Hi,

I am trying to tangle a file in batch mode using the script bellow:

emacs.exe  -Q --batch --no-init-file -l init.el --visit file.org -f
org-babel-tangle --kill

== init.el ===

(require 'org)
(require 'org-exp)
(require 'ob)
(require 'ob-tangle)
(require 'ob-R)

(org-babel-do-load-languages
 'org-babel-load-languages
 '((R . t)
   (latex . t)
   (sh . t)
   (plantuml . t)
   (emacs-lisp . t)
   ))

;; For windows
(setq org-babel-R-command
"\"C:/Users/XX/Documents/R/R3.2.0/bin/i386/Rterm.exe --ess --slave
--no-save\"")

== end file ==

And

== file.org ==

-*- mode: org; mode: auto-fill; fill-column: 76 -*-

# Babel settings
#+PROPERTY: session *R*
#+PROPERTY: comments yes
#+PROPERTY: results output
#+PROPERTY: exports none


* Simple babel block

#+name: setup_block
#+begin_src R :tangle Rcode/setup_block.R :exports none :session

  proj.dir <- getwd()
  cat("Proj dir: ", proj.dir,"\n")

#+end_src

== end file ==

When I set #+PROPERTY: comments no, I am able to tangle the file file.org.
However when I set  #+PROPERTY: comments yes I have got this message:

No comment syntax is defined.  Use:

If I just press enter I end up with the error code:

<<<<<<
No comment syntax defined
make: *** [tangle] Error 127
>>>>

The file I want to tangle is a large file with a lot of org-babel blocks. I
understand that the comment is not defined, but I don't know how to set it.

I am running emacs on windows:
GNU Emacs 24.3.1 (i386-mingw-nt6.1.7601)
Org-mode version 8.3.1

Anyone can help me with that?

Thanks,
