'Ubuntu 14.04 install gcc-4.5 and g++4.5

I'm trying to install gcc-4.5 and g++-4.5 on Ubuntu 14.04 sudo apt-get install gcc-4.5 g++-4.5 gcc-multilib g++-multilib but the following errors appeared:

Package gcc-4.5 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

Package g++-4.5 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'gcc-4.5' has no installation candidate
E: Package 'g++-4.5' has no installation candidate

Can anyone tell me what I need to do?

gcc-4.5 or g++4.5 is not in most Ubuntu software distributions. If you are trying to get exactly this version, see gcc releases and successful builds.

Another option is to use “PPA for Ubuntu Toolchain Uploads (restricted)” team's edition. In your case, add

deb http://ppa.launchpad.net/ubuntu-toolchain-r/ppa/ubuntu trusty main 
deb-src http://ppa.launchpad.net/ubuntu-toolchain-r/ppa/ubuntu trusty main

to your source list, and run sudo apt-get update. You'll be able to use sudo apt-get install gcc-4.5.
