Hello everybody, you can reduce the make time of NS2 from few minutes to
few seconds. In my case it is from 1.5 minutes to less than 5 seconds. What
I did is, I used Eclipse for NS2 (You can use this link
<http://durgeshkshirsagar.blogspot.in/2012/06/how-to-set-eclipse-for-ns-2-234-in.html>for
instructions.) and I just make it without cleaning it. The nice thing is it
will make only the modified files. As per my own experience I did't find
any bug in this method. Give it a try and use if it suites you. All the
best.
