Tex4ebook not generating SVG files

Question

I followed the instructions in this other question to generate an ePub from Latex with SVG images(I don't want to use ePub 3.0) with tex4ebook, but the generated epub has no images.

I already found this question and I have the package dvisvgm. But I still have the same problem.

This is my .tex file:

\documentclass{book}
\usepackage{mathtools,amsmath,mathrsfs}
\usepackage{amsthm}
\title{Calculus}
\author{Anon}
\begin{document}
\maketitle
\chapter{Chapter title} 
Expression: $\int x^2  dx$
\end{document}

The configuration file, myconfig.cfg:

\Preamble{xhtml,pic-align,pic-m,}
  \Configure{Picture}{.svg}  
  \makeatletter
  \Configure{graphics*}
  {svg}
  {
    {\Configure{Needs}{File: \Gin@base.svg}\Needs{}}
    \Picture[\csname a:GraphicsAlt\endcsname]{\csname Gin@base\endcsname.svg
            \csname a:Gin-dim\endcsname}
  }
  \begin{document}
  \EndPreamble

And I've tried with and without the .mk4 file mentioned in the previous question but I get the same result.

I use the command tex4ebook -c myconfig.cfg tex4htExample.tex

This is the .log file and the terminal output. I can't find the missing package or error.

Edit:

Installed Ubuntu on a virtual machine and installed Texlive with sudo apt-get install texlive-full and I installed tex4ebook. I ran the same command and I had no errors, but the result still has not any SVG file. I've opened the ePub in iBooks, Sigil and Adobe Digital Editions and all of them shows no image(or non existing image) where the expression is supposed to be.

This are the files after calling tex4ebook:

content.opf            tex4htExample.css   tex4htExample.log
efficient.mk4          tex4htExample.dvi   tex4htExample.ncx
myconfig.cfg           tex4htExample-epub  tex4htExample.tex
tex4htExample.4ct      tex4htExample.epub  tex4htExample.tex~
tex4htExample.4tc      tex4htExample.html  tex4htExample.tmp
tex4htExample.aux      tex4htExample.idv   tex4htExample.xref
tex4htExamplech1.html  tex4htExample.lg    zztex4htExample.ps

In the source code of the epub I can see it's trying to print the image tex4htExample0x.svg, but this doesn't exists.

If I run the command saving the output like this:

tex4ebook -c myconfig.cfg tex4htExample.tex > linuxterminal.log

On Linux, I get this output on the screen but not in linuxterminal.log:

I actually have no idea if this is relevant. Trying to find some clue.

And, just in case, the terminal output.

Answer 1

I've got some errors related to graphicx package when I executed your sample. It happened because some internal graphicx macros are used in the .cfg file. Inclusion of graphicx package helped.

The modified file looks like:

\documentclass{book}
\usepackage{mathtools,amsmath,mathrsfs}
\usepackage{graphicx}
\usepackage{amsthm}
\title{Calculus}
\author{Anon}
\begin{document}
\maketitle
\chapter{Chapter title} 

Expression: $\int x^2  dx$
\end{document}

note also blank line after \chapter, for some reason paragraph wasn't created here, which resulted in non-valid e-pub file. So we make explicit paragraph here.

Using the .mk4 file from the linked question, I've got correct result:
