Footnote export to LaTeX "wrong number of arguments" error

Footnote export to LaTeX "wrong number of arguments" error

[John Hendy]

I saw the previous post about LaTeX footnotes, but I don't think
that's my issue (seemed to related to sites with underscores in the
URL).

I just upgraded to 7.7 and can't export this simple example:

-----

* section

Let's see what happens. [fn:1]

* Footnotes

[fn:1] somethign to say
-----

I get this error in the minibuffer:

---------
Export buffer:

Any suggestions? I have no idea what's going on...

Neither have I, but your example exports OK for me, so I'd venture to
guess that your install is incomplete or mixed-up between old and new
somehow.  Try a 'make clean' and check where Emacs picks up org-mode.

I just redid make clean followed by make && make doc.

I'm puzzled by this, though:

,---
| M-x org-version
| Org-mode version 7.5 (release_7.7.23.ge5faa)
`---

Is that 7.7 or 7.5 (I don't understand version vs. release)? I just
did a fresh pull this morning, so I figure it should be 7.7. Does this
look right or is emacs looking in the wrong place perhaps? My .emacs
has the following:

,---
| (add-to-list 'load-path "~/.elisp/org.git/contrib/scripts/")
| (add-to-list 'load-path "~/.elisp/org.git/contrib/lisp/")
| (add-to-list 'load-path "~/.elisp/org.git/lisp/")
`---

Anything stick out or suggestions of further checks?

Thanks,
John

Sorry that the other email didn't explicitly state... but that did
*not* fix the issue for me. Same error.

That is strange, it looks like you've been picking up an old version of
org-mode that then finds the git version later on.

> Anything stick out or suggestions of further checks?

It looks like you're trying to use the work tree like an installed
org-mode.  In this case you should do this:

make cleanall
make all autoloads

…otherwise you'll be keeping around a stale copy of org-install.el
(whcih you probably require somewhere in .emacs).

Correct, I don't re-install to the system tree in /usr/share/..., I
just use a local folder in ~/.elisp.

Did that, same issue. It actually said nothing to be done for make all
autoloads. One thing of note, though... the error features this:

,---
| ("/usr/share/emacs/site-lisp/org-footnote.elc" . 6816)], 1
`---

I noted that for some reason it's pulling from /usr/share/emacs.../
and not ~/.elisp/org.git, despite my setting in .emacs. What did I do
wrong in setting that?

Do a M-x locate-library RET org-install RET and see what happens?

What does M-: load-path report?

Grrrrrr. So stupid, but 90% of my problems are, so I guess I shouldn't
be surprised.

Looking back through my .emacs, I *couldn't believe* that I saw
(require 'org-install) *above* my load path settings!! I guess I don't
use org-mode nearly as much at home (this is on my personal computer)
vs. work and it's been like this all along. How crazy.

Now, however, I'm getting the same problem as reported here, except
not when I try to open links, but when I try to export to pdf via
LaTeX:
--- http://www.mail-archive.com/emacs-orgmode@gnu.org/msg44866.html

,---
| Symbol's value as variable is void: org-babel-inline-src-block-regexp
`---

I've done make clean && make && make doc about 10 times today already,
including Achim's suggestion of make cleanall & & make all autoloads.

Why might this be happening?

Thanks again for persisting. Sorry the answer to the original problem
wasn't more satisfying.

1. Does it work after doing make clean?
2. Does it work with release_7.7?

  $ git reset --hard release_7.7

If it works with both 1 & 2 then (may be) Eric's recent checkin is
causing this regression. 

ps: My elisp-fu is quite weak to understand Eric's recent changes.

Surprisingly (to me at least), this does work. The current git tree
after make clean exports fine.

This also works.

I'll respond to the other thread about C-c C-o as well.

Just to be clear, the latter suggestion is only needed if you never use
"make install", which would refresh org-install.el.

>

This does not remove org-install.el when it is already present.  You
must use 'make cleanall' to remove it.

I've tested John's document on the latest Git head that includes this
commit.  I'm getting the feeling that John might have customized the
load-path in more than one place and that add-to-list might not
prepending the entries as he assumes since they are already present in
load-path.  Something like

(setq load-path (cons (expand-file-name "~/.elisp/org.git/lisp") load-path))

should be more robust in this case.

No idea. All I can confirm is that:

- git pull
- make clean && make

behaves differently than:

- git pull
- make clean

Also no idea. I have used the same method for loading paths and never
had a problem before. Let me know what you think of my config here:
http://pastebin.com/ztvgMFFd

Also, I never posted in response to Jambunathan's request:

,---
| M-: load-path
| ("~/.elisp/org.git/lisp/" "~/.elisp/site-lisp/"
"~/.elisp/org.git/contrib/lisp/" "~/.elisp/org.git/contrib/scripts/"

| "/usr/share/emacs/23.3/lisp/org" ...)

Let me know if anything looks awry here.

What is prefix set to in your Makefile?

Looks good.  However I see you're using Emacs23 while I'm using Emacs24,
so I'll try it with the other version tomorrow.

Since it is added to the load-path during compile it might have
undesirable side-effects if an older org-mode resides at that path.

But, I'm now getting these errors too since I have started Emacs
freshly.  The offending commit is 9ff7f80f51a by Eric Schulte, where he
wraps the defvar definition into eval-when-compile.  This change defines
the variable during compile and gets rid of that error, but then it is
not defined when loading org-mode the first time.  If you do an
org-reload this is rectified (which is why I didn't see the error
yesterday.

The original error during compile-time comes from using the variable in
a macro expansion.  I don't think this is the right thing to do since we
would not want to expand the variable at compile time (it would not be
variable anymore after compilation).  The attached patch seems to
correct this for me.

Let us know if that fixes things for you and I'll let Eric decide if he

wanted to do.

Thanks for the checking on this. Yes, M-x org-reload fixes this for
me. No exporting the first time, reload, then successful export the
second time with  no error about the babel variable.

Thanks for all your work,

One of your followup mail says this 

,---
| (add-to-list 'load-path "~/.elisp/org.git/contrib/scripts/")
| (add-to-list 'load-path "~/.elisp/org.git/contrib/lisp/")
| (add-to-list 'load-path "~/.elisp/org.git/lisp/")
`---

This is inconsistent with the last line of the error trace (seen above)

Do M-x locate-library RET org-footnote RET and make sure that nothing is
amiss.
