Bug: ODT export fails if NAME: and ref: equation [9.1.14 (9.1.14-1-g4931fc-elpa @ /home/kdm/.emacs.d/elpa/org-20180910/)]

Bug: ODT export fails if NAME: and ref: equation [9.1.14 (9.1.14-1-g4931fc-elpa @ /home/kdm/.emacs.d/elpa/org-20180910/)]

[Ken Mankoff]

Sorry if this is a triplicate bug report. I emailed this as a message (not bug report) to the Org list a week ago, but have seen no reply. I tried an official bug report last night which I *think* did not work (mailing from within "emacs -Q" does not "just work"), so here I try again.

If I have the following simple Org file, latest Org, and a clean emacs session (emacs -Q), ODT export fails. 

# ====== BEGIN MWE ========
#+NAME: eq:foo
\begin{equation}
42
\end{equation}
See [[eq:foo]].
# ====== END MWE ========

It does not fail if I comment out either of the #+NAME or the "[[eq:foo]]" lines. Note, perhaps tangentially related, that the manual shows "#+LABEL: ", but I'm using "+#NAME: ", and I thought LABEL was deprecated for NAME

No wonder no one answered this; there is nothing simple in "ox-odt.el".

What would be the expected output?

There is no output. It doesn't even export. It's a showstopper. No
references to equations allowed or the exporter fails.

I know. I can reproduce your problem. But I know nothing about ODT, so
it would help if you could tell me what should be the desired output. At
the moment, referencing anything else than a headline or a target is
unsupported in this back-end, AFAICT.

FWIW, the original example works for me if I set
'org-latex-to-mathml-convert-command' to
"latexmlmath \"%i\" --presentationmathml=%o"

as described at
<https://www.gnu.org/software/emacs/manual/html_node/org/Working-with-LaTeX-math-snippets.html#Working-with-LaTeX-math-snippets>

(interestingly I didnʼt have to set #+OPTIONS: LaTeX:t)

Hi Nicolas,

I'd like to see a reference of some sort to the equation. The text should
read "See (1)" or "See Equation (1)". BUT, perhaps this bug, like most, was
operator error on my part.

Without setting up MathML the equation exported as raw LaTeX into the ODT
file. This was fine for me. I saw:

\begin{equation}
42
\end{equation}

 I think that ODT does not view this as an actual equation, so the
[[eq:foo]] label could not be resolved.

Thanks to the hint from Robert Pluim I have it working now. Unlike his
solution, setting `org-latex-mathml-convert-command` did not solve it for
me, but properly setting `org-latex-to-mathml-convert-command` as per
https://www.gnu.org/software/emacs/manual/html_node/org/Working-with-LaTeX-math-snippets.html#Working-with-LaTeX-math-snippets
did work for me. Now the equation appears properly formatted, not as LaTeX,
*and* the reference works.

Thank you (and Robert) for your help with this,

   -k.
