Vim Editor->clang_complete: no python support available

Question

Case: Testing clang_complete with gVim 7.3

I installed MinGW, then followed the tutorial here to download and compile clang. It compiled for around an hour, then make install. Clang worked. I especially love the error annotation. It's amazing.

Now comes the case of clang_complete. I Installed it. I am using pathogen, so clang_complete fron github comes in bundle folder inside vimfiles.

I opened the vim editor and gave command :scriptnames. It shows clang_complete plugin. :version shows it has python entry, so vim was built with python support. Also my test system has python installed.

but whenever I issue :save foo1.cpp , vim give this error,

Error detected while processing function 14_ClangCompleteInit..14_initClangCompletePython: line2 clang_complete:No python support available line 3 cannot use clang library.

simply puzzled.

*I have python installed on my system. I Also tried using libclang library path for clang_complete as mentioned in another question on clang_complete here, but to no avail.*

Thank you.

Vim needs to be compiled with Python support, i.e. +python when doing :version. -python means it's not installed. Taken from clang_complete at Github:

You need Vim 7.3 or higher, compiled with python support and ideally, with the conceal feature.

You said you had this enabled, but it doesn't look like it. Taken from clang_complete.vim.
This is the only place that error message is defined and triggers on !has('python'). In other words this doesn't seem to be a clang_complete issue, but rather that your install is missing or is having problems with Python support.

function! s:initClangCompletePython()
  if !has('python')
    echoe 'clang_complete: No python support available.'
    echoe 'Cannot use clang library'
    echoe 'Compile vim with python support to use libclang'
    return 0
  endif
