Yes, EclipseFP is alive, and I'm the maintainer. Yes, there are sometimes issues with installing scion due to the numerous dependencies. No, don't give up!!

You don't need to build scion yourself, usually. The Java plugins include the scion sources and build it internally, setting the proper Cabal flags. If you want to build scion yourself, you need to specify that you use Cabal 1.8: cabal install -fcabal_1_8 should do the trick.

There are also forums on sourceforge that I keep an eye on so you can post questions there too!

Hope it helps!

Hello,

 I tried to install EclipseFP using instructions on http://eclipsefp.sourceforge.net/, nevertheless, without any success - after downloading scion I cannot build it

> cabal install
Resolving dependencies...
cabal: dependencies conflict: ghc-6.12.3 requires Cabal ==1.8.0.6 however
Cabal-1.8.0.6 was excluded because scion-0.1.0.6 requires Cabal ==1.6.*

Running Setup.hs through runhaskell seems not to work as well:
> runhaskell Setup.hs configure
Configuring scion-0.1.0.6...
Setup.hs: At least the following dependencies are missing:
AttoJson >=0.5.2,
binary ==0.5.*,
derive -any,
ghc-paths ==0.1.*,
ghc-syb -any,
ghc-syb-utils -any,
hslogger ==1.0.*,
list-tries -any,
multiset >=0.1 && <0.3,
uniplate -any

Even if, for instance:
> cabal info binary
* binary           (library)
   Synopsis:      Binary serialisation for Haskell values using lazy
                  ByteStrings
   Latest version available: 0.5.0.2
   Latest version installed: 0.5.0.2

Is there any chance to make it install or should I give up?

Dusan
