error in blackholeaodv


Hello NS Users,

I installed ns2.35 , I am trying to
add a new protocol in NS2.
I followed the steps at:
http://acikarsiv.atilim.edu.tr/eng/b...0/172.pdf?show

After applying changes, I did:
$ make clean
$ make

When I run my tcl script then it gives below error.Creating nodes...
