clang_complete in Vim

问题

So after playing around with omnicpp, gccsense and clang_complete I couldn't get any of them to work. So I apt-get purge vim-* and tried again to install clang_complete, but without success.

Here's what I do:

1. Download clang_complete.vmb, move it to my fresh, clean .vim dir and execute vim clang_complete.vmb -c 'so %' -c 'q'.

2. Paste this into my .vimrc:

   syntax on
   set number
   filetype plugin on
   let g:clang_user_options='|| exit 0'
   let g:clang_complete_auto = 1
   let g:clang_complete_copen = 1
   

3. Create a typical example

   #include <iostream>
   #include <string>
   
   int main() { std:: (I get: User defined pattern not found) }
   

Is there anything else I need to do/install to get it working? And silly question I've heard about Clang, do I need to apt-get install it?

回答1:

clang_complete can be configured to use the clang executable or the clang library

clang_complete uses the clang executable by default but the clang library will execute lot faster

clang_complete plugin (using the clang executable) needs:

1. clang must be installed in your system and be in the PATH
2. do not set (let) g:clang_library_path to a path containing the libclang.so library

clang_complete plugin (using the clang library) needs:

1. python installed in your system
2. vim must be built with python support (do :version and look for a +python/dyn or +python3/dyn entry)
3. set (let) g:clang_library_path to the directory path where libclang.so is contained

回答2:

let g:clang_library_path='/usr/lib/llvm3.5/lib/libclang.so.1' in my .vimrc and it works fine.
