How do I backport/install a newer version of clang?

Question

I just want to install the newest version of clang http://packages.ubuntu.com/raring/clang-3.2

Does this mean I have to update my kernel to raring?

Answer 1

Clang 3.2.1 is currently available for 12.04(Precise), 12.10(Quantal) on Launchpad.

Clang 3.2.1 for 13.04(Raring) is available from the universe repository and can be installed normally through Synaptic or apt.

For 12.04, You can add the PPA to your repository through Synaptic using the following line(with instructions provided in the link below):

deb http://ppa.launchpad.net/kxstudio-team/builds/ubuntu precise main

Or, from the command line(Ctrl+Alt+t):

sudo add-apt-repository ppa:kxstudio-team/builds
sudo apt-get update
sudo apt-get install clang

For 12.10, you can either download the more recent deb files from here and install with sudo dpkg -i <package name> or install from a PPA.

To install the PPA on 12.10, run the following commands from the terminal(Ctrl+Alt+t):

sudo add-apt-repository ppa:georgekola/clang
sudo apt-get update
sudo apt-get install clang

In Synaptic, add the following line:

deb http://ppa.launchpad.net/georgekola/clang/ubuntu quantal main

Note for the 12.10 packages: The deb files are named 3.2-1~exp5ubuntu1 from February 2013, while the PPA is 3.2-1~exp1ubuntu3 from December 2012. Personally, I am using clang 3.2.1 on 12.04 and cannot currently give a recommendation over which package to use on 12.10.

• What are PPAs and how do I use them?
• Are PPA's safe to add to my system and what are some "red flags" to watch out for?
