emacs erc notification don't work

I want to be notified when someone addresses me on irc. But some reason I can't achieve that.

I tried to set the list erc-modules to include notifications like so:

(require 'erc)
(add-to-list 'erc-modules 'notifications)
(erc-update-modules)

It was giving me:

Symbol's value as variable is void: notifications

So then I simply did

M-x customize option
erc-modules

There I clicked the "notifications" options. And the following was saved to my .emacs file:

(custom-set-variables
 ...
'(erc-modules (quote (autojoin button completion fill irccontrols list log match menu move-to-prompt netsplit networks noncommands notifications readonly ring stamp track)))
 ...
 )

But I still have no notifications. By the way, I left the first code block, from above, in .emacs file. Its still at the very bottom of the .emacs file, after everything else.

So my question is how do I set erc to notify me when someone is addressing a message at me?

Thanks in advance for your kind help and time.

Solution

According to the manual ( https://www.gnu.org/software/emacs/manual/html_node/erc/Modules.html ), one method would be to: (1) set erc-modules manually; and, (2) then call erc-update-modules.

My interpretation of that is as follows:

(require 'erc)

(setq erc-modules '(
  autojoin
  button
  completion
  fill
  irccontrols
  list
  log
  match
  menu
  move-to-prompt
  netsplit
  networks
  noncommands
  notifications
  readonly
  ring
  stamp
  track))

(erc-update-modules)

Your other erc settings should be removed.
