先上图，看效果！

YouCompleteMe的C++自己主动补全, syntastic的实时语法检測！

另外，里面还有缩进对齐显示的插件'Yggdroot/indentLine'，以及好看的状态栏显示插件'Lokaltog/vim-powerline'

1.用vundle下载YouCompleteMe，syntastic，indentLine和vim-powerline

Bundle 'Valloric/YouCompleteMe'

Bundle 'scrooloose/syntastic'

Bundle 'Lokaltog/vim-powerline'

Bundle 'Yggdroot/indentLine'

2.下载并安装clang

pacman -S clang (编译会得到/usr/lib/libclang.so)

3. 使用上一步编译得到的libclang库

cd ~
mkdir ycm_build
cd ycm_build

cmake -G "Unix Makefiles" -DEXTERNAL_LIBCLANG_PATH=/usr/lib/libclang.so. ~/.vim/bundle/YouCompleteMe/third_party/ycmd/cpp
make ycm_support_libs

4.配置.vimrc
