Ubuntu 18.04 安装 ycm

参考 YouCompleteMe#installation

下载 Vundle

• git clole https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim

下载 YCM

• git clone git@github.com:ycm-core/YouCompleteMe.git ~/.vim/bundle/YouCompleteMe
• cd ~/.vim/bundle/YouCompleteMe && git submodule update --init --recursive

修改 ~/.vimrc 脚本

编辑 ycm_core 库

• 创建目录用于存放编译过程产生的文件
  • mkdir ~/.ycm_build && cd ~/.ycm_build
• 生成 Makefiles
  • 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
  • 输出如下 ``` – The C compiler identification is GNU 7.5.0 – The CXX compiler identification is GNU 7.5.0 – Check for working C compiler: /usr/bin/cc – Check for working C compiler: /usr/bin/cc – works – Detecting C compiler ABI info – Detecting C compiler ABI info - done – Detecting C compile features – Detecting C compile features - done – Check for working CXX compiler: /usr/bin/c++ – Check for working CXX compiler: /usr/bin/c++ – works – Detecting CXX compiler ABI info – Detecting CXX compiler ABI info - done – Detecting CXX compile features – Detecting CXX compile features - done – Found PythonLibs: /usr/lib/x86_64-linux-gnu/libpython3.6m.so (found suitable version “3.6.9”, minimum required is “3.5”) – Using libclang to provide semantic completion for C/C++/ObjC – Boost version: 1.65.1 – Found the following Boost libraries: – filesystem – regex – system – Using external libclang: /usr/lib/x86_64-linux-gnu/libclang-3.9.so.1 – NOT using clang-tidy for static analysis. – Configuring done – Generating done – Build files have been written to: /home/binli/.vim/ycm_build

  ```

• 构建 ycm_core
  • cmake --build . --target ycm_core --config Release
  • 输出如下

配置

• 复制 .ycm_extra_conf.py 脚本
  • cp ~/.vim/bundle/YouCompleteMe/third_party/ycmd/examples/.ycm_extra_conf.py ~/.vim/
• 添加 vim 配置：在 ~/.vimrc 文件中追加

  1 2	let g:ycm_server_python_interpreter='/usr/bin/python' let g:ycm_global_ycm_extra_conf='~/.vim/.ycm_extra_conf.py'

附：我自己的 ~/.vimrc 脚本
