  question, vim

图片描述

In a situation like the above, every time you use the new features of C++11, you will be prompted.
May I know how to make vim’s syntax hints compatible with C++11?
Is this prompt function self-contained or plug-in function?
Plug-in, I installed YCM.

let g:syntastic_cpp_compiler_options = ‘ -std=c++11 -stdlib=libc++’
