Please edit post # 1 to use code tags :
Type [/code] at text end, and [code] at start.
http://www.linuxquestions.org/questi....php?do=bbcode

And you will have to attach the tcl script : As name.tcl.txt please.
Attachments : The paper clip tool in the 'Adcanced Editor'.

Editing post # 1 to code tags : Use the 'Edit' button !

And please delete the quoted text in post # 3. No reason for repeating.

The two usual pieces of information are missing :
OS Name : $ cat /etc/*release* <Enter>
Architecture : $ uname -m <Enter>

And last : Which version of gcc/g++ was used to compile ns-allinone-2.35 ?

Please remove the "Backtrace" text from posts #1 and #3.

You have some difficulties finding that 'Edit' button, haven't you ?

And please read my edited post #4.

i use the linux mint version of linux with oracle virtual machin
this is the informations of my system
name : i686
DISTRIB_ID=LinuxMint
DISTRIB_RELEASE=12
DISTRIB_CODENAME=lisa
DISTRIB_DESCRIPTION="Linux Mint 12 Lisa"

But the version of GCC i think that is 1.4
Please tell me haw can i avoide this message and why did i get it . :
juste an indication i have simulated the same tcl script but i have changed it to simulate tcp wireless and i did'nt have this message it runs well i have this message only while executing tfrc wireless

knudfl · 05-03-2013, 08:06 AM

# 7. Mint 12 : That's basically Ubuntu 11.10 .

The default compilers for Mint 12 are g++-4.4, g++-4.5, g++-4.6.
If you do nothing to choose a compiler, gcc/g++ -4.6 will be used.

Installing ns-allinone-2.35 :
1) cd ns-allinone-2.35/
2) export CC=gcc-4.4 CXX=g++-4.4 && ./install
3) cd ns-2.35/
4) cp ns ns235-orig : Then you have a backup with no patches.
5) sudo cp ns235-orig /usr/local/bin/
... Then you can type $ ns235-orig dccp-wireless.tcl : EDIT :
EDIT, sorry, this one : $ ns235-orig tfrc-wireless.tcl

ines8989 · 05-03-2013, 08:12 AM

Thanks a lot for your reply .

But i want to execute tfrc-wireless.tcl the code that i have sent for you not dccp-wireless.tcl .
i must write this steps before taping ns tfrc-wireless.tcl ?

knudfl · 05-03-2013, 11:18 AM

# 9 .

Sorry, got things mixed up .

No issues here with $ ns tfrc-wireless.tcl
... where "ns" means any properly built ns from ns-2.34 or ns-2.35 .
And $ nam wafa.nam : OK too.

Did you use any patches for ns-2.35 ? ?

What is the text in ns-2.35/Makefile, line 37 ?
Should be : CPP = g++-4.4

And what did you do to change the error from "buffer overflow .."
to "stack smashing .." ? ?

ines8989 · 05-04-2013, 06:30 AM

I would thank you a lot mr knudfl for your reply . I didn't use any patche for ns2.35 i juste installed it successfully.

And the message of stack smaching appears only when i execute the file tfrc-wireless.tcl i executed the same script juste i changed the agents for tcp to simulate tcp-wireless and it works well.

Before reinstalling ns2.35 i had the message buffer overflow . But after reinstalling ns2.35 successfully i have the message
stack smashing with the tfrc-wireless file .
I have seen in my makefile there is : CPP = g++

I have seen in my makefile there is : CPP = g++

OK.
Then better set up another ns-allinone-2.35 to try achieving a better result.
You can have as many versions of ns-allinone-2.xx as you want,
installed at the same time. But do not add any PATH text to .bashrc.
Not required. The executable 'ns' will know the location of it's libraries.
Example, having multiple ns2 :
/home/name/a/ns-allinone-2.35/
/home/name/b/ns-allinone-2.35/
/home/name/c/ns-allinone-2.35/
/home/name/a/ns-allinone-2.33/
/home/name/a/ns-allinone-2.34/
/home/name/b/ns-allinone-2.34/

And how to keep track of "40" different ns2 ? Very simple :
Just use different names for the executable ns : ns235-1 ns235-2 ns234, etc.
Your file "tfrc-wireless file" was executed OK here yesterday with :
1) $ ns235 tfrc-wireless file 2) $ ns234 tfrc-wireless
3) $ ns234-tora tfrc-wireless
.... ( I have about 50 different 'ns', renamed to <other-name>.)

The correct way of installing ns-allinone-2.35 :
export CC=gcc-4.4 CXX=g++-4.4 && ./install

Thank you a lot for you help . I didn't find in the net other nsé.35.tar.gz file to install other then in the site
www.sourceforge.net

Have you please any other source to download from it ns2.35 or i suggest you me to try with the ns2.34 ?
wihile installing ns2.35 i have swited this steps :
sudo apt-get update

sudo apt-get install build-essential autoconf automake libxmu-dev

tar zxvf ns-allinone-2.35.tar.gz
cd ns-allinone-2.35

./install
are they true ? should i juste add export CC=gcc-4.4 CXX=g++-4.4 && ./install better than /install ?
Thanks for you

Yes, the correct install for ns-2.35 / Ubuntu 11.10 .. 13.04 is :
export CC=gcc-4.4 CXX=g++-4.4 && ./install

You will of course have to install the "4.4 compilers" beforehand :
sudo apt-get install g++-4.4
