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

Question

我为 VIM 安装了 YCM 和 syntastic，通常它们工作正常，但是当它检测到我的代码中的一些错误时我遇到了问题，它显示找不到一些头文件(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

我复制了一个.ycm_extra_conf.py到TOP，同时我也会在TOP生成tag和cscope文件，因此每次我在 TOP 上打开文件时，例如:

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

确保每次我都可以在 VIM 中添加 tag 和 cscope 文件。问题是，如果我打开driver.c，里面有头文件: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"

syntastic或YCM总是显示找不到common.h和debug.h，其他头文件没问题。

vimrc 文件中我的 YCM 和合成配置部分:

" 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

我的 .ycm_extra_conf.py 将 flags 变量写为:

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'
]

我是否设置了错误的标记？

从问题移到这里。

我发现了问题:

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./driver',
'-I./debug',
'-I./include',
]

我漏掉了一个逗号，路径应该是 ./xxx，还需要 '-I/usr/include' 和 '-I/usr/本地/包含'。
