Installing ns-3.37 and ns-3.35 in Ubuntu | Ubuntu 22.04 | NS3

Multiple Versions of ns3 in Ubuntu 22.04

In this post, we are going to install two versions of ns3 namely ns-3.35 and ns-3.37 

My OS is : Ubuntu 22.04 LTS (Long Term Support)

ns-3.35 uses waf and (./waf --run scratch/first) 
ns-3.37 uses cmake  (./ns3 run scratch/first.cc)

So we will install both the packages 

Go through the video for complete instructions


To start with 

$ sudo apt update 
$ sudo apt install build-essential autoconf automake libxmu-dev g++ python3 python3-dev pkg-config sqlite3 cmake python3-setuptools git qtbase5-dev qtchooser qt5-qmake qtbase5-dev-tools gir1.2-goocanvas-2.0 python3-gi python3-gi-cairo python3-pygraphviz gir1.2-gtk-3.0 ipython3 openmpi-bin openmpi-common openmpi-doc libopenmpi-dev autoconf cvs bzr unrar gsl-bin libgsl-dev libgslcblas0 wireshark tcpdump sqlite sqlite3 libsqlite3-dev  libxml2 libxml2-dev libc6-dev libc6-dev-i386 libclang-dev llvm-dev automake python3-pip libxml2 libxml2-dev libboost-all-dev 

I have downloaded both the versions of ns3 from https://nsnam.org 

Copy both the softwares from the Downloads/ folder to the home folder (in my case its /home/pradeepkumar/)

Now extract both the versions using the GUI method.

Just right click and click "Extract Here"

We will install one by one, First let me try ns-3.37, In case of any errors, we need to correct it as well.

$ cd ns-allinone-3.37/
$ ./build.py --enable-examples --enable-tests
This process might take a longer time based on your RAM and Processor. I have an M.2 SSD and Intel i5 - 10th Gen processor with 16GB RAM. the installtion should be fast...

lets see...

ns-3.37 installed succesfully and we have tested an example as well. 

$ ./ns3 run hello-simulator 
$ ./ns3 run scratch/first.cc 
The output is shown below in the figure

ns3 example
ns3 example

Now we will install ns-3.35 

$ cd
$ cd ns-allinone-3.35/
$ ./build.py --enable-examples --enable-tests

In case, if you get the following error
pybindgen(ns3 module antenna)
Do this step
Go to the following URL
and make the changes as given in the video

We have installed two version of ns3.37 and ns-3.35 successfully in Ubuntu 22.04
