Hi all,

I've got this warning when compiling:

,----
| Compiling /home/guerry/install/git/org-mode/lisp/ob-R.el...
| 
| In end of data:
| ob-R.el:401:1:Warning: the function `org-every' is not known to be defined.
`----

(There is no org-every in ob-R.el directly.)

And ~$ make test fails like this:

`----

This is with latest Org and Emacs 24.3.50.1, as compiled from trunk
yesterday.

I don't have time to look into this right now, but maybe someone has.

Thanks,

This is caused by the following constructs in test-ob.el:

--8<---------------cut here---------------start------------->8---
(ert-deftest test-org-babel/inline-src_blk-default-results-replace-line-1 ()
  (let ((test-line "src_sh{echo 1}"))
    ;; src_ at bol line 1...
    (org-test-with-temp-text
	test-line
--8<---------------cut here---------------end--------------->8---

ert-deftest is a macro and when it gets expanded the let binding is not
yet established, thus the expansion of test-line fails further down in
the body.  I'm not sure if this is supposed to work or not.  The older
Emacsen just didn't expand the macro at all so the body was interpreted
at runtime, Stefan Monnier made this an error a while back in trunk,
IIRC.  You might ask on emacs-devel for more details.


Regards,
Achim.

Thanks -- I remember we had this issue before.  I'm just surprise I'm
the first one to report it, I assume many people use a recent Emacs
with macro expansion done this way.

Can you ask this on emacs-devel and see what could be done?

Or someone else that grok the issue well?

This patch fixes the error, but it looks strange (indentation is still
unchanged for clarity).  Not sure if this an Ert or Emacs error, though.

I suggest you handle this the way you prefer: either by committing
this in Org before asking emacs-devel@, or by asking first then see
of this needs to be fixed upstream?  I won't have time to digg this
issue further, sorry.

I'll just keep the patch locally for the moment, at least until I've
looked at Ert and/or made a test case that can be reoprted to
emacs-bugs.  If anybody wants to test on Emacs trunk, it is easy enough
to apply the patch, I think.

This turned out to be a bug in Org after all.  Some test macro
definitions weren't quoted correctly, which generally fails hard with
eager macro expansion as macro expansion and macro execution become
really seperated with it.  Fix has been pushed to master.
