[ndnSIM] GDB not Found

[sai gautams]

Hello all,
I'm trying to debug my code using gdb but for some reason it doesn't work.
Can anyone help me point out the problem here.

~/ndnSIM/ns-3$ ./waf --run RandomApplication --command-template="gdb --args
%s <args>"
Waf: Entering directory `/home/smandapati/ndnSIM/ns-3/build'
Waf: Leaving directory `/home/smandapati/ndnSIM/ns-3/build'

During handling of the above exception, another exception occurred:
