mod_hello_world not running #3032

Closed shaggi7 closed 5 years ago

shaggi7 commented 5 years ago

Hi, I am making a custom module following the tutorial https://docs.ejabberd.im/developer/extending-ejabberd/modules/

I have build a new ejabberd instance from source just today . Here are the steps I did

  1. Made a file mod_hello_world.erl and copied the code from tutorial in it.
  2. Saved this file in "ejabberd-master/src" folder .
  3. sudo make install
  4. Succesfully created .beam file in the "ejabberd-master/bin" folder .
  5. Updated the ejabberd.yml file as follow: 
    mod_vcard: {}
mod_vcard_xupdate: {}
mod_version:
show_os: false
mod_hello_world: {}

    now when i am running the the command "ejabberdctl live" I am getting this abrupt behaviour :

    
$ ejabberdctl live
--------------------------------------------------------------------

IMPORTANT: ejabberd is going to start in LIVE (interactive) mode. All log messages will be shown in the command shell. You can interact with the ejabberd node if you know how to use it. Please be extremely cautious with your actions, and exit immediately if you are not completely sure.

To exit this LIVE mode and stop ejabberd, press: q(). and press the Enter key

To bypass permanently this warning, add to ejabberdctl.cfg the line: EJABBERD_BYPASS_WARNINGS=true Press return to continue

Did you mean mod_disco_opt?


What step did i miss or overdo? Please help.

Not a bug.

Hi @zinid But when everything goes right when compiling . Why just adding it to the ejabberd.yml file is creating errors.

See this stackoverflow page: https://stackoverflow.com/questions/56797931/error-when-creating-custom-module-for-ejabberd

I have done this only still it is making problems. This is important @zinid. Please help.

Because ejabberd doesn't see your BEAM file.

I also will probably never understand why everyone goes the hardest way possible. This is how you MUST develop for ejabberd (and how I do it): 1) clone ejabberd repo: git clone https://something-something/ejabberd 2) cd ejabberd 3) put mod_foo.erl into src directory 4) ./autogen.sh && ./configure --something-something && make 5) create ejabberd.yml 6) run ejabberd: erl +K true -pa ebin -pa deps/*/ebin -name ejabberd -s ejabberd
