I would like to install from repository (without compilation from source) the latest g++ 4.7.1 on Ubuntu 12.04. I know I can install g++ 4.7.0 according to this tutorial.
I have also found the g++ 4.7.1 exists in the same repository as mentioned in the tutorial here. If there is newer version in the repository, why the previously installed version (4.7.0) is not updated when running the "Update Manager"? How do I install 4.7.1? Thank you
