[ns] Why I cannot declare member functions ???

[Adriano Galati]

Hi,
I am trying to extend ns2 and when I compile my files with make I get

In file included from dtn/DTNAgent.h:19,
from dtn/DTNAgent.cc:15:
dtn/routes.h: In constructor `LinkInfo::LinkInfo()':
dtn/routes.h:16: warning: `LinkInfo::busyTo_' will be initialized after

dtn/DTNAgent.cc:37: error: expected unqualified-id at end of input
make: *** [dtn/DTNAgent.o] Error 1
-bash-3.00$

Does anybody knows the reason or has any clue ??
Any help would be great,
Cheers,

[ns] Segmentation Fault extending ns2

[Adriano Galati]

Hi,
I have extended ns2 for dtn simulations.
I have also created my classes for routing.
I have written my tcl file, see below, and I simply get a segmentation 
fault, without any explanation...
Does anybody have suggestions or got similar problem???
Thank you in advance,
Adriano

# Create a simulator object
set ns [new Simulator]

#Create nodes
set node1 [$ns node]
set node2 [$ns node]

#Create the agent for the first node
set dtn1 [new Agent/DTNAgent]

#Create another Agent for the second node
set dtn2 [new Agent/DTNAgent]

#attach the agents to the nodes
$ns attach-agent $node1 $dtn1
$ns attach-agent $node2 $dtn2

#Set local region
$dtn1 region "REGION1"
$dtn2 region "REGION2"

#Setup routing table
$dtn1 add "REGION2" $dtn2 1 1 1500
$dtn2 add "REGION1" $dtn1 1 1 1500

[ns] segmentation fault extending ns2 because of more output channels: how to fix it???

[Adriano Galati]

Hi everybody,

I am extending ns2 and below is my script tcl.
I have realized that my tcl script works only with one output stream. 
For example, If at the script below I take off the "open a file" part 
and the "puts" function in the finish{} then the tcl script works.
Any idea?
Thanks
Adriano

# Create a simulator object
set ns [new Simulator]

#Open a file
set f [open out.tr w]
$ns trace-all $f

# Open a nam trace file
set nf [open out.nam w]
$ns namtrace-all $nf

# Define a 'finish' procedure
proc finish {} {
   global ns f nf
   $ns flush-trace
   close $f
   close $nf

  puts "Starting nam..."
   exec nam out.nam &
   exit 0
}
