<br>
<br><font size=2 face="sans-serif">I was using putty from my local windows

<br>
<br><font size=2 face="sans-serif">but when i ran this script from linux

<br>
<br><font size=2 face="sans-serif">now it want to display GUI from my local

an interface b/w linux and windows i.e </font>

<br><font size=2 face="sans-serif">ReflectionX</font>
<br>
<br><font size=2 face="sans-serif">hoping that it would open the GUI from
my local windows m/c....</font>
<br>
<br>
<br><font size=2 face="sans-serif">Second question is that - I am
looking into </font><font size=3>erl_interface library </font>
<br>
<br><font size=2 face="sans-serif">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....</font>
<br>
<br><font size=2 face="sans-serif">Actually, i am bit hazy about this at
this moment...</font>
<br>
<br><font size=2 face="sans-serif">Could you kindly throw more light on
that...</font>

Hi All,</font><font size=3> <br>
</font><font size=2 face="sans-serif"><br>
I built the stack doing following in FC 8 :</font><font size=3> <br>
</font><font size=2 face="sans-serif"><br>
./configure --disable -sctp</font><font size=3> <br>
</font><font size=2 face="sans-serif"><br>
make all</font><font size=3> <br>
</font><font size=2 face="sans-serif"><br>
make install</font><font size=3> <br>
</font><font size=2 face="sans-serif"><br>
Now i want to test MGC and MG running examples at follwoing location</font><font size=3>
<br>
</font><font size=2 face="sans-serif"><br>
/home/j.bhanot/Download/H.248/otp_src_R12B-0/lib/megaco/examples/simple</font><font size=3>
<br>
</font><font size=2 face="sans-serif"><br>
i tried to execute megaco_simple_mgc.erl</font><font size=3> <br>
</font><font size=2 face="sans-serif"><br>
following these commands:</font><font size=3> <br>
</font><font size=2 face="sans-serif"><br>
erl -pa ../../../megaco/ebin -s megaco_filter -s megaco</font><font size=3>
</font><font size=2 face="sans-serif"><br>
%% megaco_simple_mgc:start().</font><font size=3> <br>
</font><font size=2 face="sans-serif"><br>
but getting the error :</font><font size=3> <br>
</font><font size=2 face="sans-serif"><br>
1> Application initialization failed: no display name and no $DISPLAY
environment variable</font><font size=3> </font><font size=2 face="sans-serif"><br>
Error in startup script: no display name and no $DISPLAY environment variable</font><font size=3>
<br>
</font><font size=2 face="sans-serif"><br>
Question1 : what should the value with which env value DISPLAY be set</font>
<br><font size=3><br>
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 another user.
</font>
<br>
<br><font size=2 face="sans-serif">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 stack</font>
<br><font size=3><br>
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.</font>
