August 30, 2016 NetAnim is a GUI for ns3 (like visualizer). The last version 3.107 comes with ns3-allinone-3.25. To compile it follow these commands:

#Install required software
sudo apt-get install mercurial qt4-dev-tools

#Download netanim from mercurial
hg clone http://code.nsnam.org/netanim

#or use it from ns3-allinone-3.25
cd netanim-3.107

make clean
qmake NetAnim.pro  (For MAC Users: qmake -spec macx-g++ NetAnim.pro)
make 

./NetAnim

To generate an xml file compatible with netanim, you must add the following lines to your simulation file.

// netanim headers
  #include "ns3/netanim-module.h"

// file's name to run on netanim
  std::string animFile = "example.xml" ; 

  AnimationInterface anim (animFile);

// background image. Starts on 0,0, the image is not resized (scale 1,1) and the image has no transparency (alpha channel is one).
  anim.SetBackgroundImage("potential_google_fiber_cities.png",0,0,1,1,1);

// Set position of node 0 in the layout
  anim.SetConstantPosition(nodes.Get(0),115,63);
// Set description of node 0
  anim.UpdateNodeDescription (0, "Portland");
// Set size of node 0
  anim.UpdateNodeSize (0,10, 10);
// Set color of node 0 (R,G,B). In this case, color is blue.
  anim.UpdateNodeColor (0, 0, 0, 255);

  anim.SetConstantPosition(nodes.Get(1),83,219);
  anim.UpdateNodeDescription (1, "San Jose");
  anim.UpdateNodeSize (1, 10, 10);
// Set color of node 1 (R,G,B). In this case, color is green.
  anim.UpdateNodeColor (1, 0, 255, 0);

  anim.SetConstantPosition(nodes.Get(2),249,178);
  anim.UpdateNodeDescription (4, "Salt Lake City");
  anim.UpdateNodeSize (2, 10, 10);
// Set color of node 2 (R,G,B). In this case, color is red.
  anim.UpdateNodeColor (2, 255, 0, 0);

 

 

Maybe, when you'll execute your simulation you'll get this error:

undefined reference to `ns3::AnimationInterface::AnimationInterface(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >)'
undefined reference to `ns3::AnimationInterface::~AnimationInterface()'
collect2: error: ld returned 1 exit status

To solve it, you must Add 'netanim' to your wscript or move your simulation file to your scratch folder.
An extract of BRITE wscript as example:

obj = bld.create_ns3_program('brite-generic-example', ['netanim','brite', 'internet', 'point-to-point', 'nix-vector-routing', 'applications'])

   obj.source = 'brite-generic-example.cc'
