How to configure .ycm_extra_conf.py for current project include PATH
提问by How Chen
I installed YCM and syntastic for VIM, normally they work fine, but I have problem when it detect some errors in my code, it shows that can NOT find some head files(which is my project head file).
我为 VIM 安装了 YCM 和 Syntastic，通常它们工作正常，但是当它在我的代码中检测到一些错误时出现问题，它表明找不到一些头文件（这是我的项目头文件）。
My directory tree shows below:
我的目录树如下所示：
TOP
├── debug
│?? ├── debug.c
│?? ├── debug.h
│?? ├── debug.mk
│?? └── instrument.c
├── driver
│?? ├── driver.c
│?? ├── driver_ddi.c
│?? ├── driver_ddi.h
│?? ├── driver.h
│?? └── driver.mk
├── include
│?? └── common.h
├── libs
├── Makefile
├── mw
│?? ├── manager.c
│?? └── mw.mk
└── root
?? ├── main.c
? ? └── root.mk
I copied a .ycm_extra_conf.pyto the TOP, meanwhile, I will generated tagand cscopefile at TOP as well, therefore each time I open file on TOP, like:
我复制了一个.ycm_extra_conf.py到 TOP，同时，我也会在 TOP生成tag并cscope归档，因此每次我在 TOP 上打开文件，例如：
howchen@host:~/Work/c/sample/src
-> gvim ./driver/driver.c
to make sure each time I can add tagand cscopefile in VIM. The problem is, if I open driver.c, which contain head files： driver.h, driver_ddi.h, debug.h, common.h, code like below:
确保每次我都可以在 VIM 中添加tag和cscope归档。问题是，如果我打开driver.c，其中包含头文件：driver.h, driver_ddi.h, debug.h, common.h, 代码如下：
#include <stdio.h>
#include <stdlib.h>
#include "math.h"
#include "common.h"
#include "debug.h"
#include "driver_ddi.h"
#include "driver.h"
the syntasticor YCMalways show it can NOT find common.hand debug.h, other head files are OK.
的syntastic或YCM总是显示无法找到common.h和debug.h其他头文件是否正确。
My YCM and syntastic config part in vimrc file:
我的 YCM 和 vimrc 文件中的 Syntastic 配置部分：
" YCM
" let g:ycm_extra_conf_globlist = ['~/.vim/bundle/YouCompleteMe/cpp/ycm/*','!~/*']
let g:ycm_global_ycm_extra_conf = '~/.vim/bundle/YouCompleteMe/cpp/ycm/.ycm_extra_conf.py'
" Syntastic
let g:syntastic_c_checkers=['make']
let g:syntastic_always_populate_loc_list = 1
let g:syntastic_check_on_open=1
let g:syntastic_enable_signs=1
let g:syntastic_error_symbol = '?'
let g:syntastic_warning_symbol = '?'
set statusline+=%#warningmsg#
set statusline+=%{SyntasticStatuslineFlag()}
set statusline+=%*gbar
My .ycm_extra_conf.pywrite flagsvariable as:
我的.ycm_extra_conf.py写flags变量为：
flags = [
'-Wall',
'-Wextra',
'-Werror',
'-Wc++98-compat',
'-Wno-long-long',
'-Wno-variadic-macros',
'-fexceptions',
'-DNDEBUG',
'-std=c99',
# ...and the same thing goes for the magic -x option which specifies the
# language that the files to be compiled are written in. This is mostly
# relevant for c++ headers.
# For a C project, you would set this to 'c' instead of 'c++'.
'-x', #I don't know if I need remove -x
'c',
'-isystem',
'../llvm/include',
'-isystem',
'../llvm/tools/clang/include',
'-I',
'.',
'-I',
'../driver'
'-I',
'../debug'
'-I',
'../include'
'-I',
'../include'
]
any wrong flags I set?
我设置的任何错误标志？

'-I./driver',
'-I./debug',
'-I./include',
]
I missed a comma and path should be ./xxx, also neeeeed '-I/usr/include', and '-I/usr/local/include'.
我错过了一个逗号，路径应该是./xxx，也neeeeed '-I/usr/include'，和'-I/usr/local/include'。
