.. note::
As of January 2022 (ns-3.36 release and later), the minimum g++ version is g++-8.
Older Ubuntu releases (18.04, 16.04) come with an older default g++. On Ubuntu 18.04, this
`StackOverflow answer <https://askubuntu.com/a/1028656>`_ can be followed to install and
prefer g++-8. On older Ubuntu such as 16.04, to use the most recent |ns3|, you must install
g++-8 or g++-9 from the `Ubuntu toolchain <https://launchpad.net/%7Eubuntu-toolchain-r/+archive/ubuntu/test>`_.
As of July 2023 (ns-3.39 release and later), the minimum g++ version is g++-9.
Older ns-3 releases may work with older versions of g++; check the RELEASE_NOTES.
