[ndnSIM] ndnSIM Digest, Vol 24, Issue 6

[ioannoa]

Hello all,

I am trying to implement a forwarding protocol but I fell into a few 
compilation errors, i.e.

In my simulation file I include the below:

#include "ns3/ndnSIM/model/fib/ndn-tfib.h"
#include "ns3/ndnSIM/model/conx/ndn-conx.h"

where conx is a new folder containing the ndn-conx.h and ndn-conx.cc 
files. Furthemore, in my StackHelper (.h & .cc) files I have included 
both headers and defined the corresponding functions for the 
installation on a node similar to pit, fib etc. Could, please someone 
point me out what my error may be? My simulation runs fine on my laptop 
(MAC OS X 10.8) but fails when I try it on Ubuntu 12.04.

Also, I get some mistakes if I do not disable python.

_wrap_PyNs3NdnPitEntry__tp_init__1(PyNs3NdnPitEntry*, PyObject*,

Waf: Leaving directory `/home/ioannoa/ndnSIM/ns-3/build'


The reason is that I have inserted a new bool field in a pitEntry that 
specifies whether my entry corresponds to a fib entry or to a tfib 
entry, (i.e. tfib table holds temporal entries for forwarding).Is 
modulegen__gcc_LP64.py the corresponding python file that I should 
change in order to make this work as well?

Many thanks,
Andriana.
