visualizer usage

[Janki Chhatbar]

HI

I have added obj = bld.add_ns3_program('visualizer') in ns3-20/examples/tutorial/wscript and ran first.cc in ns3-20 folder by giving command ./waf --run first --visualize. I have not included visualizer-module.h in first.cc but have included ns3::Visualizer::Run();.

This is throwing error  obj = bld.add_ns3_program('visualizer')
AttributeError: 'BuildContext' object has no attribute 'add_ns3_program'
 
Can anyone help..

Hi,

mind if I ask you where did you find the idea to add "obj = bld.add_ns3_program('visualizer')" to the wscript ?

That post is from 3 years ago, and it refers to **10** versions ago. It's not a big surprise if it's not working.

Check the PyViz wiki page: http://www.nsnam.org/wiki/PyViz, read it, understand it, and you'll find out how to enable the visualiser in the tutorial.

Note that the wiki page is old as well, and the script syntax is slightly changed. However, if you understand what's the idea, then you'll know what to do.

Got it... Add
CommandLine cmd;
cmd.Parse (argc, argv);

in the code and run the code with --vis option.
