I had the same issue. To fix it, add the following to your module source code after the "export" function:

-ifndef(LAGER).
-define(LAGER, 1).
-endif.

Hi, I'm not sure if this

Hi,

I'm not sure if this would still be helpful, but I encountered the same problem you did. I followed the same tutorial you followed (http://metajack.im/2008/08/28/writing-ejabberd-modules-presence-storms/). I have outlined the steps I took to solve it below:

1. I couldn't get the simple module below to run with the ejabberd-13.12 without the ejabberd_logger error, so I decided to compile ejabberd from source (https://github.com/processone/ejabberd).
2. I added -define(LAGER, 1). to ejabberd/include/logger.hrl
3. Then, I compiled the code below using the command erlc -I ejabberd/include/ -pa ejabberd/deps/lager/ebin mod_test.erl
4. I copied the generated mod_test.beam file to /lib/ejabberd/ebin/.
5. I started ejabberd with the command sudo ejabberdctl start and it worked without the error.

I hope this helps. (FYI - I'm running Ubuntu 13.04).

Cheers.

-module(mod_test).
-behaviour(gen_mod).
-include("logger.hrl").
-export([start/2, stop/1]).
start(_Host, _Opts) ->
	?INFO_MSG("mod_test starting", []),
    ok.
stop(_Host) ->
	?INFO_MSG("mod_test stopping", []),
        ok.
