问题描述
我目前有一个结构如此的项目
项目|| ---- src/|||| ---- test.cpp|| ---- include/|||| ---- test.hpp|| ----.ycm_extra_conf.py 但是当 test.hpp
test.hpp 时，我无法让YouCompleteMe识别 #include"test.hpp" 这是我的:YcmDebugInfo

我遵循了完整的安装指南，并将外部clang设置为/usr/lib/libclang.so
我不知道是什么原因造成的.
解决方案
默认的 .ycm_extra_conf.py 不在附近的 include 目录中查找标头.
此查找是在 JDevlieghere的配置中完成的，我还为包含路径根添加了一个标志(在函数 FlagsForInclude 中):

project
|
|----src/
| |
| |----test.cpp
|
|----include/
| |
| |----test.hpp
|
|----.ycm_extra_conf.py
But I can't get YouCompleteMe to recognize test.hpp when it's include in test.cpp
#include "test.hpp"
This is the output of my :YcmDebugInfo
Printing YouCompleteMe debug information...

There are no errors present in the server log files, but the client logfile has a few errors that ultimately begins with this:

Other than this everything seems to be working although it will offer variables that are out of scope as suggestions when autocompleting (Suggests member variables of different classes).
I followed the full installation guide and set my external clang to /usr/lib/libclang.so
I have no idea what's causing this.
解决方案
The default .ycm_extra_conf.py doesn't look for headers in nearby include directories.
This lookup is done in JDevlieghere's configuration, which I adapted to also add a flag for the include path root (in function FlagsForInclude):
