CentOS安装YCM的方法

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' : ['.',':']

}
