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: <terminated> Installing executable SourceGraph Resolving dependencies...
