Using the stable version
The Emacs front-end is available from stable MELPA. This package should always be compatible with the latest version of ghc-mod from hackage.
To use stable stable MELPA add this to your .emacs:
(require 'package)
(add-to-list 'package-archives
'("melpa" . "http://melpa-stable.milkbox.net/packages/"))
(package-initialize)
With this configuration you can install the Emacs front end from MELPA (the
package is called ghc there, not ghc-mod) and install the
ghc-mod/ghc-modi binaries from hackage by doing:
% cabal update && cabal install ghc-mod
Nix & NixOS
ghc-mod works fine for users of Nix who follow a recent version of the
package database such as the nixos-15.09 or nixos-unstable channel. Just
include the package ghc-mod into your ghcWithPackages environment like any
other library. The Nixpkgs Haskell User's
Guide
covers this subject in gret detail.
Using the development version
The easiest way to hack on ghc-mod is compile it, then add dist/build/ghc-mod
and dist/build/ghc-modi to your PATH and add the elisp/ directory to your
Emacs load-path.
Make sure you're not using the MELPA version of ghc.el otherwise you might get
all sorts of nasty conflicts.
Custom ghc-mod cradle
To customize the package databases used by ghc-mod, put a file called ghc-mod.cradle beside the .cabal file with the following syntax:
temp directory root
package db 1
...
package db n
each package database line is either a path to a package database, or global or user.
IRC
If you have any problems, suggestions, comments swing by #ghc-mod (web client) on Freenode. If you're reporting a bug please also create an issue here so we have a way to contact you if you don't have time to stay.
Do hang around for a while if no one answers and repeat your question if you still haven't gotten any answer after a day or so. You're most likely to get an answer during the day in GMT+1.
