Error when trying to start ejabberd after installing mod_apns

[apphipster]

I have a similar issues with the one from here: other issue

I am using ejabberd-16.08 on Mac OS
Here are the steps I do to add the custom module into ejabberd:

• Put the module into ejabberd/src folder.
• In terminal run the command:

$ ./erlc -I ejabberd/include mod_apns.erl

• It results in the the following output in the terminal windows:

mod_apns.erl:8: can't find include file "ejabberd.hrl"
mod_apns.erl:9: can't find include file "logger.hrl"
mod_apns.erl:10: can't find include file "jlib.hrl"

mod_apns.erl:77: Warning: function create_pair/1 is unused
mod_apns.erl:79: Warning: function add_quotes/1 is unused 

• Add the module into config file at /etc/ejabberd/ejabberd.yml

mod_apns:
  address: "gateway.push.apple.com"
  port: 2195
  certfile: "cert.pem"
  keyfile: "key.pem"

• ejabbeerd could not be started. The log file ejabberd.log displays: "Problem starting the module mod_apns for host ..."

• I tried to add the code from bellow to the mod_apns.erl but have no luck with it.

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

Do you have any suggestion? Any help is appreciated.

Hi @apphipster
The second commend on the issue you provided and the README says that you must compile the module with ejabberd itself.

[apphipster]

I managed to compile the module using the following command:
(Attention: the path varies depending on the installed ejabberd version)
$ bin/erlc -I lib/ejabberd-16.08/include/ -I deps/ -pa lib/ejabberd-16.08/ebin src/mod_apns.erl
One warning is displayed:
src/mod_apns.erl:12: Warning: undefined callback function depends/2 (behaviour 'gen_mod')
Add the module into config file at /etc/ejabberd/ejabberd.yml
Restart ejabberd.

In the file jeabberd.log there is an entry:
2016-09-26 12:43:39.575 [info] <0.6670.0>@mod_apns:start:154 mod_apns Has started successfully!

You can also check the presence of the module using the link:
http://localhost:5280/admin/server/macbook.local/node/ejabberd@localhost/modules/
(replace "macbook.local" with your domain)
