关于YouCompleteMe

编译安装 --all选项指所有

vivo@vivo-ThinkCentre-M6600t-N000:~/.vim/plugged/YouCompleteMe$ ./install.sh --clang-completer --clangd-completer --ts-completer --java-completer

2.--java-completer中如果jdt无法下载修改文件,从https服务器上获取: third_party/ycmd/build.py

3.配置在具体的项目中，在项目的根目录中放一个.ycm_extra_conf.py，并且加上头文件目录的配置，比如， flags = [ '-Wall', '-Wextra', '-Werror', '-Wno-long-long', '-Wno-variadic-macros', '-fexceptions', '-DNDEBUG', ... '-I', '/home/macduan/work/opensource/brpc/src', '-I', '/home/macduan/work/opensource/brpc/src/brpc', '-I', '/home/macduan/work/opensource/brpc/src/bthread', '-I', '/home/macduan/work/opensource/brpc/src/butil', '-I', '/home/macduan/work/opensource/brpc/src/bvar', '-I', '/home/macduan/work/opensource/brpc/src/json2pb', '-I', '/home/macduan/work/opensource/brpc/src/mcpack2pb']

Linux内核 flags = [ '-Wall', '-Wextra', '-Werror', '-Wc++98-compat', '-Wno-long-long', '-Wno-variadic-macros', '-fexceptions', '-DNDEBUG',

added for kernel compile

'-Wundef', '-Wstrict-prototypes', '-Wno-trigraphs', '-fno-strict-aliasing', '-fno-common', '-Werror-implicit-function-declaration', '-Wno-format-security',

THIS IS IMPORTANT! Without a "-std=" flag, clang won't know which

language to use when compiling headers. So it will guess. Badly. So C++

headers will be compiled as C headers. You don't want that so ALWAYS specify

a "-std=".

For a C project, you would set this to something like 'c99' instead of

'c++11'.

'-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', 'c', '-I', 'include/', '-I', 'include/generated', '-I', 'include/asm-generic/', '-I', 'arch/x86/include', '-I', 'arch/x86/include/generated', '-I', 'arch/x86/include/uapi', '-I', 'arch/x86/include/generated/uapi', ]
