Clang plugin issue

I have installed the plugin clang_complete. I put these settings in my .vimrc:

   let g:clang_use_library      = 1
   let g:clang_auto_select      = 0
   let g:clang_complete_auto    = 1
   let g:clang_complete_copen   = 1
   let g:clang_complete_macros  = 1
   let g:clang_complete_patters = 1
   set completeopt=menu,longest

   let g:clang_library_path = '/usr/lib/clang'
   "let g:clang_library_path = '/usr/lib/llvm-2.9'

   let g:clang_auto_user_options = "-I/usr/include/c++/4.6, .clang_complete"
   let g:clang_snippets = 1
   let g:clang_snippets_engine = 'clang_complete'

Every time when I open the .cpp file I have got the following error message:

Error detected while processing function <SNR>15_ClangCompleteInit..LoadUserOptions:
line   20:
E121: Undefined variable: getopts#
Loading libclang failed, falling back to clang executable.  Are you sure '/usr/bin/clang' contains libclang?

vim is compiled with the python feature. So vim --version is gets:

Can anybody help to resolve the problem?

You have two problems here.

  1. The value you give for g:clang_auto_user_options is invalid. The "path" that the clang_complete documentation mentions doesn't mean that a path should be written in the option string; it refers to using Vim's built-in 'path' option to provide the list of -I flags.

    Use set g:clang_user_options = "-I/usr/include/c++/4.6" instead, which just gets passed straight through to clang.

    Aside: The getopts# in the error occurs because clang_complete tries to interpret your -I... string as a part of the name of an options-source function. (The {anything} clause in the docs.) The - in getopts#-I/usr/include/c++/4.6#getops() isn't a valid Vimscript function character so it gets truncated there.

  2. clang_complete expects the g:clang_library_path directory you specify to contain the libclang.dylib or libclang.so directly inside of it (e.g. /usr/lib/clang/libclang.so in your case).

    Not all distributions of clang provide the libclang shared library, so you might need to compile it yourself.
