终于有了完整实现C++11的GCC 4.8.1.
给自己的系统升级吧。
下面的步骤可以安装GCC4.8.1, 内容来自:http://askubuntu.com/questions/312620/how-do-i-install-gcc-4-8-1-on-ubuntu-13-04
sudo add-apt-repository ppa:ubuntu-toolchain-r/test sudo update-alternatives --remove-all gcc sudo update-alternatives --remove-all g++ sudo apt-get install gcc-4.8 sudo apt-get install g++-4.8 sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8 20 sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.8 20 sudo update-alternatives --config gcc sudo update-alternatives --config g++ sudo apt-get update sudo apt-get upgrade -y sudo apt-get dist-upgrade
最后用gcc --version检查一下,果然是4.8.1.
