[ndnSIM] ndnSim crash

[Spyridon (Spyros) Mastorakis]

Hi,

This error has to do with waf and not ndnSIM (assuming that you have not edited any wscripts). I would suggest you do the following:

1) Try to clean your current build by typing ./waf distclean and then configure and build again.
2) If 1 does not work, clone the ns3 and ndnSIM repos again and configure and build from scratch.
