Uninstalling gcc

Question

I want to uninstall my gcc by terminal. When I type

gcc --version

The output is

gcc (Ubuntu 5.4.0-6ubuntu1~16.04.4) 5.4.0 20160609
Copyright (C) 2015 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO

Could anyone help me? How can I install the last version of gcc after that?

This question is not about C++, so don't tag C++. – Baum mit Augen Oct 11 '17 at 11:43 — Baum mit Augen, Oct 11 '17 at 11:43

Use the following command (Replace <version> with the appropriate version):

sudo apt-get --purge remove gcc-<version>

You can install a specific version of a program using apt, you can use the following command. (Replace <version> with the appropriate version)

sudo apt-get install gcc=<version>

Alternatively, you can use Synaptic Package Manager.

sudo apt-get update
sudo apt-get install synaptic

Note that, you might need GCC for some programs. If you face any driver issues while installing programs / drivers you can install the latest GCC by using:

sudo apt-get install gcc

You can use synaptic package manager. I've updated the answer. – Lakshmikant Deshpande Oct 11 '17 at 11:53
@LakshmikantDeshpande why do you say it's dangerous to uninstall GCC in Ubuntu? The only problem I can see is if you have drivers that require on DKMS. – giusti Oct 11 '17 at 12:08
That's why I was suggesting that it is a dangerous command. (nvidia drivers in my case). Thanks :) – Lakshmikant Deshpande Oct 12 '17 at 09:46
