I figured this out: I removed all my user state (~/.eclipse, my eclipse workspace, ~/.cabal, ~/.ghc); removed my Debian stable installation of ghc and cabal; deleted some old nixpkg versions of ghc and cabal I had lying around; and then installed the latest haskell platform. Everything works fantastically now. Thanks JP.

I got around one of these (hoogle vs scion-browser) by specifying both to cabal-install.

Otherwise you can just copy your project in your workspace, and go NEw -> Haskell Project, and enter the name. EclipseFP will not overwrite any existing file so will use your existing Cabal file and all your sources.JP Moresmauhttps://www.blogger.com/profile/09964251063221757176noreply@blogger.comtag:blogger.com,1999:blog-37404288.post-87895220468603710262014-06-30T15:03:36.192+02:002014-06-30T15:03:36.192+02:00How do I import an existing cabal project?How do I import an existing cabal project?Lemaohttps://www.blogger.com/profile/07616720150048806049noreply@blogger.comtag:blogger.com,1999:blog-37404288.post-42259882436070777172014-06-12T18:20:10.992+02:002014-06-12T18:20:10.992+02:00Hi, i'm trying to install eclipsefp.
