EclipseFP doesn't working

I am trying to install EclipseFP on Eclipse version: Mars Release (4.5.0) on Mac OS Yosemite 10.10.5.

While Haskell perspective is appeared, nothing special for Haskell language is not working (Syntax highlight, hoogle search & etc...)

Syntax highlight Hoogle Search

Here is my Eclipse Preferences: Eclipse preferences

And it seems that problem is that not all necessary packages could be compiled (But sure that this is the root cause)

For example, when I am pressing button "Install from Hackage" in the Haskell helper executables it is trying to compile it but fails because of ghc-pkg-lib-0.3:

buildwrapper-0.9.1 depends on ghc-pkg-lib-0.3 which failed to install.
ghc-pkg-lib-0.3 failed during the building phase. The exception was:

Could somebody please help me?

Solution

  • Because of frequently changes happens in EclipseFP and BuildWrapper, they have stopped supporting these 2 project and should use some Leskah too have an IDE http://jpmoresmau.blogspot.com.tr/2015/05/eclipsefp-end-of-life-from-me-at-least.html
