YCM не находит мои заголовки?

У меня следующая структура папок:

.
├── include
│   └── ctset
│       ├── hashtable.h
│       └── set.h
└── src
    └── hashtable
        └── hashtable.c

А в hashtable.c включено #include "ctset/hashtable.h", но YCM постоянно говорит мне, что он не знает типы, которые я определил в заголовке, и использовал в источнике.

Мой .ycm_extra_conf.py - почти стандартный по умолчанию с некоторыми корректировками:

Предполагая наличие .ycm_extra_conf.py в корне вашего проекта. В MakeRelativePathsInFlagsAbsolute есть опечатка. Оператор if непосредственно после цикла for должен иметь отступ на другой уровень, поскольку оператор if выходит из внешнего цикла вместо внутреннего цикла.

Так что меняйся

for path_flag in path_flags:
  if flag == path_flag:
    make_next_absolute = True
    break

if flag.startswith( path_flag ):
    path = flag[ len( path_flag ): ]
    new_flag = path_flag + os.path.join( working_directory, path )
    break

Для

for path_flag in path_flags:
  if flag == path_flag:
    make_next_absolute = True
    break

  if flag.startswith( path_flag ):
    path = flag[ len( path_flag ): ]
    new_flag = path_flag + os.path.join( working_directory, path )
    break

Окончательный вариант .ycm_extra_conf.py должен выглядеть следующим образом.

Полезные команды отладки для YouCompleteMe: :YcmDebugInfo. Это покажет вам флаги компиляции, и вы увидите, что там не все флаги.
