CentOS安装YCM

1、安装vundle

1. git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim

复制代码

2、配置.vimrc

1. set nocompatible  
   
2. filetype off
   
3. set rtp+=~/.vim/bundle/Vundle.vim
   
4. call vundle#begin()
   
5. Plugin 'VundleVim/Vundle.vim'
   
6. Plugin 'tpope/vim-fugitive'
   
7. call vundle#end()     
   
8. Bundle 'Valloric/YouCompleteMe'
   
9. filetype plugin indent on

复制代码

3、打开vim运行

1. :BundleInstall

复制代码

4、安装必要工具

1. 1、yum install gcc gcc-c++ make automake python-devel

复制代码

2、安装CMake

1. wget http://www.cmake.org/cmake/resources/software.html
   
2. tar -zxv -f cmake-*.*.*.*.tar.gz
   
3. cd cmake-*.*.*.*.tar.gz
   
4. ./bootstrap
   
5. gmake
   
6. gmake install

复制代码

5、安装clang+llvm（这里用已经编译好的）

1. 1、wget http://llvm.org/releases/3.5.1/clang+llvm-3.5.1-x86_64-fedora20.tar.xz
   
2. xz -d clang+llvm-3.5.1-x86_64-fedora20.tar.xz
   
3. tar xvf clang+llvm-3.5.1-x86_64-fedora20.tar
   
4. cd clang+llvm-3.5.1-x86_64-fedora20

复制代码

注：也可用tar xvf clang+llvm-3.5.1-x86_64-fedora20.tar.xz解压


2、在/etc/profile这个档案最尾端添加以下两行代码：

1. PATH=/usr/local/cmake/bin:/usr/clang_3_3/bin:$PATH
   
2. export PATH

复制代码

3、执行更新变量：source /etc/profile

6、进入YCM目录，运行

1. ./install.sh –clang-completer

复制代码

7、对~/.vimrc做配置

1. 
   
2. let g:ycm_global_ycm_extra_conf = '~/.vim/bundle/YouCompleteMe/third_party/y   cmd/cpp/ycm/.ycm_extra_conf.py'
   
3. let g:ycm_confirm_extra_conf = 0

复制代码

1. let g:ycm_semantic_triggers = {
   
2.   \   'c' : ['->', '    ', '.', ' ', '(', '[', '&'],
   
3. \     'cpp,objcpp' : ['->', '.', ' ', '(', '[', '&', '::'],
   
4. \     'perl' : ['->', '::', ' '],
   
5. \     'php' : ['->', '::', '.'],
   
6. \     'cs,java,javascript,d,vim,python,perl6,scala,vb,elixir,go' : ['.'],
   
7. \     'ruby' : ['.', '::'],
   
8. \     'lua' : ['.', ':']
   
9. \ }
