[erlang-questions] running sample progs for MGC and MG
Thu Jan 24 11:36:49 CET 2008
I was using putty from my local windows machine to connect to linux server
and then running this sample application.....
but when i ran this script from linux sever itself (FC8)....it did show
now it want to display GUI from my local windows machine running this appl
on putty...for this i am trying to download an interface b/w linux and
hoping that it would open the GUI from my local windows m/c....
Second question is that - I am looking into erl_interface library
now when you say atleast one erlang node should be running ...do you mean
that anyways i will have to use Erlang in building some application (
Start Media Gateway Controller) and then if i want to start Media Gateway
....i can use my C application to start it and then making MG communicate
with MGW via erl_interface library using C....
Actually, i am bit hazy about this at this moment...
Could you kindly throw more light on that...
Appreciate your help...

I built the stack doing following in FC 8 :
./configure --disable -sctp
Now i want to test MGC and MG running examples at follwoing location
i tried to execute megaco_simple_mgc.erl
following these commands:
erl -pa ../../../megaco/ebin -s megaco_filter -s megaco
but getting the error :
1> Application initialization failed: no display name and no $DISPLAY
Error in startup script: no display name and no $DISPLAY environment
Question1 : what should the value with which env value DISPLAY be set
DISPLAY is environment variable, which contains address and display number
of your X server. Megaco sample progs have some GUI to trace megaco
messages. It seems that you ran stack not in X environment, or under
Question2: these sample applications are made in erlang...is it possible
to use c/c++ or some other language to use APIs/Functionalities of Megaco
There is erl_interface library to interact between erlang node and C/C++
applications, but it is necessary to run one erlang node for this.
