[ns] Error in creating new agent

[Usman Amin]

Hi

I added the following definitions in *

ns-agent.tcl*

Class Agent/VanetCR -superclass Agent

Agent/VanetCR instproc init args {

         $self next $args
}

Agent/VanetCR set sport_   0
Agent/VanetCR set dport_   0

Now the following error is coming.


*Error*

[root at localhost VanetCR]# ns b_univ_twm_active_suicide_usman.tcl 10 2 20
num_nodes is set 150
INITIALIZE THE LIST xListHead

    # set the logtarget for every agent
    $..."
    (file "b_univ_twm_active_suicide_usman.tcl" line 343)
[root at localhost VanetCR]#

Can anybody help.

 Hi

I have NS2.33 running on FC9 in VMWARE. I have to create a new agent.

I have made the following changes in the below listed files

*Makefile*

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
make
make clean
configure


*ERROR*

[root at localhost ns-2.33]# ns
ns:
[code omitted because of length]
: invalid command name "Agent/VanetCR"
   while executing
"Agent/VanetCR set packetSize_ 1000    "

 the strange thing is as soon as I make this change in ns-default.tcl. All
other tcl files also stop working and the error I listed before is
returned.

Any help inthis regard will be highly appreciated.

Thanks & Regards,

Usman
