I think you should install gdb debugger. It can show you complete trace of the possible effective place. Wherever I have any segmentation fault I like to use debugger ($gdb ns; run test.tcl <enter> )that give you an option of $bt, so that you can see at which point in execution this error occurs. It makes easier for the programmer to rectify the problem.

I also modified the some default paths to explicit paths. I'm using Ubuntu 10.04LTS, and ns-2.33 Pls share with me your experience on this ?

You try to trace from all those changes you made. Possibility is you are pointing to something which is not existing at the time of execution. ________________________________ From: mai ragaei mailto:mairagae...@hotmail.com To: ns-users@ISI.EDU Sent: Friday, 1 March 2013 11:08 AM Subject: [ns] Segmentation fault problem Hi, I used ns2.34 with nsmiracle , I modified code in nsmiracle and when I run an example, it produce an error : segmentation fault Please can any one tell me the reason to produce segmentation fault ?
