• 安装YouCompleteMe插件
  vim
:PlugInstall

提示:

• Q1:

• A1:

mkdir -p ~/.vim_runtime/sources_non_forked/ack.vim/plugged/YouCompleteMe/third_party/go/src/golang.org/x
cd ~/.vim_runtime/sources_non_forked/ack.vim/plugged/YouCompleteMe/third_party/go/src/golang.org/x
git clone https://github.com/golang/tools.git

cd ~/.vim_runtime/sources_non_forked/ack.vim/plugged/YouCompleteMe/third_party/ycmd/third_party/go/src/golang.org/x
git clone https://github.com/golang/tools.git

cd ~/.vim_runtime/sources_non_forked/ack.vim/plugged/YouCompleteMe
git submodule update --init --recursive

• 安装虚拟环境
  pip3 install virtualenv
cd ~/.vim_runtime/sources_non_forked/ack.vim/plugged/YouCompleteMe
virtualenv venv
source venv/bin/activate

提示：

• 退出venv
  deactivate

• 支持C
  ./install.py --clang-completer
• 新建项目文件夹
  cd ~ && mkdir mydata
cd mydata
virtualenv venv
source venv/bin/activate
• 保证cpp/ycm中有.ycm_extra_conf.py
  cp ~/.vim_runtime/sources_non_forked/ack.vim/plugged/YouCompleteMe/third_party/ycmd/.ycm_extra_conf.py ~/.vim_runtime/sources_non_forked/ack.vim/plugged/YouCompleteMe/third_party/ycmd/cpp/ycm/
• 安装ctags
  yum install ctags -y
  源码位置生成tags
  ctags -R *

参阅：

• 使用VIM插件ctags来阅读C代码

• 编译YCM需要的ycm_support_libs库

cd ~
mkdir ycm_build
cd ycm_build

cmake -G "Unix Makefiles" . ~/.vim_runtime/sources_non_forked/ack.vim/plugged/YouCompleteMe/third_party/ycmd/cpp

wget http://releases.llvm.org/8.0.0/clang+llvm-8.0.0-amd64-unknown-freebsd11.tar.xz
xz -d clang+llvm-8.0.0-amd64-unknown-freebsd11.tar.xz

mkdir -p ~/ycm_temp
tar -xvf clang+llvm-8.0.0-amd64-unknown-freebsd11.tar -C ~/ycm_temp

cd ~/ycm_temp
mv clang+llvm-8.0.0-amd64-unknown-freebsd11 clang_llvm8

cmake -G "Unix Makefiles" -DPATH_TO_LLVM_ROOT=~/ycm_temp/clang_llvm8 . ~/.vim_runtime/sources_non_forked/ack.vim/plugged/YouCompleteMe/third_party/ycmd/cpp

编译
cd ~/ycm_build && make
cd ~/ycm_temp/clang_llvm8 && make
cd ~/.vim_runtime/sources_non_forked/ack.vim/plugged/YouCompleteMe
./install.py --clang-completer

• .ycm_extra_conf.py拷贝到~/下

cp ~/.vim_runtime/sources_non_forked/ack.vim/plugged/YouCompleteMe/third_party/ycmd/.ycm_extra_conf.py ~/.ycm_extra_conf.py

• 配置YCM
  vim ~/.vim_runtime/sources_non_forked/ack.vim/plugged/YouCompleteMe/third_party/ycmd/cpp/ycm/.ycm_extra_conf.py
