Hi NSusers,
I am new to ns2 and started learing from tutorial. I am using ns-2.34 in
windowsXP thru cygwin. In this version ping example for adding new protocol
comes with it with all settings already made in required files. So, I am
trying to add new protocol named "link" to ns2 using ns tutorial's
"ping" example steps.
I just renamed 'ping' with 'link' in the ping example files.
1. Copied link.cc, link.h files to folder "ns-2/apps/"
2. Defined LINK packet type in "ns-2/common/packet.h" as per the tutorial
ping example.
3. Defined default value of LINK agent in "ns-2/tcl/lib/ns-default.tcl"
as Agent/Link set packet_size 64
4. Defined new packet type in ns-packet.tcl
5. Added apps/link.o in Makefile
6. under ns2 directory i ran "make"
And finally, typed "$ns link.tcl" to run the example script, then i see
below error. I looked into archives and didnot find why this issue is coming
for the ping example.
Why do we see this error. "Segmentation fault (core dumped)" means what.
where can i see this stack trace atleat to find where it failed.
Please guide me in right direction to fix this.
I greatly appriciate your help.
Error from my cygwin window:
