Script to install devtoolset-based environment on Scientific Linux 6.x or CentOS 6.x

install-build-system.sh

#!/bin/sh

# This script is written for Scientific Linux 6.5 x64.
# Should also work for CentOS 6.5 (see below).
# It should be run as root (not sure whether sudo is fine also).

# boost version to install
boost_ver="1.55.0"

# This is only required with "Minimal" installation variant (for wget & scp).
yum -y install wget openssh-clients 

# download devtoolset repo information and store it
wget -O /etc/yum.repos.d/slc6-devtoolset.repo http://linuxsoft.cern.ch/cern/devtoolset/slc6-devtoolset.repo

# for CentOS we need to import a GPG key:
if [ -f /etc/centos-release ]
then
	rpm --import http://www.scientificlinux.org/documentation/gpg/RPM-GPG-KEY-cern
fi

# update repositories and software (not necessary)
yum -y update

# install devtoolset and needed packages (-y means don't ask user)
yum -y install                                                                      \
