I am trying to precompile with xelatex so subsequent compilations could be quick. Here is the MWE. This is the file that I will compile to produce the desired output.
%&myone
%xelatex -ini -jobname="one" "&xelatex" mylatexformat.ltx myone.tex
\begin{document}
Hello World!
\end{document}
This is myone.tex:
%xelatex -ini -jobname="myone" "&xelatex" mylatexformat.ltx myone.tex
\documentclass{article}
\begin{document}
\end{document}
When I issue:
xelatex -ini -jobname="myone" "&xelatex" mylatexformat.ltx myone.tex
It produces an error:
! Can't \dump a format with native fonts or font-mappings.
How do I proceed with precompiling?
