How do I install gcc 4.7?

I wish to install gcc 4.7 so that I can use some c++11 features.

I downloaded the source, ran ./configure and was told I needed GMP. Downloaded the code for that, hit ./configure and was told I needed m4. But I already have m4 (least that is what synamptic tells me).

What is going on and how can I fix it?

You can try this PPA for installing gcc 4.7. Do note that it has packages only for 12.04 and not for 11.10.

Run the following commands in a terminal:

sudo add-apt-repository ppa:ubuntu-toolchain-r/test

sudo apt-get update

sudo apt-get install gcc-4.7

Or, if you prefer a graphical way of installing a PPA, take a look at What are PPAs and how do I use them?.
