mk4ht oolatex tester.tex
I get:System return: 0
System call: mv sxw-tester.dir/tester.odt .
mv: cannot stat 'sxw-tester.dir/tester.odt': No such file or directory
--- Warning --- System return: 256
I have used this approach many years ago, but on Xubuntu 21.10 it ain't working at all. And my latex file is as easy as can be:\documentclass[12pt]{article}
\pagestyle{empty}
\begin{document}
\section{TEST 1}
testing
\end{document}
