推荐答案

从你的G++版本来看，你需要更新的很厉害.C++11 仅在 G++ 4.3 之后才可用.最新版本是 4.7.

Seeing from your G++ version, you need to update it badly. C++11 has only been available since G++ 4.3. The most recent version is 4.7.

在 G++ 4.7 之前的版本中，您必须使用 -std=c++0x，对于更新的版本，您可以使用 -std=c++11.

In versions pre-G++ 4.7, you'll have to use -std=c++0x, for more recent versions you can use -std=c++11.
