NS2 error 139
 

i'm trying to add a new protocol with the help of http://elmurod.net/?p=157. then i did make, but i get the following error

g++ -Wl,-export-dynamic -o common/ptypes2tcl common/ptypes2tcl.o
./common/ptypes2tcl > gen/ptypes.cc
/bin/sh: line 1: 19172 Segmentation fault ./common/ptypes2tcl > gen/ptypes.cc
make: *** [gen/ptypes.cc] Error 139

can u say me how to rectify this.

You're running a makefile that runs a script that's building programs to generate more programs...

... and somewhere in all of this, the executable "./common/ptypes2tcl" is dumping core.

You need to debug ptypes2tcl to find the problem.

Or ask the author, or somebody in a relevant mail group or IRC channel.

thank u sir, i've corrected the errors but i'm getting errors while i run the trace file, the errors are like the changes i've done in files have not updated.

Hi sir
My name's is nawel kortas , i'm from tunisia

thank you very much

# 4 .
You are using the wrong compiler. Should be g++-4.1, not g++.
Please read http://www.linuxquestions.org/questi...-4175451154/#6
> Post #6 : That's the answer you got a month ago.
And there is an unanswered question in that post #6 :
"Where did you get the information that the above will work ?"
I.e. you are trying to mix two patches, ns-229-nist-mob + pmip6-for-ns-229.
? The two patches may conflict ?

Thank you sir for your replay
I still have the error

Ns make failed!


Do have another solution
thank you

# 6 .

Well, then please tell what you are doing.
The error tells very little when all the beginning is mising.

Things to specify when you ask an ns2 question :
OS name, version, architecture. Like Ubuntu 10.04 - 32bits(i686).
Ns2 version. 'ns-allinone-2.29.3.tar.gz' ? ( If ns-2.29 : version 3 is a must.)
And if any changes were made to ns-2.xx : Please specify patch name(s).

i Use ubuntu 10.04 (32 bit) , I want to add wimax module to ns-allinone-2.29 from this link http://www.lrc.ic.unicamp.br/wimax_ns2/ (this is an old version but i want it to make comparison with my work )

i install my ns-allinone-2.29 correctly then i add the mac files , i change the makefile.in , i copy the modification in the packet.h and tcl/lib file then i try to make

so i get the last errors

# 8 .

You are right. "WiMAX_module-1.02.zip" does not work in ns-2.29.
Is for ns-2.28 :
1) tar xvf ns-allinone-2.28.tar.gz
2) patch -p0 < ns228-gcc40.patch
3) patch -p0 < ns-2.28-gcc410.patch <Enter> <Enter> <Enter>
4) cd ns-allinone-2.28/
5) tar xvf wimax102-ns228-patch.tar.bz2
6) export CC=gcc41 CXX=g++41 && ./install

'wimax102-ns228-patch.tar.bz2' is the repacked WiMAX_module-1.02.zip + Makefile.in.
Download link https://docs.google.com/file/d/0B7S2...it?usp=sharing

Note 1: You can have as many versions of ns-allinone as you want,
installed at the same time. But do not add any path text to .bashrc.

Note 2: I don't remember any wimax examples.tcl that actually work.
See http://www.linuxquestions.org/questions/tags/wimax/

Thank you very much , it's very sweet from you :)

I need you help again sir
when i configure then make the nam-1.11 folder i get those errors , do you have any idea about this


/usr/bin/ld: nam: hidden symbol `__stack_chk_fail_local' in /usr/lib/libc_nonshared.a(stack_chk_fail_local.oS) is referenced by DSO
/usr/bin/ld: final link failed: Nonrepresentable section on output
collect2: ld returned 1 exit status
make: *** [nam] Erreur 1

# 11 .

Nam is a separate application. Any nam can be used.

Suggest nam-1.14.i586.tar.gz
https://docs.google.com/uc?id=0B7S25...=CLPiyxo&hl=en
cd nam-1.14.i586/ && sudo cp nam /usr/local/bin/


? By the way : Why run './configure && make' in nam-1.11/ ?
Is handled by ./install.
And : There is no such thing as ./configure in any ns-2.28 application.
The command is $ export CC=gcc41 CXX=g++41 && ./configure .

Getting Out of segmentation Fault
 

Dear raji27,

Could you please help to solve the segmentation fault problem?

I am patching GPSR to NS-2.33 in Ubuntu-12.04

with thanks.

Post #13, @Chakraborty.

What is it you are trying to do ?
** Using "ptypes2tcl" :
$ cd ns-allinone-2.33/ns-2.33/common/ && ./ptypes2tcl

Two things are wrong. Do not use root for ns2 commands.
And : There are generally no debugging symbols in any ns2 executable.
Meaning you can't use gdb to debug those.

Then please do not ask off-topic questions in a WIMAX thread.
As you can see from post #5, you can get segmentation fault,
when you are using a wrong compiler.
