- Error with new agent
usmanHi
I am getting the following error
[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”
As in the error above it is not accepting statdump. It gives similar errors on regbc etc. This shows all the procedures it has to take from the C++ file its not recognizing them.
Now Can this be a definition issue. Because I have defined the C++ files in Makefile.in
I have also made changes in ns-default.tcl, ns-packet.tcl, ns-agent.tcl and packet.h
Can anybody please help?
Thanks
CharlesPandianIt 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
usmanHi Charles,
I have made the following changes in ns-default.tcl, ns-packet.tcl, packet.h, ns-agent.tcl, Makefile.in

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

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?
