[Rocks Cluster]: g++ 4.7 to centos

g++ 4.7 to centos

cd /etc/yum.repos.d

wget http://people.centos.org/tru/devtools/devtools.repo 

yum --enablerepo=testing-devtools-6 install devtoolset-1.0

Since you're running g++ manually (as opposed to through make), you'll need to update your $PATH variable so your shell will use the new gcc, g++, etc. binaries:




export PATH=/opt/centos/devtoolset-1.0/root/usr/bin/:$PATH





At this point, your g++ should be version 4.7.0




$ g++ --version
g++ (GCC) 4.7.0 20120507 (Red Hat 4.7.0-5)
