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

Question

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?

I have the same problem. Apparently auto-complete-mode does not get loaded. I have to enter (require 'auto-complete) in order to turn it on, and if I had this code to my .emacs it does not run. – Brockway

Answer 1

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)

or, of course, something like "~/.emacs.d/elpa/auto-complete-1.4/dict". and (require 'auto-complete-config) may need to come first. – Orpha

I think the first line (add-to-list) is not needed - after installing auto-complete from marmalade, when I check the value of ac-dictionary-directories (using C-h v) it already has ~/.emacs.d/elpa/auto-complete-1.4/dict – Hydroponics

Answer 2

I had a similar problem. I tried what was suggested in the docs (and by elviejo), but that didn't work. I then tried to do what Pedro suggested, which did work :-) The code added to my init.el file is:

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

(require 'auto-complete) appeared to be mandatory on OS X with Emacs 24 – Capable

@Capable it appeared to NOT be mandatory on OSX with emacs 24 for me – Onieonion

Answer 3

I installed the Auto-Complete which hosted on the github repo. But the installation should resemble that installed by Package.

It seems that u forgot to turn the auto-complete-mode on. Add follow fragment to your .emacs.d file and have a try.

(ac-config-default)

~/.emacs or ~/.emacs.d/init.el – Syllabize
