How to install gcc-4.8 in Ubuntu 12.04 from the terminal

view story

http://askubuntu.com – I checked the gcc version on my system, its 4.6.3. I read that gcc-4.8 is out. I tried doing: sudo apt-get install gcc (gcc is already the newest version) sudo apt-get install gcc-4.8 (unable to locate package) Does anyone know how to? (HowTos)
