[ndnSIM] declaring a variable in ndn-forwarding-strategy

[Alex Afanasyev]

Hi Isuru,

Are you running simulation in the visualizer?  Try to run without it and in debug mode (in case you have compiled with ./waf configure -d optimized, re-compile with ./waf configure -d debug or just ./waf configure).

The variable declaration seems right.  The problem that I could think of is that you're trying to use it in application's constructor, when neither Node() nor strategy objects are not yet set.

Btw. What the effect you're trying to achieve?  Normally (in "real world") applications cannot directly communicate with the forwarding daemon.  Or is it something that is simulation-specific?
