org --> odt with math

org --> odt with math

[Uwe Brauer]

Hi

Using org (git version) GNU emacs 26 on Ubuntu 14.04,
following
http://orgmode.org/manual/Working-with-LaTeX-math-snippets.html#fn-2
I have set
(setq org-latex-to-mathml-convert-command
                "/usr/bin/latexmlmath \"%i\" --presentationmathml=%o")

Latexmlmath is installed of course.

I try to convert the following file to odt with mathml
#+OPTIONS: LaTeX:t

This 
\begin{equation}
\label{eq:aned-ex:1}
\begin{cases}
  y^{\prime}&= -2000(y-\cos(t))\\
   y_0&=0 \qquad 0\leq t \leq 1.5
 \end{cases}
\end{equation}

But the equation is just exported as ASCII code. What do I miss?

Regards

Uwe Brauer

    -  I exported it via org-export-dispatch and then I chose odt.

    -  then I tried org-odt-export-as-odf and obtained

Using vacuous schema
Wrote /tmp/odf-2719bZW/ltxmathml-in2719ojc
Running /usr/bin/latexmlmath "" --presentationmathml=ltxmathml-out27191ti
LaTeX to MathML conversion failed
XPath error : Undefined namespace prefix
 error : xmlXPathCompiledEval: evaluation failed at /usr/share/perl5/LaTeXML/Common/XML.pm line 326.

OpenDocument export failed: No Math formula created
Updating buffer list...done

This is bad, but I am not sure who is the culprit here.

There is no such thing.

It is #+options: tex:t

I think that happens when there’s an error.

Do you see the help message when you run latexmlmath from the commandline?

Perhaps you need to load some modules manually?  See the latexml manual

    http://dlmf.nist.gov/LaTeXML/manual.pdf

Can latexml create a proper mathml version if you provide a "full" latex
file with the equation and the right packages?
