1、安装vundle
git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim
2、配置.vimrc
set nocompatible filetype off set rtp+=~/.vim/bundle/Vundle.vim call vundle#begin() Plugin 'VundleVim/Vundle.vim' Plugin 'tpope/vim-fugitive' call vundle#end() Bundle 'Valloric/YouCompleteMe' filetype plugin indent on
3、打开vim运行
:BundleInstall
4、安装必要工具
1、yum install gcc gcc-c++ make automake python-devel
2、安装CMake
wget http://www.cmake.org/cmake/resources/software.html tar -zxv -f cmake-*.*.*.*.tar.gz cd cmake-*.*.*.*.tar.gz ./bootstrap gmake gmake install
5、安装clang+llvm（这里用已经编译好的）
1、wget http://llvm.org/releases/3.5.1/clang+llvm-3.5.1-x86_64-fedora20.tar.xz xz -d clang+llvm-3.5.1-x86_64-fedora20.tar.xz tar xvf clang+llvm-3.5.1-x86_64-fedora20.tar cd clang+llvm-3.5.1-x86_64-fedora20 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： PATH=/usr/local/cmake/bin:/usr/clang_3_3/bin:$PATH export PATH 3、执行更新变量：source /etc/profile
6、进入YCM目录，运行
./install.sh –clang-completer
7、对~/.vimrc做配置
let g:ycm_global_ycm_extra_conf = '~/.vim/bundle/YouCompleteMe/third_party/y cmd/cpp/ycm/.ycm_extra_conf.py'
let g:ycm_confirm_extra_conf = 0
let g:ycm_semantic_triggers = {
\ 'c' : ['->', ' ', '.', ' ', '(', '[', '&'],
\ 'cpp,objcpp' : ['->', '.', ' ', '(', '[', '&', '::'],
\ 'perl' : ['->', '::', ' '],
\ 'php' : ['->', '::', '.'],
\ 'cs,java,javascript,d,vim,python,perl6,scala,vb,elixir,go' : ['.'],
\ 'ruby' : ['.', '::'],
\ 'lua' : ['.', ':']
\ }
