When will GCC be updated in 16.04 and 18.04?

Question

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?

Answer 1

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.
