You're more lucky than I am ;-)

`M-x version' gives: "Org-mode version 6.32trans". I think I got it on last
Thu or Fri morning.

I have, since long, the following chunk in my `.emacs', for setting the

--8<---------------cut here---------------start------------->8---
;; change the default directory (if it exists)
;; (it is also the default directory when attaching files to mails)
(let ((my-default-directory "~/"))
  (setq default-directory
        (if (file-directory-p my-default-directory)
          (getenv "HOME"))))
--8<---------------cut here---------------end--------------->8---

When looking for the current value of that variable, I have:

--8<---------------cut here---------------start------------->8---
default-directory is a variable defined in `C source code'.
Its value is "~/"
Local in buffer *followup to Bernt Hansen on gmane.emacs.orgmode*; global value 
is nil

  Automatically becomes buffer-local when set in any fashion.
  This variable is safe as a file local variable if its value
  satisfies the predicate `stringp'.

Name of default directory of current buffer.  Should end with slash.
To interactively change the default directory, use command `cd'.
--8<---------------cut here---------------end--------------->8---

Note that I am a bit puzzled, now, by the fact that variable has a
buffer-local value, and that its global value is nil. Maybe I should do
`setq-default' instead of `setq'?

Anyway, I don't remember exactly why I did set that, but I think it's for easy
opening of files (right prefix when `C-x C-f').

Regarding my Org files, I have 2 main usages:

- organizational files, with items to do, scheduling dates and deadlines;
- text files (without any active dates) that I purely want to write easily and
  export nicely (in LaTeX).

The "organizational files" are located either in `~/Personal' or in

--8<---------------cut here---------------start------------->8---
    ;; directory with org files (used by the hooks for `remember.el')
    (setq org-directory
          (if (file-directory-p "~/Personal/")

    ;; set which files to search for TODO entries and scheduled items
    ;; (avoiding hidden files)
    (setq org-agenda-files
          (append (directory-files org-directory t "^[^\\.].*\\.org$")
                  (if (file-exists-p "~/Projects/")
                      (directory-files "~/Projects/" t "^[^\\.].*\\.org$")
--8<---------------cut here---------------end--------------->8---

The "text files" are anywhere on my disk, generally in subdirectories of

The real directory of the file that's causing me "troubles" (in my above
description) is, for example,

I'm exporting with `C-c C-e l' to produce a LaTeX document in another buffer.
Then, I move to it, and do `C-c C-c' to compile it to PDF, and view it.

Carsten, you pinpoint another trouble that I've had months ago (when first
using Org) and never changed, being accustomed to it, over time...

If I do `C-c C-e d', I never get the PDF successfully compiled, as TeX says it
does not find my pictures (though, local to the document).

My document is here:


My static picture (for direct inclusion, not generated by Ditaa) is there as


And the created files (when `C-c C-e d') are there:

- ~/Projects/Insurance/Acme/docs/operations-manual/Upload_documentation.tex
- ~/Upload_documentation.aux
- ~/Upload_documentation.idx
- ~/Upload_documentation.log
- ~/Upload_documentation.out
- ~/Upload_documentation.pdf
- ~/Upload_documentation.toc
- ~/procedure.png

So, the TeX file is correctly located, but the auxiliary ones not.

And TeX fails to produce the PDF with the following error:

--8<---------------cut here---------------start------------->8---
LaTeX Warning: File `cygwin-icon.png' not found on input line 153.

! Package pdftex.def Error: File `cygwin-icon.png' not found.
--8<---------------cut here---------------end--------------->8---

Maybe it's completely related to the above problem?

Best regards and many thanks for your help,

Sébastien Vauban
