I'd like to get the latest releases of g++ (and clang) via package manager (apt). Currently I need to compile gcc/g++ on my own which needs really a lot of time.

Are there any repositories with "special packages" like g++-10-2, g++-11 or just g++-master?

I'd be really nice :-)

    Does this answer your question? [Why don't the Ubuntu repositories have the latest versions of software?](https://askubuntu.com/questions/151283/why-dont-the-ubuntu-repositories-have-the-latest-versions-of-software) – N0rbert Jul 24 '20 at 17:13

    Thanks for your answer. In general it is a good way to go. But because I'm developer who uses C++20 features I'd like to get latest releases (for my dev). For me it would be okay to add "beta" or "dev" repositories (called PPA). I know such software can contain new not fixed bugs... – Bernd Jul 24 '20 at 17:21
  • I did already: sudo add-apt-repository ppa:ubuntu-toolchain-r/test – Bernd Jul 24 '20 at 17:21
  • I would like to get a "developers' PPA" or "Ubuntu+1 repositories" – Bernd Jul 24 '20 at 17:34
  • Actually these Linux systems are in virtual environment and used only to compile C++ - so I don't care about system stability or whatever... – Bernd Jul 24 '20 at 17:41

    The "dev" release of Ubuntu is currently 20.10, not 20.04. It will be released in October 2020. 20.04 has no "dev" repositories since it's already released. – user535733 Jul 24 '20 at 17:43
  • Is it possible to update ubuntu to version 20.10 (I use WSL - which has only 20.04)? In the answeres linked by N0rbert I found some nice tool "Homebrew", I'll check it... – Bernd Jul 24 '20 at 17:54
  • It seems to have only old versions too... – Bernd Jul 24 '20 at 18:03

There seems to be no way to get up-to-date packages for ubuntu, you have to built them by yourself...

There is a solution via ppa.

You can find the instructions here: Install g++ 11 on Ubuntu 20.04
