CentOS 6.5安装YouCompleteMe使用vim C/C++语法自动补全

史上最完整的CentOS 6平台安装YouCompleteMe教程,没有之一!

Ubuntu/Debian/Fedora比较好安装,各种软件包都比较新

CentOS6系列很难装,各种软件包版本太低了

新手不要尝试在CentOS6系上安装,会有一种挫败感!

Linux系统不是CentOS 6系列的少年， 请不要再往下看了。

阅读本文之前,我假设你知道什么是YouCompleteMe, 什么是C/C++语法补全.

好了,没什么废话可以再继续往下说的了,撸起袖子开始搞!

======================================================

步骤:

1, 安装操作系统

2, 文件下载

3, 更新vim

4, 安装ycm 和 Vundle

5, 编译clang

6, 编译ycm_core

7, 效果图

8, 清理工作

1, 安装操作系统:

http://archive.kernel.org/centos-vault/6.5/isos/x86_64/CentOS-6.5-x86_64-bin-DVD1.iso#我习惯尽量不使用root权限,创建普通用户
[root@CentOS ~]# useradd chunli
[root@CentOS ~]# passwd chunli
[root@CentOS ~]# vim /etc/sudoers

[root@CentOS ~]# logout
chunli@ubuntu ~ ssh chunli@11.11.11.4

[chunli@CentOS ~]$

2, 文件下载

[chunli@CentOS ~]$ wget --no-check-certificate https://cmake.org/files/v3.8/cmake-3.8.0-rc2.tar.gz
[chunli@CentOS ~]$ wget --no-check-certificate https://www.python.org/ftp/python/2.7.13/Python-2.7.13.tar.xz
[chunli@CentOS ~]$ wget ftp://ftp.gnu.org/gnu/gcc/gcc-6.3.0/gcc-6.3.0.tar.bz22017.03.11 写博客时,最新的llvm还是3.9.1,
2017.03.14 今天来更新博客发现llvm 4.0.0已经发布了
尼玛,更新真快.....
[chunli@CentOS ~]$ mkdir llvm-3.9.1
[chunli@CentOS ~]$ cd llvm-3.9.1
[chunli@CentOS llvm-3.9.1]$ wget http://releases.llvm.org/3.9.1/llvm-3.9.1.src.tar.xz
[chunli@CentOS llvm-3.9.1]$ wget http://releases.llvm.org/3.9.1/cfe-3.9.1.src.tar.xz
[chunli@CentOS llvm-3.9.1]$ wget http://releases.llvm.org/3.9.1/compiler-rt-3.9.1.src.tar.xz
[chunli@CentOS llvm-3.9.1]$ wget http://releases.llvm.org/3.9.1/clang-tools-extra-3.9.1.src.tar.xz

3, 更新vim

Ensure that your version of Vim is at least 7.4.143 and that it has support for Python 2 or Python 3 scripting.

#查看系统的vim ,版本太低了!
[chunli@CentOS ~]$ vim --version
VIM - Vi IMproved 7.2 (2008 Aug 9, compiled Apr  5 2012 10:12:47)#在线升级vim
[chunli@CentOS ~]$ sudo yum update vim        #提示是7.4.629
[chunli@CentOS ~]$ vim --version
VIM - Vi IMproved 7.4 (2013 Aug 10, compiled Dec 21 2016 17:06:34)
Included patches: 1-207, 209-629[chunli@CentOS ~]$ vim --version| grep python  #查看vim对python的支持
+cryptv          +linebreak       +python/dyn      +viminfo
+cscope          +lispindent      -python3         +vreplace
vim 问题解决了!!!

4,安装ycm, vundle

Install YCM with Vundle (or Pathogen, but Vundle is a better idea).

With Vundle, this would mean adding a Plugin 'Valloric/YouCompleteMe' line to your vimrc.

这个步骤简单,一般不会有错

[chunli@CentOS ~]$ sudo yum install git
[chunli@CentOS ~]$ git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim
[chunli@CentOS ~]$ mv ~/.vimrc  ~/.vimrc.back   #备份默认的vim配置文件
[chunli@CentOS ~]$ vim ~/.vimrc    #创建新的vim配置文件，键入如下7行filetype off
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()
Plugin 'VundleVim/Vundle.vim'
Plugin 'Valloric/YouCompleteMe'
call vundle#end()
filetype plugin indent on   [chunli@CentOS ~]$
[chunli@CentOS ~]$ vim +PluginInstall +qall  #出现一个vim的窗口，下载大约15分钟
[chunli@CentOS ~]$ echo $?
[chunli@CentOS ~]$ du -sh ~/.vim/bundle/YouCompleteMe/  #看看下载了什么
221M    /home/chunli/.vim/bundle/YouCompleteMe/

5 源码编译clang !

Complete this step ONLY if you care about semantic completion support for C-family languages. Otherwise it's not necessary '

Download the latest version of libclang,YCM is designed to work with libclang version 3.9 or higher.

欢迎来到极易出错的地方, 源码编译clang !

7 效果图

历经千辛万苦, ycm终于可以正常使用了!

先来几种自动补全图!!!!

结构体补全1

结构体补全2

头文件补全

语法检查

看看补全Linux系统结构体补全怎么样

将C头文件路径写入配置

[chunli@CentOS ~]$ vim ~/.vim/.ycm_extra_conf.py
在flags中尾端追加2行
'-isystem',
'/usr/include/',

1级补全

2级补全,看起来还不错

3 无法补全结构体中的函数指针成员,必须自己敲

ycm的工作模式,很明显是CS模式

没有运行vim时,没有ycm进程
[chunli@CentOS ~]$ sudo ps aux| grep ycm
chunli    3408  0.0  0.0   4356   744 pts/3    S+   01:40   0:00 grep ycm

8 清理工作:

[chunli@CentOS ~]$ rm -rf cmake-3.8.0-rc2*
[chunli@CentOS ~]$ rm -rf Python-2.7.13.*
[chunli@CentOS ~]$ rm -rf python-2.7/
[chunli@CentOS ~]$ rm -rf clang3.9/
[chunli@CentOS ~]$ rm -rf llvm-3.9.1/
[chunli@CentOS ~]$ rm -rf gcc-6.3.0*
[chunli@CentOS ~]$ rm -rf ycm_build/

clang 编译好了之后,不用安装,仅仅为了得到libclang.so

python2.7 也是临时的,作为clang的依赖不需要安装什么第三方库

gcc 也可以是临时的, 用来编译clang, 还可以得到libstdc++.so

奇怪的问题,我前面已经替换过这个文件/usr/bin/python,我以为清理python2.7.13后vim不能用了.

但是vim 的自动补全没有任何影响,来看看/usr/bin/python --version 又是2.6版本, 郁闷!

难道是安装python-devel时自动恢复/usr/bin/python为python2.6了 ?
