vim 智能提示插件 YouCompleteMe安装

按照网上的教程安装该软件，没有一篇是成功的（也有可能是没找对）。自己从网上东拼西凑的，终于让自己的vim智能识别了。

1. 升级 vim: (ubuntu)

sudo add-apt-repository ppa:jonathonf/vim
sudo apt update
sudo apt install vim

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

3.下载ycm
cd ~/.vim/
git clone --recursive https://github.com/Valloric/YouCompleteMe.git
cd ~/.vim/bundle/YouCompleteMe

git submodule update --init --recursive

4. 安装libclang

apt-get install llvm-3.9 clang-3.9 libclang-3.9-dev libboost-all-dev

5. 编译ycm_core库
mkdir 123 && cd 123

cmake -G "Unix Makefiles" -DUSE_SYSTEM_BOOST=ON -DUSE_SYSTEM_LIBCLANG=ON . ~/.vim/bundle/YouCompleteMe/third_party/ycmd/cpp
或者
cmake -G "Unix Makefiles" -DUSE_SYSTEM_BOOST=ON -DEXTERNAL_LIBCLANG_PATH=/usr/lib/x86_64-linux-gnu/libclang-3.9.so . ~/.vim/bundle/YouCompleteMe/third_party/ycmd/cpp  #未验证

cmake --build . --target ycm_core --config Release

6. 配置
#perl警告处理
echo "export LC_ALL=C" >> /root/.bashrc
source /root/.bashrc

cp ~/.vim/bundle/YouCompleteMe/third_party/ycmd/examples/.ycm_extra_conf.py ~/.vim/

配置vimrc
"~/.vimrc
let g:ycm_server_python_interpreter='/usr/bin/python2.7'      " 当时编译python的版本
let g:ycm_global_ycm_extra_conf='~/.vim/.ycm_extra_conf.py'
