[ndnSIM] How to use hijacker in ndnSIM?

Alex,

Thanks for the quick reply. After I modify the wscript file to include
hijacker.cc , it works.

More questions in lines.

Now I try to use files "ndn-simple-with-custom-app.cc", "custom-app.h",
"custom-app.cc", "hijacker.cc", and "hijacker.h" in directory "scratch".
They work in the examples, so I think they should work in the scratch
directory.

In addition, I also add two lines to include custom-app.h and hijacker.h in
ndn-simple-with-custom-app.cc:
*#include "custom-app.h"*
*#include "hijacker.h"*
*
*
However, when I run the command "./waf
--run=scratch/ndn-simple-with-custom-app", it gives me a lot of
"relocation" error message:
