如何为当前项目include PATH配置.ycm_extra_conf.py

我安装了YCM和syntastic for VIM，通常它们工作正常，但当它检测到我的代码中的一些错误时，我遇到了问题，这表明找不到一些头文件（这是我的项目头文件）

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

我在顶部复制了一个

.ycm\u extra\u conf.py

，同时，我也会在顶部生成

标记

和

cscope

文件，因此每次打开顶部的文件，如：

howchen@host:~/Work/c/sample/src
-> gvim ./driver/driver.c

确保每次我都可以在VIM中添加

标记

和

cscope

文件。问题是，如果我打开

driver.c

，其中包含头文件：

driver.h

，

driver\u 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"

My

.ycm\u extra\u conf.py

write

flags

变量为：

" 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

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',

'-isystem',
'../llvm/tools/clang/include',
'-I',
'.',
'-I',
'../driver'
'-I',
'../debug'
'-I',
'../include'
'-I',
'../include'
]

我设置了错误的标志吗？

从问题移到这里

我发现了问题：

'-Wall',
'-Wextra',
'-Werror',
'-Wc++98-compat',
'-Wno-long-long',
'-Wno-variadic-macros',

'-x', #I don't know if I need remove -x
'c',
'-isystem',
'../llvm/include',
'-isystem',
'../llvm/tools/clang/include',
'-I./driver',
'-I./debug',
'-I./include',
]

我漏掉了一个逗号，路径应该是

/xxx

，也需要

'-I/usr/include'

，和

'-I/usr/local/include'
，再次尝试他们的问题跟踪器。@romainl，我尝试过，但无应答Syntastic找不到头文件时会出现什么症状？底部第4行缺少逗号如果.ycm_extra_conf.py位于顶部目录，则调试路径应为./debug，而不是../debug。ycm使用基于.ycm_extra_conf.py文件路径的相对路径。
