[erlang-questions] Erlang + Ejabberd

Hi Team,

I am new to Erlang, I have been trying to install Erlang and Ejabberd on
EC2 ubuntu machine, everything went well till I started compiling some
external modules in ejabberd. It started throwing error "undefined parse
transform 'lager_transform'". I tried everything which is as below :


   1. Did rebar get-deps, make clean, make deps, make install. After this I
   am able to see that lager_transform.beam is made and present in //lib/
   folder.
   2. Checked rebar.config file, it had lager deps on top, which is widely
   suggested, no help even after that.
   3. Added -compile[{parse_tranform},{lager_transform}] on top of module,
   even then their is no luck.

I am really blocked on this, and not able to complete the installation. I
have done this before on fedora with Ejabberd 15.11 and otp 18.2, at that
time it was using p1_logger instead of lager. But now when I am installing
fresh with otp 18.2 and Ejabberd 16.0 or 15.11, I am getting
lager_transform undefined error.

Please suggest and help
