# How create multiple indices with imakeidx?

The following source file was shown in: How to create multiple indices with imakeidx?

\documentclass{scrartcl}

\usepackage[splitindex]{imakeidx}
\makeindex
\makeindex[name=foo,title=Test]

\begin{document}
Test1\index{Test1}
Test2\index[foo]{Test2}
\newpage
Test3\index{Test3}
Test4\index[foo]{Test4}

\printindex
\printindex[foo]
\end{document}


That question was closed because, allegedly, an error in imakeidx was fixed.

However, when I process that source file by running pdflatex (twice, to be sure), then makeindex, and finally pdflatex again, I get no index whatsoever. In fact, there is a single .ind file, and that file is empty.

What am I doing wrong.

• Remove the splitindex option or run pdflatex with the -shell-escape option. – egreg Jul 31 '16 at 20:25

You get a warning:

Package imakeidx Warning: Remember to run (pdf)latex again after calling
(imakeidx)                splitindex' and processing the indices.


which tells you exactly what you need to do.

Alternatively, run pdflatex with the -shell-escape option.

Explanation: splitindex is not in the “list of safe programs” allowed to be called from the restricted shell escape.

Another possibility, with just two indices, is to remove the splitindex` option.
