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/)
My Website is https://www.nsnam.com
My Github is https://github.com/tspradeepkumar

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 |
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
