“undefined reference to `hdr_aodv::offset_'” error in NS 2.35


I am trying to make some improvements on AODV routing protocol using NS 2.35. I have made some changes in aodv.cc and aodv.h file. For making the changes effective, I have made the following three commands from the terminal inside NS 2.35 folder:

1. sudo su

2.make clean

3.make

Now I am having the following error:

trace/cmu-trace.o: In function `CMUTrace::format_aodv(Packet*, int)':
cmu-trace.cc: (.text+0x18b7): undefined reference to `hdr_aodv:: offset_'

What is the solutions of this?

For more clarification I am providing the .cc file link here:

AODV.cc and AODV.h : The file names are aodv.cc, aodv.h .

? Why are you running as root = 'sudo su', when you are building ns2 ?
Most convenient setup is /home/<user>/ns2/ns-allinone-2.3x/.
No ns2 root commands are allowed, except 'make install' and 'cp ns-name /usr/local/bin/'.

Files : Your modified aodv.h is missing.

And the changes are missing, i.e. what did you edit, and which line numbers :
The diff command can generate the changes ...
diff -Naur aodv.cc-orig aodv.cc >> changes-aodv.cc.txt
diff -Naur aodv.h-orig aodv.h >> changes-aodv.h.txt


P.S. : Why the tag "ns2 ns234", when the above says ns-2.35 ?
Surplus tags : "linux command", "networking" (The 'ns2' tag will do.)

Here is the link of modified aodv.cc and aodv,h files. And The file names are aodv.cc and aodv.h. I had mistakenly written AODV.h and AODV.cc
