YCM找不到我的标头? | YCM找不到我的标头

本文介绍了YCM找不到我的标头?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我具有以下文件夹结构:

I have the following folder structure:

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

在 hashtable.c 中，包含 #include"ctset/hashtable.h" ，但是YCM不断告诉我，它不知道我在标头中定义的类型以及在源代码中使用的类型.

And in hashtable.c the include #include "ctset/hashtable.h",but YCM keeps telling me that it doesn't know the types I defined in the header and use in the source.

我的 .ycm_extra_conf.py 几乎是经过一些调整的默认值:

My .ycm_extra_conf.py is almost the default one with some adjustments:

推荐答案

假定 .ycm_extra_conf.py 在项目的根目录中. MakeRelativePathsInFlagsAbsolute 中有一个错字.在for循环之后的if语句需要缩进另一级，因为if语句跳出了外循环而不是内循环.

Assuming the .ycm_extra_conf.py in the root of your project. There is a typo in MakeRelativePathsInFlagsAbsolute. The if statement directly after the for loop needs to be indented another level since the if statement breaks out of the outer loop instead of the inner loop.

所以改变

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

收件人

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

最终的 .ycm_extra_conf.py 应该看起来像这样.

The final .ycm_extra_conf.py should look like this.

YouCompleteMe有用的调试命令是:YcmDebugInfo .这将向您显示编译标志，并且您会看到并不是所有的标志都在那里.

Useful debugging commands for YouCompleteMe is :YcmDebugInfo. This shows you the compilation flags and you would see that not all the flags are there.
