Mobiwan and NS 2.34 ?

Augengrun · 03-19-2012, 01:58 PM

Hello,

Currently I am working on a project with NS2(version 2.34) and I have to use MIBV6.
I want to know if Mobiwan available for version 2.34 or not ?

Thank you,
S.K

Welcome to LQ. ..

..

The mobiwan patch is for ns-2.33, please see post #2 here
http://www.linuxquestions.org/questi...2-33-a-856104/

And : You can have as many versions of ns-allinone-2.xx as you want,
installed at the same time. But : Do not add any of them to a *PATH.

Thank you for your response
I installed ns2.33 and it works but when I add the mobiwan1 patch, the tcl programs do not work
The same problem in this post : http://www.linuxquestions.org/questi...obiwan-842269/

and I try to run this program in this post : http://www.linuxquestions.org/questi...2-33-a-843581/ and I have the same problem "Segmentation fault"

Does mobiwan depends on the version of ubuntu?

Ubuntu : 11.10

Thank you

The "post id" is missing. Please write e.g. #1, when it's about post #1.

2) http://www.linuxquestions.org/questi...2-33-a-843581/
Which post ?

Generally :
A default file.tcl is not supposed to work in a mobiwan patched ns2.
Only dedicated "mobiwan tcl files" must work.

The usual suggestion : Save the binary ns from an unpatched ns-2.33.
Also : copy the unpatched binary ns to /usr/local/bin/ as "ns233".
Other example (from today), post #2 here :

running nam with out.nam ...

... Which the expected OK result.

About your error ( Segmentation fault ) :
Probably the usual : Avoid Ubuntu 11.04, 11.10 ( 12.04 ) for ns2. Did all tests pass ?
If it must be Ubuntu : 10.04 should be preferred.
( All ns2 was made for and tested on CentOS / RHEL / Scientific Linux.)

P.S. : You could try out the old binary "ns233-mobiwan", that I am using.

I have the same problem. I will try with version 10.04 of ubuntu.
Thank you very much !

What do you mean ? ? The output shown on post # 7 is OK.

I do not know what I should do..

Two things : An OS for ns2 should be 32bits. ( i386 / i686.)
Not everything will work in a 64bits OS.
( The command 'uname -m' will reply with <arch>.)

And, most important :
ns-allinone-2.33 must be compiled with gcc-4.1 / g++-4.1
to get a usable result. ( sudo apt-get install g++-4.1 ).

.

Yes my os is 32 bits(i686)
"sudo apt-get install g++-4.1" not work (the same thing for gcc-4.1)

the default version that I found for gcc and g++ (gcc -v && g++ -v) is 4.6 and the minimum version that I can install with apt-get is 4.4
How I can return to the posterior versions (4.1 for example) if I use an ubuntu 11.10 ??

Augengrun · 03-27-2012, 04:06 PM

and the default gcc for ubuntu 10.04 is gcc-4.4..

knudfl · 03-27-2012, 04:08 PM

# 12 : No old Ubuntu compilers will work in Ubuntu 11.10.

I have patched up the Ubuntu 11.04 gcc41-compat,
so it will work in Ubuntu 11.10 :
sudo dpkg -i \
gcc41-compat-4.1.2.ubu1110_i386.deb g++41-compat-4.1.2_i386.deb
.. Then reboot, and the new gcc41 / g++41 will work.

Download gcc41-compat for Ubuntu 11.10 here ..
https://docs.google.com/open?id=0B7S...NjZmMHkyaE9Odw
g++41-compat https://docs.google.com/open?id=0B7S...FlODA4YWFiMTcx

Probably start from scratch with :
cd ns-allinone-2.33/ && export CC=gcc41 CXX=g++41 && ./install

Result, ns-2.33/validate :

Code:

validate overall report: all portable tests passed but
some non-portable tests failed:
     ./test-all-session

Ubuntu 10.04 isn't a problem. You can just do :
sudo apt-get install g++-4.1
