gcc-4.7 with Debian 8 Jessie

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?

Answer 1

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: http://charette.no-ip.com:81/programming/2011-12-24_GCCv47/

I hope this helps to you :)
