当我编译以下示例时：
\documentclass[11pt,a4paper,oneside]{book}
\usepackage{caption}
\captionsetup{margin=10pt,font=small,labelfont=bf}
\usepackage[pdftex]{hyperref}
\begin{document}
text
\end{document}
我收到“包标题警告”。最终输出看起来不错，我只是好奇这个警告是什么意思以及如何消除它。
@Martin：\listfiles 给了我这个

也许该问题是由 6.80x 版本的 hyperref 引起的？
答案1
我联系了 caption 的作者 Axel Sommerfeldt，询问了去年 hyperref v6.79l 中出现的不兼容性问题。Axel 于 1 月发布了 caption 版本 3.1l，解决了这个问题。
答案2
也许您使用的是旧版本的 caption 或 hyperref？编译您的示例时我没有收到任何警告。尝试添加 \listfiles 并与我的系统上运行的文件列表进行比较。
附注：如果您在 pdf 模式下使用 pdftex，则无需为 hyperref 指定 pdftex 驱动程序。
