采用ycmd模式 加上 前面介绍的company-mode

参考，重点内容已经截出来

Building

[Clients commonly build and set up ycmd for you; you are unlikely to need tobuild ycmd yourself unless you want to build a new client.]

This is all for Ubuntu Linux. Details on getting ycmd running on other OS‘s can befound in YCM‘s instructions (ignore the Vim-specific parts).

First, install the dependencies:

sudo apt-get install build-essential cmake python-dev

When you first clone the repository you‘ll need to update the submodules:

git submodule update --init --recursive

Then run ./build.py --clang-completer --omnisharp-completer --gocode-completer.This should get you going.

For more detailed instructions on building ycmd, see YCM‘sinstructions (ignore the Vim-specific parts).

编译好后，会出现一个在ycmd目录下出现一个同名的ycmd目录。这个路径等会需要。

这个不再细说。

;; company mode
(add-hook ‘c++-mode-hook ‘global-company-mode)

;; ycmd
(require ‘ycmd)
(add-hook ‘c++-mode-hook ‘ycmd-mode)
(set-variable ‘ycmd-server-command ‘("python" "/home/dean/work/software/ycmd/ycmd"))
(set-variable ‘ycmd-extra-conf-whitelist ‘("/home/dean/work/gitlab/gitlab.com/cppwizard/console/*"))

(require ‘company-ycmd)
(company-ycmd-setup)

文件可以从ycmd的example目录中复制出来，名为.ycm_extra_conf.py，放在这里

/home/dean/work/gitlab/gitlab.com/cppwizard/console/*

flags = [
‘-Wall‘,
‘-Wextra‘,
‘-Werror‘,
‘-fexceptions‘,
‘-DNDEBUG‘,
# 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=c++11‘,
# ...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++‘,
‘-isystem‘,
‘/usr/include‘,
‘-isystem‘,
‘/usr/local/include‘,
‘-isystem‘,
‘/home/dean/work/gitlab/gitlab.com/cppwizard/console/include‘
