I am running an Ubuntu 14.04-4 64bit. gcc --version returns

(Ubuntu 4.8.4-2ubuntu1~14.04.1) 4.8.4

Yet, I need version 4.8.2-10. What I tried:

  1. I found the specific gcc version in a debian snapshot repository.

  2. I adapted my /etc/apt/sources.list to contain the following two lines only:

    deb http://snapshot.debian.org/archive/debian/20131213T160912Z unstable main    
deb-src http://snapshot.debian.org/archive/debian/20131213T160912Z unstable main

  3. As suggested here I added the required key

  4. I did sudo apt-get -o Acquire::Check-Valid-Until=false update
  5. sudo apt-get remove gcc

  6. sudo apt-get install gcc. This returned:

     ...
 Preparing to unpack .../gcc_4%3a4.8.2-1_amd64.deb ...
 Unpacking gcc (4:4.8.2-1) ...
 Processing triggers for man-db (2.6.7.1-1ubuntu1) ...
 Setting up gcc (4:4.8.2-1) ...

Unfortunately, gcc --version still returned gcc (Ubuntu 4.8.4-2ubuntu1~14.04.1) 4.8.4

Removing and re-installing gcc-4.8 and gcc-4.8-base returned in an error (unmet dependencies) or a strange warning (uninstalling more than 700mb).

How can I install this specific gcc version?

You can find the packages you want over here and install them using gdebi.

You can have as many versions of gcc as you want, installed at the same time : The default versions for Ubuntu 14.04 are → →

$ sudo apt-get install g++-4.4 g++-4.6 g++-4.7 g++-4.8

... where "4.8" = version 4.8.2 is the system compiler, /usr/bin/{ gcc, g++ }

Using one of the other compilers, examples : $ gcc-4.4 file.c ,,, $ export CC=gcc-4.4 CXX=g++-4.4 && [other command] ,,, like $ export CC=gcc-4.4 CXX=g++-4.4 && ./configure

  • I don't see how this answers my question. How can I install the exact version I mentioned in my question? – langlauf.io May 19 '16 at 19:12
  • Not a good idea to replace the system compiler. But you can of course compile the older version 4.8.2, by building with configure option --program-suffix=482 http://www.linuxquestions.org/questions/linux-newbie-8/installing-gcc-4-8-2-on-opensuse-12-1-a-4175484799/#4 – Knud Larsen May 19 '16 at 19:22
  • ? Why do you want "4.8.2-10" . Seems that the original "April 2014 packages" were : cpp-4.8_4.8.2-19ubuntu1_amd64.deb, gcc-4.8-base_4.8.2-19ubuntu1_amd64.deb, gcc-4.8_4.8.2-19ubuntu1_amd64.deb, g++-4.8_4.8.2-19ubuntu1_amd64.deb → → https://mirror.umd.edu/ubuntu/pool/main/g/gcc-4.8/ – Knud Larsen May 20 '16 at 18:17

    I downloaded the package and did an dpkg -i gcc-4.8_4.8.2-19ubuntu1_amd64.deb. I got a "dependency problem" error. It says that gcc-4.8 depends on cpp-4.8 (= 4.8.2-19ubuntu1); however: Version of cpp-4.8 on system is 4.8.4-2ubuntu1~14.04.3 – langlauf.io May 20 '16 at 18:27

  • if I try to install cpp it says: cpp-4.8 depends on gcc-4.8-base (= 4.8.2-19ubuntu1); however: Version of gcc-4.8-base:amd64 on system is 4.8.4-2ubuntu1~14.04.3. – langlauf.io May 20 '16 at 18:29
  • Sorry, I don't understand what to do with the link. – langlauf.io May 20 '16 at 18:30

  • To install new packages, please first remove { gcc-4.8-base, gcc, g++, libstdc++-4.8-dev }. The issues will probably be : libgcc1, libstdc++ , which you cannot remove or downgrade, I think. – Knud Larsen May 20 '16 at 18:34
  • I got it installed. I needed the right order: gcc-4.8-base_4.8.2-19ubuntu1_amd64.deb cpp-4.8_4.8.2-19ubuntu1_amd64.deb libgcc-4.8-dev_4.8.2-19ubuntu1_amd64.deb gcc-4.8_4.8.2-19ubuntu1_amd64.deb – langlauf.io May 20 '16 at 18:36
