I've originally sent my reply only to OP, so here it is again. Sorry
for the noise.


I get the same error as you with this TeX file, so the issue is not
caused by a wrong installation of teX4ebook or make4ht. I've found
that the fatal error is caused by this line at the beginning of the TeX


As TeX4ht works in the DVI mode, this causes everything to fail. I don't
think that it has any meaning, so I would remove it. If it has some use,
you can disable it just for TeX4ht, using:


With this change, I can compile the file. There are still problems
though. One seems to be caused by a wrong configuration for eqnarray,
the other is caused by \maketitle redefinition in the custom package.

Here is the mycfg.cfg file, it should fix these issues:

     {\ifvmode\IgnorePar\fi\EndP\HCode{<div class="eqnarray">}}

% fix clash with \maketitle
% close <div> before \tableofcontents
% put \title in <h1> element
% disable \hrule
\special{t4ht at _}

Compile the document using:

tex4ebook -c mycfg.cfg -f epub3+dvisvgm_hashes draft

I've used the `dvisvgm_hashes` extension. It requires the SVG output for
math and included PDF images. It is also faster, as it converts several
images at once.

Best regards,

So I just copy the source code of make4ht and luaxml to tex4ebook, and untar the arxiv source in tex4ebook. This is not elegant, but it's what I could finish for now. For texlive, mk4ht, htlatex I installed them by sudo apt-get.
