The current version of supported GCC on Ubuntu 16.04.3 LTS is 5.4 version and the latest GCC version is already at 7.0. So can we expect a newer version of GCC in Ubuntu 18.04 LTS?

You can already install gcc 7.0 in Ubuntu 17.10 from the default repositories. The latest version of GNU C compiler in the Ubuntu 17.10 and 18.04 default repositories is gcc-7. To install gcc-7 in Ubuntu 17.10, 18.04 and 18.10 open the terminal and type:

sudo apt install gcc-7 

To install gcc-8 in Ubuntu 18.04 and later open the terminal and type:

sudo apt install gcc-8

To install gcc-9 in Ubuntu 19.04 and later open the terminal and type:

sudo apt install gcc-9

You can install gcc-7 in Ubuntu 16.04 from ppa:jonathonf/gcc-7.1.

sudo add-apt-repository ppa:jonathonf/gcc-7.1  
sudo apt update  
sudo apt install gcc-7  

You can install gcc-8 in Ubuntu 16.04 from ppa:jonathonf/gcc-8.0.

sudo add-apt-repository ppa:jonathonf/gcc-8.0  
sudo apt update  
sudo apt install gcc-8 

It makes more sense to either wait until April and install gcc-7 in Ubuntu 18.04 or else install it in Ubuntu 17.10 now.

  • GCC 8.1 was released today. No idea when it will appear in a repository. But you can always download and build it. Loading up Ubuntu 18.04 and compiling gcc 8.1 would feel like hanging ten on the hood of Elon Musk's spacefaring Tesla Roadster... – Blair Houghton May 2 '18 at 16:50
  • @BlairHoughton gcc-8 has landed in the official Ubuntu repositories for Ubuntu 18.04 and later. To install gcc-8 in Ubuntu 18.04 and later run this command sudo apt install gcc-8 – karel May 2 '18 at 21:40
