I need to install gcc 4.9 on ubuntu 15.10 because a library I really need (caffe and its cuda dependancies) requires such version or lower. I tried apt-get install gcc4.9 but it isn't working. Is there any way I can make it?

    "it isn't working" - what happens, exactly? FYI the package name is gcc-4.9 (note the hyphen)

The best way to correctly install gcc-4.9 is as follows:

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-4.9 g++-4.9

  • Doesn't the toolchain-r ppa typically only have newer versions than those in the standard repository? I only see gcc-5.2.1 there for Wily
