Richard Holloway's answer to this thread nicely explains how to upgrade from 4.6.3 to 4.7.0 (on 12.04, in my case) but I would like to upgrade to 4.7.1, which has been available for awhile. However there is no package g++-4.7.1 and I don't know otherwise how to do it, does anyone else?

Wow, this was excruciating. Here's how I did it (NB, for a 32-bit system):

  1. $sudo apt-get install gcc-multilib

  2. $sudo apt-get install m4

  3. Download mpfr, configure, make, make install

  4. Download gmp, configure, make, make install

  5. Download mpc, configure, make, make install

  6. In order to compensate for insufficient path information, added this to .bashrc

export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH

export LIBRARY_PATH=/usr/lib/i386-linux-gnu export

export C_INCLUDE_PATH=/usr/include/i386-linux-gnu export

export CPLUS_INCLUDE_PATH=/usr/include/i386-linux-gnu

the former I got from here and the latter from here, modified appropriately for my install locations.

.7. Add these symlinks for the same reason:

$sudo ln -s /usr/include/i386-linux-gnu/gnu/stubs-32.h /usr/include/gnu

$sudo ln -s /usr/lib/i386-linux-gnu/crti.o /usr/lib/crti.o

$sudo ln -s /usr/lib/i386-linux-gnu/crt1.o /usr/lib/crt1.o

$sudo ln -s /usr/lib/i386-linux-gnu/crtn.o /usr/lib/crtn.o

$sudo ln -s /usr/local/lib/libmpc.so.3 /usr/lib/libmpc.so.3

.8. Download g++-4.7.1, configure, make, make install

Try to compile g++-4.7.1

List of mirrors:

http://gcc.gnu.org/mirrors.html

Select mirror, click releases and search for gcc-4.7.1.

Download source, and compile.
