I had code that worked fine. I shut down my PC (Ubuntu) and then, built the same software (ns-3) and now I get the error:
Traceback (most recent call last):

EOFError
I am just amazed at this, how could 2 minutes before everything was fine and now I am screwed by this error.
What should I do, I am totally bewildered. I have a deadline and suddenly this code stops, it worked fine, only change I did was to switch off my PC.
NS-3.6 is a very very old ns-3 release which you are trying to build with a new system (gcc compiler, python etc). I think the only solution to solve the problem is to update the simulator to a new release.
Try to rebuild it. First write: rm -rf build and build from scratch
