How I can safely upgrade gcc compiler v 4.4.3 to 4.6.1 under Ubuntu 10.04?

I tried:

$ sudo add-apt-repository ppa:ubuntu-toolchain-r/test
Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --secret-keyring /etc/apt/secring.gpg --trustdb-name /etc/apt/trustdb.gpg --keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --keyserver keyserver.ubuntu.com --recv 60C317803A41BA51845E371A1E9377A2BA9EF27F
gpg: requesting key BA9EF27F from hkp server keyserver.ubuntu.com
gpg: key BA9EF27F: public key "Launchpad Toolchain builds" imported

No success :(

  • try searching for gcc-4.6 from synaptic and install. Adding ppa upgrades the versions if they are already installed so you may try sudo apt-get upgrade Aug 23, 2011 at 7:01

    After adding a PPA, you should always run a sudo apt-get update in order to include the PPAs packages ;-)

The particular PPA you have pointed to in your question will update your GCC compiler from v4.4 to v4.5.

N.B. You need to run sudo apt-get update && sudo apt-get upgrade to uplift to this later version.

On launchpad I have found this PPA which looks promising to uplift lucid to gcc4.6 or this from the linaro maintainers.

Note - I'm not making any claims about the veracity of these PPAs. Please see possible related questions below.
