Re: netanim problem _ wscript

[tina]

Hi all,

I am trying to use netanim in ns3-dce examples. i am trying to see animation of dce-iperf-mptcp" which is located in "~/dce/source/ns-3-dce/example". I added #include "ns3/netanim-module.h" and "AnimationInterface anim ("animation.xml");" before Simulator::Run(). but at the end i got the following error:

undefined reference to `ns3::AnimationInterface::AnimationInterface(std::string)'

In the manual and google group, I saw that I have to add the "netanim" module into wscript. So, i added  the following lines in the start of wscript which exists in "~/dce/source/ns-3-dce/" ( i attached the wscript to this email.) 

def build (bld) :

    obj = bld.create_ns3_program ('/home/user/dce/source/ns-3-dce/example/dce-iperf-mptcp', ['core', 'network', 'dce', 'point-to-point','netanim'])

   

 obj.source = '/home/user/dce/source/ns-3-dce/example/dce-iperf-mptcp.cc' 

Then i did "./waf build" but the following error i receive. 

Waf: The wscript in '/home/user/dce/source/ns-3-dce' is unreadable

IndentationError: unindent does not match any outer indentation level

Could you please guide me what i have to do?

I found the solution, funny! i had to add net anim in 

module.add_example(needed = ['core', 'network', 'dce', 'point-to-point', 'mobility','netanim'],

                       target='bin/dce-iperf-mptcp',

                       source=['example/dce-iperf-mptcp.cc'])

Hi, 

You could easily search for the error you are getting

"IndentationError: unindent does not match any outer indentation level"

and you could find several topics online with solutions, e.g.

http://stackoverflow.com/questions/492387/indentationerror-unindent-does-not-match-any-outer-indentation-level

Check the identation of your code, do not use tabs when spaces are required.
