cabal-install If I run "cabal install cabal-install" as it suggests then it appears to do a lot of work, ending with this: ... [33 of 34] Compiling Distribution.Client.List ( Distribution/Client/List.hs, dist/build/cabal/cabal-tmp/Distribution/Client/List.o ) [34 of 34] Compiling Main ( Main.hs, dist/build/cabal/cabal-tmp/Main.o ) Linking dist/build/cabal/cabal ... Installing executable(s) in /home/jdh30/.cabal/bin But when I run "cabal install" again it fails to detect the updated cabal-install correctly: $ cabal update Downloading the latest package list from hackage.haskell.org Note: there is a new version of cabal-install available. To upgrade, run: cabal install cabal-install
With 6.12 it may be that you don't have the cabal-install package installed already, so cabal install won't work.
If that's the case, you'll need to download cabal-install and it's deps and install it using runhaskell Setup.hs configure, runhaskell Setup.hs build ad runhaskell Setup.hs install.
Those "runhaskell" commands don't do anything here. If I use bootstrap.sh then I get: $ ./bootstrap.sh Error during cabal-install bootstrap: Version mismatch between ghc and ghc-pkg If you set the GHC variable then set GHC_PKG too So I do: $ export GHC=ghc-6.12.1 $ export GHC_PKG=ghc-pkg-6.12.1 Then "bootstrap.sh" gets a bit further: $ ./bootstrap.sh Checking installed packages for ghc-6.12.1... The Haskell package 'parsec' is required but it is not installed. If you are using a ghc package provided by your operating system then install the corresponding packages for 'parsec' and 'network'. If you built ghc from source with only the core libraries then you should install these extra packages. You can get them from hackage. Error during cabal-install bootstrap: The Haskell package 'parsec' is required but it is not installed. I cannot install the appropriate libghc6-parsec-dev package from any Debian because they all require GHC =6.8.
That, or wait until 6.12 is considered stable enough to become part of the Haskell platform.
How long will that take?
For reference – I can quite believe that Haskell came out incredibly fast here – it's trivially easy to parallelise haskell programs, and GHC deals with parallelisation well (except for garbage collection unfortunately).
Yeah, I don't believe his Haskell is correct let alone fast. :-) -- Dr Jon Harrop, Flying Frog Consultancy Ltd. http://www.ffconsultancy.com/?e
