我正在尝试将 (6) 个 .tex 文档合并为一个文档。尝试了几个“合并”模板，但都没有用。这是我目前的主要文档尝试。
\documentclass[book]{combine}
\title{Pepperdine Papers on LTL}
\author{J. Stanley Warford, David Vega, Scott M. Staley}
\date{today}
\begin{document}
\pagestyle{combine} % use the combine page style
\maketitle % main title
\tableofcontents % main ToC
\clearpage
\section{Editor’s introduction}
Here is where the introduction will be written
\label{Introduction} % into main ToC (section 1)
\begin{papers}
\coltoctitle{A Calculational Deductive System for Linear Temporal Logic}
\coltocauthor{J. Stanley Warford, David Vega, Scott M. Staley}
\label{eds4ltl-paper-copy}
\include{eds4ltl-paper-copy}
\coltoctitle{Vega Paper}
\coltocauthor{J. Stanley Warford, David Vega, Scott M. Staley}
\label{Vega-Paper-copyFontsChanged}
\include{Vega-Paper-copyFontsChanged}
\end{papers}
\clearpage
\section{Acknowledgements}
Here is where the Acknowledgments and Prologue will be written.
\end{document}
这是我当前收到的错误代码：
eds4ltl-paper-copy.tex 9 未定义控制序列。\leqnomode ->\tagsleft@true l.9 \leqnomode
任何帮助都将不胜感激。谢谢
