编译构建ycm_core库

cd ~/downloads/
mkdir ycm_build
cd ycm_build
cmake -G "Unix Makefiles" -DUSE_SYSTEM_BOOST=ON -DPATH_TO_LLVM_ROOT=~/downloads/clang+llvm/ .
 ~/.vim/bundle/YouCompleteMe/third_party/ycmd/cpp
cmake --build . --target ycm_core

编译YouCompleteMe

$ cd   ~/.vim/bundle/YouCompleteMe/

$ ./install.sh  --clang-completer

cd ~.vim/plugged/YouCompleteMe (vim)
cd ~/.local/share/nvim/site/plugged/YouCompleteMe (neovim) :)
