Hello,
I am assuming you are using a *nix system
It is some times simpler if you can locate the root cause of the
segmentation fault.
To do this, make the following changes to the Makefile in the
*/ns*-allinone/ns*/ folder.
1. locate the compiler command it will either be "cc" or "gcc". change
it to "cc -g" or "gcc -g". This will make the compiler generated flags
for gdb
2. Then type
>make clean
>make
this will re compile ns
3. then run ns using gdb using the command below
>gdb ns
>[inside gdb]r your-tcl-file.tcl
4. Then, when you get a seg fault, it will show you the line number
and file name which caused the Seg Fault. This will give you lot of
info to debug your code.
Hope that helped.
