How to upgrade Ubuntu 16.04How to upgrade gcc-6 and GroupMill 6
This article will explain in detail how Ubuntu 16.04 upgrades gcc-6 and glossy music 6. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.
In the afternoon, use Matlab to compile a cpp program, prompting that the gcc-5 version is too low. In a fit of anger, upgrade gcc-6!
1. Add source
Sudo add-apt-repository ppa:ubuntu-toolchain-r/testsudo apt-get update
2. Install gcc-6 and glossy music 6
Sudo apt-get install gcc-6 gallop music 6
3. Configure gcc,g++ links
We look at the gcc currently used by the system and find that it is a symbolic link:
Ll / usr/bin/gcclrwxrwxrwx 1 root root 5 Nov 16 16:49 gcc- > gcc-5
Gmail + is also:
Ll / usr/bin/g++lrwxrwxrwx 1 root root 5 Nov 16 16:49 grubbing-> glittering murmur5
So we can redirect the gcc link to gcc-6:
Cd / usr/binsudo sudo rm gccsudo ln-s gcc-6 gcc
Similarly, grub + is re-linked to glossy colors 6:
Sudo rm g++sudo ln-s glossy music music 6 galleys +
Re-check the links for gcc and Gmail +:
Ll / usr/bin/gcclrwxrwxrwx 1 root root 5 Nov 16 16:49 gcc- > gcc-6
Ll / usr/bin/g++lrwxrwxrwx 1 root root 5 Nov 16 16:49 grubbing-> glittering murmur6
By the way, take a look at the versions of gcc and Gmail +:
