Error with new agent

Keymaster

It is a very common error any one will face during developing a new agent or protocol for ns2.
It means you somewhere did a mistake in while patching ns2 files.

First, Understand the basic tutorials of ns2 for creating a new agent for ns2.

Start with “chapter VII -A new protocol for ns” of Marc Greis’ Tutorial

Hi Charles,

I have made the following changes in ns-default.tcl, ns-packet.tcl, packet.h, ns-agent.tcl, Makefile.in

Makefile.in

VanetCR/vanetcr.o VanetCR/vanetcr_accdb.o VanetCR/vanetcr_myheard.o
VanetCR/vanetcr_nghbdb.o VanetCR/vanetcr_sspdb.o

ns-default.tcl

Agent/VanetCR set packetSize_ 1000 ;# for VANETCR added May 5th, 2009
Agent/VanetCR set jitterFactorRBC_ 0.0001
Agent/VanetCR set jitterFactorRev_ 0.0002
Agent/VanetCR set sig_delay_ 0.003255
Agent/VanetCR set verif_delay_ 0.00762
Agent/VanetCR set lastheard_interval_ 1
Agent/VanetCR set statinterval_ 0.01

ns-packet.tcl

# Wireless:
ARP # Address Resolution Protocol, network wireless stack
GAF # Geographic Adaptive Delity, for ad-hoc networks
LL # network wireless stack
LRWPAN # zheng, wpan/p802_15_4mac.cc
Mac # network wireless stack
VanetCR # Added for Vanet on May 5th, 2009

packet.h

name_[PT_VANETCR]= “VanetCR”; //Added for VANETCR on May 5th, 2009
static const packet_t PT_VANETCR = 61; //for VANETCR May 5th, 2009

After Modifications

I execute the following commands to recompile

touch common/packet.cc
./configure
make clean
make

But Still I am getting the error I posted

[root@localhost usman-practice]# ns abc.tcl 14 10 25

num_nodes is set 150
INITIALIZE THE LIST xListHead
SORTING LISTS …DONE!
ns: _o2415 start-statdump:
(_o2415 cmd line 1)
invoked from within
“_o2415 cmd start-statdump”

invoked from within
“catch “$self cmd $args” ret”
invoked from within
“if [catch “$self cmd $args” ret] {
set cls [$self info class]
global errorInfo
set savedInfo $errorInfo
error “error when calling class $cls: $args” $…”
(procedure “_o2415” line 2)
(SplitObject unknown line 2)
invoked from within
“_o2415 start-statdump”

Something I noticed is that even when I comment out the ns-default.tcl definitions I did, I get the same error. So my definitions are having no effect.

So maybe that is the place I am doing something wrong.

Can you please have a look at it?

While compiling NS2-2.28 does not give any error, but when I use antsense under tcl as protocol it stops with the following error.
