How can I install GCC 4.8 on Raspberry Pi? Do I need to compile it from source? Should I update from Raspbian wheezy to a newer version?

In 2015-02-16-raspbian-wheezy is gcc-4.8 already as package (4.8.2), but not default. You can install it apt-get install gcc-4.8 g++-4.8 and then change the links in /usr/bin/

As long as your Raspberry Pi is up to date, then you can just download and patch GCC 4.8 to run on you Raspberry Pi.

  1. Download GCC sources

    $ wget ftp://ftp.fu-berlin.de/unix/languages/gcc/snapshots/LATEST-4.8/*.bz2

  2. Extract sources

    $ tar xf gcc-4.8-20120826.tar.bz2

  3. Patch sources

    We need to get and apply two debian specific patches for GCC:

    $ wget http://anonscm.debian.org/viewvc/gcccvs/branches/sid/gcc-4.7/debian/patches/armhf-triplet.diff?view=co -O armhf-triplet.diff
$ wget http://anonscm.debian.org/viewvc/gcccvs/branches/sid/gcc-4.7/debian/patches/gcc-multiarch-trunk.diff?view=co -O gcc-multiarch-trunk.diff
$ cd gcc-4.8-20120826
$ patch -p2 -i ../armhf-triplet.diff
$ patch -p2 -i ../gcc-multiarch-trunk.diff

    Note: There will be a failed patch in libgcc, don't worry about it, as it's already been applied to gcc-4.8.

  4. Recreate .autoconf files:

    $ cd gcc
$ autoconf2.64
$ cd ../libjava
$ autoconf2.64
$ cd ../

  5. Compile and install GCC: configure; make; make install

In case any of these options haven't worked for you (or you're running something newer), you can try this. I'm running Raspian with desktop (without included software) on a Raspberry Pi 4.

I went into /etc/apt/ and modified sources.list. The second line in my file says:

# Uncomment line below then 'apt-get update' to enable 'apt-get source'
deb-src http://raspbian.raspberrypi.org/raspbian/ buster main contrib non-free rpi

After that, run sudo apt-get update and sudo apt-get upgrade, then finally:

sudo apt-get install gcc-4.8

***Side note: If you're also wanting to install g++-4.8 (like I was, for tensorflow), you'll need to add these two lines to your sources.list file:

deb http://mirrordirector.raspbian.org/raspbian/ wheezy main contrib non-free rpi
deb http://mirrordirector.raspbian.org/raspbian/ jessie main contrib non-free rpi

Again, sudo apt-get update && sudo apt-get upgrade, and then:

sudo apt-get install g++-4.8

I tried the above -- ran into several issues. This might be easier (I'm trying it now):
