Ever needed gcc/g++ 4.8 on your wheezy? Then do
sudo nano /etc/apt/sources.list
Change content to
deb http://mirrordirector.raspbian.org/raspbian/ wheezy main contrib non-free rpi deb http://archive.raspbian.org/raspbian wheezy main contrib non-free rpi # Source repository to add deb-src http://archive.raspbian.org/raspbian wheezy main contrib non-free rpi deb http://mirrordirector.raspbian.org/raspbian/ jessie main contrib non-free rpi deb http://archive.raspbian.org/raspbian jessie main contrib non-free rpi # Source repository to add deb-src http://archive.raspbian.org/raspbian jessie main contrib non-free rpi
Add preferences file
sudo nano /etc/apt/preferences
and insert
Package: * Pin: release n=wheezy Pin-Priority: 900 Package: * Pin: release n=jessie Pin-Priority: 300 Package: * Pin: release o=Raspbian Pin-Priority: -10
update package list
sudo apt-get update
Install gcc/g++ 4.8 from jessie repositories
sudo apt-get install -t jessie gcc-4.8 g++-4.8
To remove gcc/g++ alternative configuration (if there is any, there is none by default)
sudo update-alternatives --remove-all gcc sudo update-alternatives --remove-all g++
Install alternatives
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.6 20 sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8 50 sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.6 20 sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.8 50
Now 4.8 is your default compiler. You can verify it by
sudo gcc --version
If you want to change it, you can
sudo update-alternatives --config gcc sudo update-alternatives --config g++
