vim .ycm_extra_conf.py
修改flags

flags = [
'-std=gunc99',
'-x',
'c',
'-isystem',
'/usr/include/',
'-isystem',
'/home/chunli/work/01_第三方共享库头文件路径/',
'-isystem',
'/home/chunli/work/01_chunli/08_本项目头文件路径/',

]

ycm_extra_conf.py 路径中不要有中文, 否则打开vim出现以下报错
UnicodeEncodeError: 'ascii' codec can't encode characters in position 37-40: ordinal not in range(128)

解决办法

1,
在.ycm_extra_conf.py文件首行添加
# encoding=utf8

2,创建文件，写入信息
chunli@CentOS~$ sudo find / -name 'site-packages'
/usr/share/xemacs/site-packages
/usr/lib/python2.6/site-packages

chunli@CentOS~$ sudo vim /usr/lib/python2.6/site-packages/sitecustomize.py
import sys
sys.setdefaultencoding('utf-8')
chunli@CentOS~$

#需要在vimrc 开启let g:ycm_show_diagnostics_ui = 0 "关闭语法提示
