Problem starting the module mod_gcm for host localhost

[P-r-a-d-e-e-P]

Hi Doctor,
I've setup ejabberd in Elixir/Phoenix application. Mix.exs has {:ejabberd, "~> 17.9"}. I've also copied mod_gcm.erl in src folder and put the following entry in ejabberd.yml.

mod_gcm:
gcm_api_key: "key"
While starting the phoenix app application stops with following error:

[warn] module 'mod_gcm' doesn't export mod_opt_type/1
[error] Problem starting the module mod_gcm for host localhost
options: [{gcm_api_key,<<"key">>}]
error: undef
[{mod_gcm,start,

[error] ejabberd initialization was aborted because a module start failed.

Hi, @P-r-a-d-e-e-P

I'm sorry, but it seems the notification about this issue somehow got lost in my mail.

You're running an unsupported version of ejabberd. So, I'm afraid, you're not getting this module to work.

Any particular code that needs to be changed in order to make this work for later versions? I'll try fixing it if I can.

@karunreddy30 sorry for the long silence.

You can start from looking at this commit mrDoctorWho/ejabberd_mod_apns@82baa09

I'm sorry, but I don't currently have time to maintain my projects.
