which version for python and clang

[lougxing]

MY system is centos6.2
My vim version is 8.2(+python3/dyn +python/dyn)
libclang.so is 3.4
python is 2.6.6
python3 is 3.4.5

bash-4.1$ cat .vimrc
let g:clang_library_path='/usr/lib64/llvm/libclang.so'
let g:clang_complete_copen=1
let g:clang_periodic_quickfix=1
let g:clang_snippets=1
let g:clang_close_preview=1
bash-4.1$ ll /usr/lib64/llvm/libclang.so
-rwxr-xr-x 1 root root 14477112 Jan 3 2015 /usr/lib64/llvm/libclang.so

The error message "Option completefunc is not set"

Try with

let g:clang_library_path='/usr/lib64/llvm/'

This option specifies directory.

It still didn't work.

bash-4.1$ cat .vimrc
let g:clang_library_path='/usr/lib64/llvm/'
let g:clang_complete_copen=1
let g:clang_periodic_quickfix=1
let g:clang_snippets=1
let g:clang_close_preview=1

bash-4.1$ rpm -qf /usr/lib64/llvm/libclang.so
clang-3.4.2-4.el6.x86_64

bash-4.1$ cat .clang_complete
-I/usr/include/c++/4.4.4/

bash-4.1$ cat a.cc
#include
#include

int main() {
std::vector mm;

}

bash-4.1$ ll /usr/include/c++/4.4.4/vector
-rw-r--r-- 1 root root 2698 Jun 19 2018 /usr/include/c++/4.4.4/vector

Right, looks like clang_library_path can point to a directory as well. I forgot about it.
