Ubuntu 13.04 with gcc/g++/gfortran 4.8 by default?

Solution 1:

Yes, Raring has gcc 4.7.3 by default. However you can install gcc 4.8 from Ubuntu toolchain PPA.

You can even install latest gcc snapshot by installing gcc-snapshot package available in universe repository. (not recommended though)

The following should do the trick:

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install g++-4.8

Note, if you receive an error saying that add-apt-repository does not exist, you can install it via:

sudo apt-get install software-properties-common
