xmlto pdf fails (Fedora)

[spotrh]

This bug has been open in Fedora for several years (see: https://bugzilla.redhat.com/show_bug.cgi?id=949087). Here's how to reproduce it:

1. Take mini.xml:

<?xml version="1.0" encoding="UTF-8"?>
 <book xml:id="simple_book" xmlns="http://docbook.org/ns/docbook" version="5.0">
   <title>Very simple book</title>
   <chapter xml:id="chapter_1">
     <title>Chapter 1</title>
     <para>Hello world!</para>
     <para>I hope that your day is proceeding <emphasis>splendidly</emphasis>!</para>
   </chapter>
   <chapter xml:id="chapter_2">
     <title>Chapter 2</title>
     <para>Hello again, world!</para>
   </chapter>
 </book>

2. Run: xmlto --skip-validation pdf mini.xml

3. Watch it fail:

Other data points: xmlto --skip-validation --with-fop pdf mini.xml works fine.

In the Fedora bug report, it was noticed that commenting out lines 451-456 from epstopdf-base.sty works around this problem, but I am not sure that this fix is valid:

%% \ifETE@prepend
%%   \expandafter\PrependGraphicsExtensions
%% \else
%%   \expandafter\AppendGraphicsExtensions
%% \fi
%% {.eps}

that's odd your log shows grfext.sty being loaded, and all that does is define the command that you show as being undefined on the next line...... If I try

\documentclass{article}
\usepackage{epstopdf-base}
\begin{document}

\show\AppendGraphicsExtensions

\end{document}

then \AppendGraphicsExtensions is shown as defined.

I don't have the xmlto script, could you add the generated tex from the xml, and I'll debug...

[spotrh]

It doesn't seem like xmlto ever spits out the generated tex in a sane way. I've attached the log that it does generate when I run it with "--noclean". tmp.log

[davidcarlisle]

oh! xmltex:-)

OK so it never writes out normal tex syntax it gets tex to read the xml directly (using a parser I wrote in my youth:(

I'd never recommend xmltex these days but I'll see if I can recreate the issue.

if you can give me the xsl FO XML file that is generated and given to tex that would help, as I could run passivetex on that but do't worry if not, I can probably find a copy of xmlto to test...

tmp.fo.txt I had to rename it so that it would attach.
