Currently g++ 4.4.3 is installed on my Ubuntu, but I want to update it to 4.6.3 version. When I search "g++" in synaptic package manager there is nothing about newer versions.

How can I update my g++ then?

The repository may not contain the newest version. Either try backports or install from source. – harisibrahimkv May 4 '12 at 10:49
I have ubuntu 12.04 and I have installed the 4.6.3 version. Click on the 'Reload' button on the top left of synaptic and try again. – hakermania May 4 '12 at 10:49

@hakermania: Reload didn't change version. – a-z May 4 '12 at 10:58
The best thing to do would be to install the g++ to a non-standard location (Do this by running ./configure --prefix=<path_to_install_to>) and then append that path to the standard PATH variable. Refer to this… . After you are done installing, you can remove your older g++ using "sudo apt-get remove g++". – harisibrahimkv May 4 '12 at 12:07

For latest version of gcc/g++ you can add this ppa-ppa:ubuntu-toolchain-r/test via Synaptic Package Manager and then press reload button.You should now see the latest version of g++ in the list of packages.
