[ns] segmentation fault (core dumped)
I did some changes in the LAR protocol and suppose the new protocol is named as ABC . When i am doing make clean and then make. object file ABC.o was successfully created. Then i tried to run tcl file , nothing has been written in the trace file and it gave me the following error 21052015$ ns234 new.tcl scen1 setting other default settings... removing unecessary packet headers... num_nodes is set 100 INITIALIZE THE LIST xListHead loading mobility file loading traffic file Starting Simulation... Segmentation fault (core dumped) I tried a lot but unable to find out where is the error. I am unable to find out where is the error . in .cc file or in .tcl file. could someone please help me. My work has been stucked and i searched a lot but didn't get anything. please please .. help me . Any hints -- how to proceed further ... thanks a lot
Re: [ns] Segmentation fault (core dumped) error with NAM command in GPSR Keliu wireless-gpsr.tcl example
Hi . I guess the GPSR-KeLiu protocol isn't really supporting nam ? There is a text file TextFile-modify-wireless-gpsr about nam in the examples. But I don't remember that anybody ever succeeded with a GPSR-KeLiu nam file.

[ns] Segmentation fault (core dumped) problem in ns2 crcn tcl script
While compiling crcn tcl script the following error exisits Segmentation fault (core dumped) Consequences: Trace file is not completed which leads to incomplete nam file. Simulation time 50 sec and traffic connections end at 45 sec while trace file stopped at 0.003 sec. I tried to change AODV to DSR where it stopped at 7 sec. Please provide me with solution to this.

[ns] segmentation fault core dumped in ns2-2.27 when I revise the variable of next hop
hi,everyone today I revise a little in one routing protocol, before I revised ,the source code linkes follow: ch-next_hop_ = -1; //Broadcast address which means next hop is broadcast address,I want to indicate the next hop,for example,the topology likes this node 0 - node 1 — node 2 ,so node 0's next hop is node 1 so I revise the code linkes this if(index_==0) ch-next_hop_ = 1 else (index_==1) ch-nedxt_hop_=2 I do this in order to fix the next hop,however,I recompile the ns2,everything goes ok, but I use the same script to do the experimental, the screen display : segementation fault (core dumped) I check related website,and get the information that I may visit the memory I did not declared, I think may be I use the node address as the ip address! could any body tell me why ? so Urgent!

[ns] Segmentation fault (core dumped) for ping example
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: - $ ns link.tcl warning: no class variable Agent/Link::packetSize_ see tcl-object.tcl in tclcl for info about this warning. warning: no class variable Agent/Link::off_link_ warning: no class variable Agent/Link::packetSize_ see tcl-object.tcl in tclcl for info about this warning. warning: no class variable Agent/Link::off_link_ Segmentation fault (core dumped) --- -- Regards, Manoop Talasila
Re: [ns] segmentation fault (core dumped) using ZRP in ns-2.27
HI Batbold Toiruul,
here is no the solution to *segmentation* *fault*s. From what I've seen on
this list and
in practice, there can be several causes:
1. you deleted a resource from within TCL, causing pointers in C++ to point
to
memory regions no longer in use. Fix: be careful what you delete in TCL.
2. you added or modified the ns2 source code:
a. there is a dependency problem and parts of your source have not been
recompiled. fix: type make clean and make to make ultimately
sure
that all code is within sync with each other
b. your additions are the cause of the memory violation. fix: fix!
how to find the location of your error?
a. first you have to convince your shell to produce a coredump when a
*segmentation* *fault* occurs. Usually this is done with the command
ulimit -c 10 which sets the limit of coredumps to really huge
so that they are allways produced.
b. add -g to the CFLAGS in the Makefile (and Makefile.in to make sure
your change is not removed when you ./configure ns2). This flag says
that
debugging code is compiled into the executable.
c. make clean make to have the debugging code properly compiled in.
When a *segmentation* *fault* occurs, type: gdb -c core, then in gdb tell
it that you want to load symbols from the ns executable with file ns,
and then you can inspect the stack (bt), select a stack frame (select 0)
and inspect the values of variables in that stack frame. Use the online
help of gdb to get familiar with it.
This link may be useful to you.

+fault
Good luck debugging!
3. May be you are accessing the wrong memory location while declaring your
data structures like linked list, arrays etc

The fault occured due to a part of code making invalid access to memory ( obviously ! ) but inorder to know which part of the code.. pl install gdb in ns.. so that when you run 'x.tcl' you will be able to get loads of info which might help you to spot which part of code leads to seg fault.

I have 69 nodes, it was working well until yesterday that I added one line to create a new variable. After the value set up the simulation crash around the middle, if I remove the line, it works well.

Re: [ns] Segmentation fault (core dumped)
Please check your tcl script, if you are using DSR routing protocol you must set the interface queue type with CMUPriQueue. Instead of, set opt(ifq)Queue/DropTail/PriQueue; use: set opt(ifq)CMUPriQueue; Hope this helps!

[ns] segmentation fault(core dumped)
Hi,
I have downloaded and setup ns-allinone-2.26 with cygwin and made some
changes to run Ping Agent as it was described at HYPERLINK
http://www.isi.edu/nsnam/ns/tutorial/http://www.isi.edu/nsnam/ns/tutorial/
I can run the example script in the website. Also I can run other scripts I
wrote.
Then I tried to write a script and it became a very big problem for me.
When I try to run it says segmentation fault(core dumped) and I could not
solve the problem.
I hope somebody can help me :)
Thanks for your time and attention
Sincerely ...

Re: [ns] segmentation fault(core dumped)
This problem has been addressed many times in this list. See
http://mailman.isi.edu/pipermail/ns-users/2003-August/034824.html for solution.
You can not use DSR and Queue/DropTail/PriQueue at the same time instead
use CMUPriQueue as ifqType.

[ns] segmentation fault(core dumped)
i have made a simple wireless ad hoc networks with 50 nodes,1000s simulation time..but there is a fault not allowed to run the program for 1000s and program is terminated with a fault known as segmentation fault(core dumped)..please any one can help me.. yas..
Re: [ns] segmentation fault(core dumped)
Hello Yaser, I think you have run out of memory. Try save some by disabling some trace options from your trace file( you can do that from your tcl script). Another suggestion would be to disable some packet headers Look for this at chapter 12 in the ns-2 manual as ns includes all packets headers of all protocols in every packet by default. This a lot of overhead. Another idea also would be to use also hierarchical routing ( look in chapter 29).This is a way to reduce memory requirements for your simulation. Hope the above will help you! regards, Michael Yaser Mahmood [EMAIL PROTECTED] έγραψε: i have made a simple wireless ad hoc networks with 50 nodes,1000s simulation time..but there is a fault not allowed to run the program for 1000s and program is terminated with a fault known as segmentation fault(core dumped)..please any one can help me.. yas.. - Χρησιμοποιείτε Yahoo!
