# Instructions for installing GCC 4.9 on various platforms.
# The commands show instructions for GCC 4.9, but any higher version will also work!

# Ubuntu (https://askubuntu.com/questions/466651/how-do-i-use-the-latest-gcc-on-ubuntu/581497#581497)
sudo apt-get install software-properties-common
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-4.9 g++-4.9
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.9 60 --slave /usr/bin/g++ g++ /usr/bin/g++-4.9

# CentOS (https://www.softwarecollections.org/en/scls/rhscl/devtoolset-3/)
sudo yum install centos-release-scl
sudo yum-config-manager --enable rhel-server-rhscl-7-rpms
sudo yum install devtoolset-3
scl enable devtoolset-3 bash

This is the correct command and it works! If you are on remote system and you do not have sudo access then this command should help. conda install https://anaconda.org/brown-data-science/gcc/5.4.0/download/linux-64/gcc-5.4.0-0.tar.bz2

This worked for me. Thanks for sharing!
