Hello,
I am trying to implement a new Congestion control protocol on ns-2.32.
I have installed ns2.32 on a ubuntu 7.10 (2.6.22-14)
The Simulator has been correctly installed and the build has been
validated successfully.
While integrating the protocol is ns2, I have ensured that the
following files are appropriately modified :-
/common/packet.h, /tcl/lib/ns-packet.tcl, /tcl/lib/ns-default.tcl,
/trace/trace.cc . The Makefile has been modified to accommodate my
protocol.
When I run make after the above mentioned modifications I get the
following warning messages.

The rest of the make process finishes normally.
I would like to know why I am being faced with these warnings. When I
run the tcl script, I get a few warnings which say that variables
haven't been declared/Initialized and I get a Floating Point
Exception (Core Dump).
Could you tell me where I am going wrong? Is there some step which I
am missing out on, or any change which has not been implemented?
In addition, it would be helpful if someone who has worked on a
similar protocol could help me out in implementing my protocol.
Thanks in advance,
Varun
