The issue is the fact that, when exporting to PDF, in some cases, Org tells

As an example, if you open the target PDF file with Adobe Reader and, in the
meantime, you export your Org file again to PDF, you'll see that Org will tell
you it's OK (Process Completed) while, if you look at the *Org PDF LaTeX
Output* buffer, you'll see an error such as:
! I can't write on file `toto.pdf'.
[...]
The problem comes from the fact that Org just checks for a couple of error
messages (defined in org-latex-known-errors) and report it's OK if it doesn't
find those messages:
Errors are not related to your problem. Actually, "ox-latex.el" uses
a rather weak check to know if process was successful or not:
(if (not (file-exists-p pdffile))
(error (concat (format "PDF file %s wasn't produced" pdffile)
(when errors (concat ": " errors))))
...
(message (concat "Process completed"
(if (not errors) "." (concat " with errors: " errors)))))
First, I have subsequent messages in this thread and the discussion.
Should Nick's observation, that
IOW, it cannot tell the difference between a successful export and an
export failure with an already existing PDF
also include the qualification that the existing PDF file is also opened
at the time of the second export? I base this on Francesco's example
above and the following.
I usually export a subtree to LaTeX as PDF file and open. If I make
small corrections to the subtree and export again, AND forget to close
the PDF file that is already opened from the earlier export, Org reports
a successful export; however, the "revised" exported PDF does not exist.
(Also I use EXPORT_FILE_NAME: in PROPERTIES as the top of the subtree.)
If I remember to close the first exported PDF, the revised subtree
exports OK.
I'm just curious, does the problem exist iff the pdf, that is to be
replaced, is opened?
