cc1plus:错误:无法识别的命令行选项“-std=c++11"与 g++
我正在尝试使用 g++
和 -std=c++11
或 c++0x
标志进行编译.
I'm trying to compile using g++
and either the -std=c++11

flags.
但是,我得到了这个错误

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