I am trying to install EclipseFP on the version of Eclipse: Mars Release (4.5.0) on Mac OS Yosemite 10.10.5.
As long as the Haskell perspective appears, nothing special for the Haskell language works (syntax highlighting, hoogle search, etc.)
Here are my Eclipse settings:
And it seems that the problem is that not all the necessary packages can be compiled (but I am sure that this is the main reason)
For example, when I click the Install from Hackage button in the Haskell helper executables, it tries to compile it, but it doesn’t work due to ghc-pkg-lib-0.3:

Can someone please help me?
