gcc-4.7 with Debian 8 Jessie - linux

Question

I use debian 8 Jessie, which has only gcc-4.9 available in the repositories. I tried to install gcc-4.7 in two ways without success.
First try
I tried installing gcc manually by downloading the file gcc-4.7.0.tar.gz
But when I install the dependency libraries (apt-get install Libmpc-dev libmpfr-dev libgmp-dev gcc-multilib)
the Debian installs, without asking gcc-4.9 and the compatible libraries with gcc-4.9.
I try run make for manual installation, but errors occur and it is not possible to install manually.
Second Try
I tried adding PPA repositories with gcc-4.7, in the file /etc/apt/sourc.list
Add-apt-repository ppa: ubuntu-toolchain-r / test as it teaches in this Link: https://askubuntu.com/questions/193513/problem-adding-a-ppa-to-install-gcc-4-7
When try apt-get install gcc-4.7 you are prompted to install several Dependencies ... when requesting to install the dependencies, the Below.
Root # vmhp110deb8: / home / user1 # apt-get install gcc-4.7 gcc-4.7-base
Reading package lists ... Done
Building dependency tree
Reading state information ... Done
Note, by selecting 'gcc-4.7-base' for regex 'gcc-4.7'
Package gcc-4.7-base is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
Is available from another source
E: Package 'gcc-4.7-base' has no installation candidate
Root # vmhp110deb8: / home / user1 # add-apt-repository ppa: ubuntu-toolchain-r / test
I tried to find a repository that has gcc-4.7-base, but then it asks Installation of other dependencies, and informs that it has not found
Libraries are Obsolete, etc.
Attempt not yet tested
Another idea that i had is download the Debian 7 Wheezy DVD (which I think Which has gcc-4.7 and all dependencies) and add as repository, For debian to find all dependencies of gcc.4.7 on DVD. But this idea i not have tested yet.
Could anyone help me with how I could install gcc 4.7 on debian 8?

As you can read here
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=765379
gcc-4.7 is not included in Debian Jessie
Maybe you can try this
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-4.7
EDIT : You already tries this. I didnt notice.
Try this manual:

I hope this helps to you :)
