I'm trying to use org-ref to reference to equation numbers. It works with PDF export but never works in HTML export. In the web page it only shows a clickable (???) link with no destination.

I tried in various ways, using \label{·}, #+label: ·, <<·>>, #+name: ·, but I never get numbering in the HTML when using \eqref{·} or eqref:·.

I get an ineffective numbering using [[·]], as the number is always 1; although the link in the HTML points to the correct ID, clicking doesn't lead anywhere.

Is there any way to make it work as expected?

  • I'm getting a better picture of the problem. Equations formatted in the form \begin{equation} \label{·} correctly get referenced with eqref:·. I'm getting problems with equations that have a split block inside. – Mariano M. Apr 15 '20 at 11:40

The issue is related to a bug in MathJax: see https://github.com/mathjax/MathJax/issues/1020#issuecomment-71666257

There is a workaround for this: place \label{·} after \end{split} and before \end{equation}.
