There is a Debian g++-4.4 package, but it's not Ubuntu. There are too many system-destroyed scary stories on the web.
How can I install g++ 4.4 on Ubuntu?
回答1:
Have a look at this URL. I installed gcc-4.4 (and g++-4.4) from there, which seem to be the most official group of hackers that actually put gcc-4.4 into an ubuntu .deb. Till now running without problems :
https://launchpad.net/~ubuntu-toolchain/+archive/ppa
Regards.

I recomend you install build-essential package that contains g++.
Type it in your terminal:
$ sudo apt-get install build-essential
Then confirm installation.

Debian packages should work on Ubuntu. It is based on Debian.
Edit: Try this :
sudo apt-get install gcc-snapshot

From your terminal type sudo apt-get install g++. It's been working great for me!
回答6:
If it is in a debian repository, it should would under Ubuntu no problem. If you would like to add a repository, simply follow the directions here.
回答7:
I would recommend against it. Requiring a newer version of g++ will require that if you use any new features of 4.4 then your users will also require a 4.4 runtime library. That being said, I would just download the source, ./configure --ALLMYOPTS&&make && sudo make install. If you want to make a gcc similar to the one shipped with Ubuntu, apt-get source gcc and look in debian/rules for their configure flags (they may be applied on multiple lines).
