内容超过两页时出现问题

当目录超过两页时，我收到此警告：

具有相同标识符 (name{page.i}) 的目标已被使用，忽略重复 \relax l.36 ...on}{\numberline {5.6}test}{9}{section.5.6} [1])pdfTeX 警告 (ext4): d

如果文档不太长，我们就不会收到警告，例如：

\documentclass[a4paper]{memoir}




\title{Test}
\usepackage{hyperref}

\begin{document}

\frontmatter
\begin{titlingpage}
    \maketitle
    \end{titlingpage}

\tableofcontents


\mainmatter
\chapter{test}
\section{test}

\end{document}

但是，如果我们增加文档以致内容超过几页，我们就会收到警告，给出警告的文档示例如下：

\documentclass[a4paper]{memoir}




\title{Test}
\usepackage{hyperref}

\begin{document}

\frontmatter

有没有办法来解决这个问题？

答案1

造成错误的主要原因是titlingpage环境，它明确地用重置了页码\setcounter{page}{\@ne}——这会混淆设置的超锚点hyperref。

在类似的答案中，我跟踪了此类页码更改（请参阅https://tex.stackexchange.com/a/355883/31729)，在这里我使用了同样的方法，但根据titlingpage环境进行了调整，通过修补\mem@titlingpage及其“朋友” \endmem@titlingpage。

最后，只要没有\setcounter{page}发生其他明确的操作，这将消除警告并提供正确的超锚点。

另一个可能的解决方案（但未经测试）：使用或 中的hypertexnames=false选项。hyperref\hypersetup

\documentclass[a4paper]{memoir}


\usepackage{xpatch}

\newcounter{pagenumberingcalls}
\newcommand{\pagenumberingchanges}{\thepagenumberingcalls}

\makeatletter

\AtBeginDocument{%
  \xpretocmd{\pagenumbering}{\edef\@previouspagenumberingcalls{\thepagenumberingcalls}\stepcounter{pagenumberingcalls}}{}{}

答案2

要消除警告，您只需在前两页中使用合适的 来欺骗 hyperref 即可\pagenumbering。任何不同于arabic和roman的东西都在之后使用。

\documentclass[a4paper]{memoir}

\title{Test}
\usepackage{hyperref}

\begin{document}

\frontmatter
\pagenumbering{Roman}

\begin{titlingpage}
    \maketitle
\end{titlingpage}

\pagenumbering{roman}
