Hi Robert,

Current version supports only cabal-dev for sandboxing. New version that is about to come out will support cabal for sandboxing as well.

The problem is that installed ghc depends on cabal version being shipped with.
And it looks like it'll stay like that for a while, and until it is solved, you'll depend on cabal being shipped with ghc.

The problematic packages are bins only, so you can
     - build them sandboxed and
       move the bins to .cabal/bin or
    - move/rename your .cabal and .ghc,
      cabal update,
      build cabal-dev and sourcegraph as usual,
      copy the bins to moved/renamed .cabal/bin,
    delete newly created .cabal and .ghc,
    move/rename back your .cabal and .ghc

You can go with 3. also, but for a bit larger project you'll run into cabal-hell, so better to use it.

It is quite comfortable to work in eclipseFP, so I think it is worth some initial troubles. :-)

Best regards,

vlatko

Omit cabal-dev it is not maintained anymore and most of its functionality is part of cabal already (cabal sandbox)

I decided to try out Eclipse with the EclipseFP plug-in for Haskell.

I downloaded Eclipse, and then started to install EclipseFP. At

some point, I got a screen which said that I needed to install

buildwrapper and scion-browser. It offered to install both

of them, and optionally install hoogle, hlint, stylish-haskell,

SourceGraph, and cabal-dev. The option to install the additional

items was pre-checked. I left it checked. The installation of

buildwrapper, etc. took a long time. It seemed to be going well

until I saw the messages below, which say that installing SourceGraph

will likely break several other packages, most of which were part

of the EclipseFP installation.

I am not a complete novice with Haskell but I am a complete novice

with Cabal. I'm not sure what to do. Here are some options I have

considered:

1. Use --force-reinstalls and hope for the best.

2. Try to resolve the problem with Cabal, although I don't know to

do this.

3. Use EclipseFP without SourceGraph and cabal-dev.

4. Use EclipseFP without SourceGraph, but install cabal-dev using

cabal on the command line.

5. Forget about Eclipse altogether, and go back to using vim.

Any advice would be appreciated.

By the way, I am using Haskell Platform 7.6.3.

Here are the messages I saw in the Eclipse console window:
