Eclipse4.5.1 Mars C++11 编译出错解决方法

在Centos7.2下用Eclipse Mars.1 编译 C++ 11项目(GCC版本为4.8.2),程序异常如下:/usr/include/c++/4.8.2/bits/c++0x_warning.h:32:2: error: #error This file requires compiler and library support for the ISO C++ 2011 standard. This support is currently experimental, and must be enabled with the -std=c++11 or -std=gnu++11 compiler options.

 #error This file requires compiler and library support for the \

解决方法如下:​

菜单:

Window -> Preferences -> C/C++ -> Build -> Settings -> Discovery -> CDT GCC Build-in Compiler Settings

添加后的Command to get compiler specs内容为:${COMMAND} ${FLAGS} -E -P -v -dD -std=c++11 "${INPUTS}"

​红色字体为新增加的内容,注意带空格,直接复制即可。

右键项目属性:

Properties -> C/C++ Build -> Settings -> Tool Settings -> GCC C++ Compiler == Dialect

添加 -std=c++11 到 Other dialect flags 或者列表里面选择 ISO C++11(-std=c++0x)


然后就大功告成啦:直接按ctrl+b快捷键重新编译项目​
