 Instructions for Installing Ns2.34 in Ubuntu versions

Instructions for Installing Ns2.34 in Ubuntu 10.04

This manual will work for NS2 allinone-2.34 with Ubuntu 10.04. As Ubuntu is a new version 10.04 need following packages before any further installation, otherwise it will not work with it.

Please follow the following steps:

1.   Install necessary tools for building:

         sudo apt-get install build-essential autoconf automake libxmu-dev   gcc-4.3

2.   It turns out that otcl does not like the version of gcc installed by default in Lucid. So go ahead and change ns-allinone-2.34/otcl-1.13/Makefile.in

Find the Line That says
CC = @CC@

                                        and change it to:

CC = gcc-4.3

3.   Now follow the following steps for installation of nsallinone 2.34 and it will work with your machine. (Copy ns-allinone-2.34.tar.gz)

Suppose that there is "ns-allinone-2.33.tar.gz" in current directory (e.g. "~/" for me is "/home/ram").

All steps are done in Terminal, so open a terminal in Accessories/Terminal.

To extract the file:

tar xvfz ./ns-allinone-2.33.tar.gz

4. Change your directory within terminal as following way

$ cd /home/ram

     $ cd /home/ram/ns-allinone-2.34

4.   Download & install some packages from repository if needed

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

5.   Install the ns2

$ cd ns-allinone-2.34

$ ./install

    

    6. Edit some paths

         $ gedit ~/.bashrc

Put these lines on that file in the last. Off course, you might change

/home/ram for it depends on where you extract ns-allinone-2.34.tar.

# LD_LIBRARY_PATH
OTCL_LIB=/home/ram/ns-allinone-2.34/otcl-1.13
NS2_LIB=/home/ram/ns-allinone-2.34/lib
X11_LIB=/usr/X11R6/lib
USR_LOCAL_LIB=/usr/local/lib
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$OTCL_LIB:$NS2_LIB
:$X11_LIB:$USR_LOCAL_LIB

# TCL_LIBRARY

TCL_LIB=/home/ram/ns-allinone-2.34/tcl8.4.18/library

USR_LIB=/usr/lib

export TCL_LIBRARY=$TCL_LIB:$USR_LIB

# PATH
XGRAPH=/home/ram/ns-allinone-2.34/bin:/home/ram/ns-allinone-
2.34/tcl8.4.18/unix:/home/ram/ns-allinone-2.34/tk8.4.18/unix:/home/ram/ns-
allinone-2.34/xgraph-12.1/
NS=/home/ram/ns-allinone-2.34/ns-2.34/
NAM=/home/ram/ns-allinone-2.34/nam-1.13/
export PATH=$PATH:$XGRAPH:$NS:$NAM

7.   Validate it (take very long time compare to install process)

$ cd ns-2.33

         $ ./validate

If you have any doubts please comment.. i will try to solve it my level best. Thank you.

Testing ns2 Installation

Use the following ns batch command

set ns [new Simulator]
$ns at 1 “puts \“Hello World!\””
$ns at 1.5 “exit”
$ns run

Then,

1. Copy the commands above and paste in the text editor
2. Save the file as simple.tcl
3. Type command in command prompt

$ ns simple.tcl

4. It will show Hello World in the line below
TroubleShooting

1. Problem : The system cannot find Tcl or it tells that Tcl does not install correctly

Solution 1 : Check your ns tcl nam ... version, check folder name. If it is not correct, edit the .bashrcSolution 2 : run ./install again

2. Problem : nam does not work

Solution 1 : In fact, you need to change that particular file in your Linux manually.

Here is what you should do.

Apply the following patch :

--- tk8.4.18-orig/generic/tkBind.c 2006-07-21 08:26:54.000000000 +0200
+++ tk8.4.18/generic/tkBind.c 2008-07-05 12:17:10.000000000 +0200

Create a file with the above lines and name it : abc.patch. To apply the patch navigate to ns directory and execute the following command in terminal:

patch -b < abc.patch

Then run $ ./install to compile and install ns2 again. Hope this helps, drop in your comment for HELP ! :)
