[Haskell-cafe] Haskell + emacs + Ghc-mod 4.0.1

Thu Apr 3 13:26:48 UTC 2014

Hello,
I upgrade my emacs configuration with latest ghc-mod and all of sudden
nothing works (again).
When I try to load a .hs file from a project I got the first line
highlighted with the error "cannot satisfy -package spec" and I cannot got
type, info or doc from that file. Also I do not have anymore syntax errors
highlighting I used to see.

Any help greatly appreciated. I would also appreciate any pointer
explaining how to setup and maintain a proper Haskell dev environment.
Haskell is not the language I use at day work but I have been using it for
years and every so often my emacs configuration is broken and I have a hard
time getting it back to sane state.

Thanks in advance
Arnaud

Here is my emacs configuration:

;; haskell coding
(require 'haskell-mode)
(require 'haskell-cabal)

(autoload 'ghc-init "ghc" nil t)

(add-hook 'haskell-mode-hook (lambda () (ghc-init)))

(eval-after-load "haskell-mode"
  '(progn
     (define-key haskell-mode-map (kbd "C-,") 'haskell-move-nested-left)
     (define-key haskell-mode-map (kbd "C-.") 'haskell-move-nested-right)
     (define-key haskell-mode-map (kbd "C-c v c") 'haskell-cabal-visit-file)
     (define-key haskell-mode-map (kbd "C-c C-c") 'haskell-compile)
     (define-key haskell-mode-map (kbd "C-x C-d") nil)
     (setq haskell-font-lock-symbols t)))

(add-hook 'haskell-mode-hook 'turn-on-haskell-decl-scan)
(add-hook 'haskell-mode-hook 'turn-on-haskell-indentation)

(eval-after-load "which-func"
  '(add-to-list 'which-func-modes 'haskell-mode))

(eval-after-load "haskell-cabal"
    '(define-key haskell-cabal-mode-map (kbd "C-c C-c") 'haskell-compile))

Here is the output of ls -l ~/Library/Haskell/bin:
