Use GCC11 on (K)ubuntu 20.04

Question

I want to use some new C ++ 20 functions that are implemented in the as-yet-unreleased GCC-11. I tried installing the package on Ubuntu 20.04 but as expected it doesn't exist yet. The web search didn't come up with anything useful either.

Is there any way to use GCC-11 on Ubuntu 20.04?

@KamilCuk Never done this before. Is there a guide somewhere? — Silicomancer, Apr 26 '21 at 20:47
I also like doing it like so: take the package _build sources_ for older version ex. https://packages.ubuntu.com/focal/gcc-10 , bump up the version in build files and source location there and build the package. It's sometimes much easier to do because it already tracks build dependencies and builds a ready-to-use package that is easy to uninstall. — KamilCuk, Apr 26 '21 at 21:24

From the page linked, the PPA in question: `sudo add-apt-repository -y ppa:ubuntu-toolchain-r/test` – Dumaiu Sep 09 '22 at 00:51
