Beginner trying to install Haskell support in Eclipse and failing
Hi, I'm using cabal for the first time, and I'm confused. I'm trying to build scion as instructed at http://eclipsefp.sourceforge.net/build.html . I have done: git clone git://github.com/JPMoresmau/scion.git cd scion cabal install I'm now at the point where this tells me the following: Resolving dependencies... cabal.exe: dependencies conflict: ghc-6.10.4 requires Cabal ==1.6.0.3 however Cabal-1.6.0.3 was excluded because scion-0.1.0.2 requires Cabal ==1.8.* && ==1.8.* Some more information: $ cabal -V cabal-install version 0.6.2 using version 1.6.0.3 of the Cabal library $ 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 $ cabal install cabal-install (lots and lots of output, ending with:) Linking dist\build\cabal\cabal.exe ... Installing executable(s) in C:\Program Files (x86)\Haskell\bin $ cabal -V cabal-install version 0.6.2 using version 1.6.0.3 of the Cabal library Help? Thanks, -A
As luck would have it, I ran into the same issue today. I checked the
scion google code website and found a solution. Quick summary: you'll
have to pull changes from the development branch.
Here's a link to the reported issue and the solution:

Hope that helps,

I'm trying to build scion as instructed at http://eclipsefp.sourceforge.net/build.html . I have done:
git clone git://github.com/JPMoresmau/scion.git cd scion cabal install
I'm now at the point where this tells me the following:
Resolving dependencies... cabal.exe: dependencies conflict: ghc-6.10.4 requires Cabal ==1.6.0.3 however Cabal-1.6.0.3 was excluded because scion-0.1.0.2 requires Cabal ==1.8.* && ==1.8.*
That's odd, the .cabal file says if flag(cabal_1_8) build-depends: Cabal == 1.8.* cpp-options: -DCABAL_VERSION=108 else build-depends: Cabal == 1.6.* cpp-options: -DCABAL_VERSION=106 and since you don't have Cabal-1.8.*, it should set the flag to false and try again. Anyway, try setting the flag to false on the command line: cabal install -f-cabal_1_8 or install the hackage package: cabal install scion
Some more information:
$ cabal -V cabal-install version 0.6.2 using version 1.6.0.3 of the Cabal library $ 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 $ cabal install cabal-install (lots and lots of output, ending with:) Linking dist\build\cabal\cabal.exe ... Installing executable(s) in C:\Program Files (x86)\Haskell\bin
Is that directory in your path (and before the directory cabal- install-0.6.2 is in)?
$ cabal -V cabal-install version 0.6.2 using version 1.6.0.3 of the Cabal library
perhaps cabal install cabal-install-0.8.0 (or whatever the latest version working on windows is)
Help?
