A bit of background: I'm a software developer, been doing linux dev since the mid-90's. I recently inherited the tasks of "build machine guy", and I want to move us off Centos 5.x and into Ubuntu 12.04.
But I have a problem: we use Bitbake to generate our solid-image for the embedded target, and it turns out the infrastructure of the bitbake version we use is closely coupled with gcc 4.1.2. That doesn't leave many options: If I am to migrate to Ubuntu 12.x, I must have gcc 4.1.2. Moving us into the present bitbake and gcc would require an significant effort that is beyond what I have budgeted for time, today.
So in my attempts at making this happen, I added the following lines to /etc/apt/sources.list:
I did an apt-get update; then tried to install:
deb http://archive.ubuntu.com/ubuntu/ lucid universe
deb-src http://archive.ubuntu.com/ubuntu/ lucid universe
I had assumed I could install the package, then use something like
# apt-get install gcc-4.1

Is it possible to get gcc 4.1 installed on Ubuntu 12.04?
An alternative: is it possible to install gcc 4.1 somewhere on /opt so that the toolchain knows its installed in /opt (libs, headers, etc)? If so, what would the specific steps be for 12.04?
