	CentOS 6.4 使用C++11，需要安装 devtools2 1.下载 repo 到本地 wget http://people.centos.org/tru/devtools-2/devtools-2.repo -O /etc/yum.repos.d/devtools-2.repo 复制代码 2.安装 yum install devtoolset-2-gcc devtoolset-2-binutils devtoolset-2-gcc-c++ 复制代码 3.创建链接 ln -s /opt/rh/devtoolset-2/root/usr/bin/* /usr/local/bin/ 复制代码 4.设置优先级 update-alternatives --install /usr/bin/gcc gcc /usr/local/bin/gcc 100 update-alternatives --install /usr/bin/g++ g++ /usr/local/bin/g++ 100 复制代码 5.或者用下面的方法启用 echo 'source /opt/centos/devtoolset-1.1/enable' >> /etc/profile source /opt/centos/devtoolset-1.1/enable 复制代码其中 3,4,5是保证生效，任选一个应该都可以，我依次做了三个。还有其它生效方法，如： scl enable devtoolset-2 bash In your .bash_profile , add at the bottom: echo "WARNING: devtoolset-2 is enabled!" . /opt/rh/devtoolset-2/enable 复制代码可以新打开一个终端，gcc -v 和　g++ -v 来查看版本变化 [me@localhost ~]$ gcc -v Using built-in specs.
