ubuntu安装gcc/g++-4.1

Add to the end of /etc/apt/sources.list source from 10.04 (lucid)

deb http://mirrors.us.kernel.org/ubuntu/ lucid main universe

Then run

sudo apt-get update 

You have to specify version 4.1.2-27, as libstdc++6-4.1-dev has not been back ported to 4.1.2-29.

sudo apt-get install gcc-4.1=4.1.2-27ubuntu1 gcc-4.1-base=4.1.2-27ubuntu1 cpp-4.1=4.1.2-27ubuntu1 g++-4.1
