Tried putting a 'first headline' as it wants?
ie
* Dummy header
#+BEGIN_SRC emacs-lisp
(defun org-xor (a b)
etc

Hi,

Please include the actual error, as well as a minimal Org-mode file
sufficient to generate the error.  The email below does not contain
enough information to diagnose your problem.

Thanks -- Eric

Oh,

I missed the first message in this thread and didn't realize that the
previous message was a response to an existing bug report (one which
*did* include an error message and reproduction information).

My Apologies for the harsh reply -- Eric

also, I think the original message indicates a bug in Babel's tangling
which I will take a look at.

I've fixed this problem with the attached patch.

I'll push this patch up to the repository as soon as repo.or.cz comes
back online (looks like it's been down for the last couple of hours)

with the patch applied the following will now tangle
--8<---------------cut here---------------start------------->8---
#+begin_src emacs-lisp :tangle yes
  (message "is a problem?")
#+end_src
--8<---------------cut here---------------end--------------->8---

Best -- Eric

[babel] Error Before first headline.

[Olle Palmius]

[-- Attachment #1.1: Type: text/plain, Size: 885 bytes --]

Hi im trying to figure out how to generate sourcefiles from babel
files and i keep getting the same error.
I have tried a few different codeblocks from the documentation
and the only thing that changes is the "position" number.
I hope i have not missed something in the documentation.


Code:

#+BEGIN_SRC emacs-lisp
(defun org-xor (a b)
 "Exclusive or."
(if a (not b) b))
#+END_SRC


Debug message:

Debugger entered--Lisp error: (error "Before first headline at
position 1 in buffer test.org")
  signal(error ("Before first headline at position 1 in buffer
test.org"))
  error("Before first headline at position %d in buffer %s" 1
#<buffer test.org>)
  byte-code("\300\301`p#\207" [error "Before first headline at
position %d in buffer %s"] 4)
  org-back-to-heading(t)
  org-heading-components()
  byte-code("\306\307 !\210p\x10eb\210\310 \311\312#\203\370
