Chao Hai, well to the best of my knowledge, gdb should not have to knwo where to look for the files as it is launched on an executable. What is is used for is to know in which function the problem happens. Then you should know in which file you have implemented this function (else a grep command could help a lot ;o) ).
have you had a look at the line 531 of packet.h (probably located in folder /ns-allinone.../ns-version/common) ? Ho I almost forgot: i am french so if you wanna discuss this topic off-line in french, you may e-mail me.
