Hi, I am a new user for Ns and i have a same problem like [EMAIL PROTECTED] I well studied document "Implementing a new MANET protocol in ns-2". I wrote the same code in ns-2. that was compiled without error. I made all indicated changes in ns-2 . After wich i recompile ns-2 by typing make at ns-2.29 directory it got compiled well. But when i try to use this protocol in my simulation script, it produces the following errors.

Please help me if you have already an idea of the reason of this problem Thanks in adavance. --------------------------------- Découvrez une nouvelle façon d'obtenir des réponses à toutes vos questions !
