When I try to set the table offered in the manual of reledmac, I get the error: "undefined control sequence \reserved\c -> l@d@index", which definetly is a problem of the \edindex. Normal \index works. What am I doing wrong?
MWE:
\documentclass{scrbook}
\usepackage{imakeidx}
\usepackage{reledmac}
\makeindex
\begin{document}
\beginnumbering
\pstart
\begin{edtabularl}
\textbf{\Large I} & wish I was a little bug\edindex{bug} &
\textbf{\Large I} & eat my peas with honey\index{honey} \\
& With whiskers \edtext{round}{\Afootnote{around}} my tummy &
& I've done it all my life. \\
& I'd climb into a honey\index{honey} pot &
& It makes the peas taste funny \\
& And get my tummy gummy.\index{gummy} &
& But it keeps them on the knife.
\end{edtabularl}
\pend
\endnumbering
\end{document}
