thank you for your response,
yes i tried with manual and wiki of ns3.
Firstly i have downloaded ns3 allinone version 3.12.1 and cygwin. Then i install cygwin. I put ns3 allinone in usr/local. Then i tried with the command ./build.py it says "/usr/bin/env: python: No such file or directory" but there is build.py in that folder. So i am wondering if i need to install python first or it is already there.
If you know something can you please guide me few steps for starting...
Also which linux emulation is good for ns3 in windows platform? like cygwin, MingGW, Eclipse and other if any?
I would be grateful if you guide some steps.\
Thank you in advance.
