打造linux下的source insight--YouCompleteMe安装

1.安装前准备
sudo apt-get install build-essential cmake
sudo apt-get install python-dev
sudo apt-get install git


2.Vundle的安装
git clone https://github.com/gmarik/Vundle.vim.git ~/.vim/bundle/Vundle.vim


3.修改.vimrc文件,以下是我的修改方案
runtime! debian.vim
"设置编码
set encoding=utf-8
set fencs=utf-8,ucs-bom,shift-jis,gb18030,gbk,gb2312,cp936
set fileencodings=utf-8,ucs-bom,chinese
 
"语言设置
set langmenu=zh_CN.UTF-8
"显示行号
set nu!
"设置语法高亮
syntax enable
syntax on
 
"设置配色方案
"colorscheme torte
 
"可以在buffer的任何地方使用鼠标
set mouse=a
set selection=exclusive
set selectmode=mouse,key
 
"高亮显示匹配的括号
set showmatch
 
"去掉vi一致性
set nocompatible
 
"设置缩进
set tabstop=4
set softtabstop=4
set shiftwidth=4
set autoindent
set cindent
if &term=="xterm"
    set t_Co=8
    set t_Sb=^[[4%dm
    set t_Sf=^[[3%dm
endif




set nocompatible
filetype off
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#rc()
Bundle 'gmarik/vundle'
Bundle 'taglist.vim'


Bundle 'Valloric/YouCompleteMe'
Bundle 'Valloric/ListToggle'
Bundle 'scrooloose/syntastic'


filetype plugin indent on


""""""""""""YCM""""""""""""""""""""
let g:ycm_global_ycm_extra_conf = '~/.vim/bundle/YouCompleteMe/cpp/ycm/.ycm_extra_conf.py'
let g:ycm_collect_identifiers_from_tags_files = 1
let g:ycm_seed_identifiers_with_syntax = 1
let g:ycm_confirm_extra_conf = 0


"Settings for tagslist
let Tlist_Use_Right_Window = 1"让taglist窗口出现在Vim的右边
let Tlist_File_Fold_Auto_Close = 1
"当同时显示多个文件中的tag时，设置为1，可使taglist只显示当前文件tag，其它文件的tag都被折叠起来。
let Tlist_Show_One_File = 1"只显示一个文件中的tag，默认为显示多个
let Tlist_Sort_Type ='name'"Tag的排序规则，以名字排序。默认是以在文件中出现的顺序排序
let Tlist_GainFocus_On_ToggleOpen = 1"Taglist窗口打开时，立刻切换为有焦点状态
let Tlist_Exit_OnlyWindow = 1"如果taglist窗口是最后一个窗口，则退出vim
let Tlist_WinWidth = 32"设置窗体宽度为32，可以根据自己喜好设置


4.插件安装
打开vim，并运行:PluginInstall


5.安装YouCompleteMe插件
cd ~/.vim/bundle/YouCompleteMe/
./install.sh --clang-completer


6.如果~/.vim/bundle/YouCompleteMe/cpp/ycm/.ycm_extra_conf.py找不到文件
需要自己创建目录和相关文件，.ycm_extra_conf.py如下
import os
import ycm_core


# These are the compilation flags that will be used in case there's no
# compilation database set (by default, one is not set).
# CHANGE THIS LIST OF FLAGS. YES, THIS IS THE DROID YOU HAVE BEEN LOOKING FOR.

# 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=<something>".
# 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.

# Set this to the absolute path to the folder (NOT the file!) containing the

#   set( CMAKE_EXPORT_COMPILE_COMMANDS 1 )
# to your CMakeLists.txt file.
#
# Most projects will NOT need to set this to anything; you can just change the
# 'flags' list of compilation flags. Notice that YCM itself uses that approach.
