how to install a certain compiler version (downgrading of g++)

[yinas]

hi there

currently i am trying to downgrade my version of g++ compiler in my ubuntu 9.10

using synaptic, deselecting current 4.4.1 version and adding desired 4.1.2 version will result in g++ not being recognized in terminal anymore :(

also
sudo apt-get g++
will only get me the latest 4.4.1

anyone got hints here, or useful links?

thx!

try out
sudo aptitude install build-essentials
