Emacs auto-complete installed by Package from http://marmalade-repo.org/ doesn't work

autocomplete, elisp, emacs, emacs24, marmalade

Solution

I had this same issue. I fixed it by appending this to my .emacs

/auto-complete/manual.html#Manual_Installation

(add-to-list 'ac-dictionary-directories "~/.emacs.d/dict")
(require 'auto-complete-config)
(ac-config-default)

Problem

I'm new to Emacs and the version is 24. As mentioned in the title, I've installed auto-complete by `M-x package-install` from Marmalade-repo, and the files lies in `~/.emacs.d/elpa/auto-complete-1.4/`. Then I turned Emacs off and opened a new frame, but nothing happens when coding. Do I need some configuration to make it run?
