I've been trying to get an old version of GCC for my Ubuntu but I can't find any working way to achieve that.
I'd like to use the version 4.1.2 of GCC, and I currently got the 4.7.2.
How may I install GCC 4.1.2 ?

I have created a PPA that contains a build of GCC 4.7 for Precise here:

(Click here for instructions on using PPAs.)
To backport a package from one release to another is a relatively simple process assuming you have a Launchpad account and have registered your GPG key there.
Make sure you have the ubuntu-dev-tools package installed:
sudo apt-get install ubuntu-dev-tools
The syntax for running the backport command looks something like this:
backportpackage -s [new_release] -d [old_release] -u [ppa] [package_name]
The command above will backport [package_name] from [new_release] to [old_release]and upload it to [ppa]. Note that in this particular case you will need to backport not only gcc-4.7 but also gcj-4.7 and gcc-defaults in that order.
Assume a 64bits Ubuntu 16.04 .
Available is {gcc-3.4.6, g++-3.4.6} ... This version is very close to gcc-4.1.2 .

Clik the packages, compat-gcc34-3.4.6-ubuntu1204-1_amd64.deb and compat-gcc-34-c++_3.4.6-20_amd64.deb : They will then be installed.
Using, examples : 1) $ export CC=gcc34 CXX=g++34 && [other command] ... like 2) $ export CC=gcc34 CXX=g++34 && ./configure .... and 3) $ gcc34 file.c
? Which application is it that requires gcc-4.1.2 ?
