NS-2.35 installation in Ubuntu 22.04

This post shows how to install ns-2.35 in Ubuntu 22.04 Operating System

Since ns-2.35 is too old, it needs the following packages

gcc-4.8

g++-4.8

gawk

and some more libraries

Follow the video for more instructions

So, here are the steps to install this software:

To download and extract the ns2 software

Download the software from the following link

http://sourceforge.net/projects/nsnam/files/allinone/ns-allinone-2.35/ns-allinone-2.35.tar.gz/download

Extract it to home folder and in my case its /home/pradeepkumar (I recommend to install it under your home folder)

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

or Right click over the file and click extract here and select the home folder.

$ sudo apt update

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

To install gcc-4.8 and g++-4.8

$ sudo gedit /etc/apt/sources.list make an entry in the above file

deb http://in.archive.ubuntu.com/ubuntu/ bionic main universe $ sudo apt update

Since, it's ubuntu 22.04, you may get an error called GPG Error with a code like this "3B4FE6ACC0B21F32"

In case you get the GPG error, include the following command

$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 3B4FE6ACC0B21F32 $ sudo apt update $ sudo apt install gcc-4.8 g++-4.8 Make the changes in the following files

@CC@ to be replaced with gcc-4.8 @CPP@ to be replaced with g++-4.8 ns-allinone-2.35/Makefile.in /home/pradeepkumar/ns-allinone-2.35/otcl-1.14/Makefile.in nam-1.15/Makefile.in xgraph-12.2/Makefile.in In all the above places, change @CC@ to gcc-4.8 and @CPP@ @CXX@ to g++-4.8 Open the file ns-2.35/linkstate/ls.h in line number 137, change the line erase to this-erase Once the installation is over, Set the PATH and LD_LIBRARY_PATH information in the file located at /home/pradeepkumar/.bashrc export PATH=$PATH:/home/pradeepkumar/ns-allinone-2.35/bin:/home/pradeepkumar/ns-allinone-2.35/tcl8.5.10/unix:/home/pradeepkumar/ns-allinone-2.35/tk8.5.10/unix export LD_LIBRARY_PATH=/home/pradeepkumar/ns-allinone-2.35/otcl-1.14:/home/pradeepkumar/ns-allinone-2.35/lib

You can change /home/pradeepkumar to your home folder name.
