External module not loaded in Erlang

I am new here in Erlang. I am trying to load library which is hosted on git through rebar3 and been able to compile successfully. Now when I try to run my Erlang application call the main function which actually points to library module function it throws an error in shell 'module could not be loaded'.

I have tried code.get_path() but in that my module is not listed. So I am confused here. Can anyone help me out here ?

    ** Generic server <0.80.0> terminating

It looks like you are pooling smpp34pdu in incorrect manner. It should be as dependency to smpp34, but for some reason it isn't. Easiest solution would be adding smpp34pdu to your deps in reber.config.

smpp34 is also seven years old library, and you might expect some incompatibility issues with rebar3, and/or current version of Erlang (if you are using one). I would recommend cloning both repositories to your own GithHub account and fixing/adressing all issues you encounter. You could upgrade config to rebar3, and add smpp34pdu as dependency to smpp34.
