Hi Murphy,
I got a bit confused with the working of messenger. Thanks for the
clarification.
I was trying to run the messenger code (from the link provided by you). I
copied the folder to the following location:
nox/src/nox/coreapps/
The location nox/build/src/nox/coreapps/messenger looks like this, which I
left as it was:
[neha@doorsingdog-dx messenger]$ ls
cacert.pem messenger_la-messenger.lo
__init__.py messenger.py
jsonmessenger.la meta.json
jsonmessenger_la-jsonmessenger.lo _pyjsonmsgevent.la
jsonmsg_event.la
_pyjsonmsgevent_la-pyjsonmsgevent_wrap.lo
jsonmsg_event_la-jsonmessenger.lo pyjsonmsgevent.py
Makefile _pyjsonmsgevent.so
messenger_core.la pyjsonmsgevent_wrap.cc
messenger_core_la-messenger_core.lo servercert.pem
messenger.la serverkey.pem
>From nox/build/src, I did the following:
[neha@doorsingdog-dx src]$ ./nox_core -v -i ptcp: pymessenger
00001|nox|INFO:Starting nox_core

Can you please tell me what I did wrong? The existing messenger.py file was
different from that provided by you. I am confused with what (code files)
to place where. Also, could you please give me an example messaging code
that sends a json message to the controller (so that I get an idea of how
to create a sample sender)?
Regards,
Neha
