我最近将页码改为十二进制（见这里)。makeidx 包根本不喜欢这样。事实上，我的索引根本就不存在了：
已完成 (0 项已接受，341 项已拒绝)。Kyroledorn Yartolikor.ind 中未写任何内容。抄本已写在 Kyroledorn Yartolikor.ilg 中。
更改之前一切都正常，所以这是这里唯一的问题。其他问题暗示 makeidx 对页码的更改有一些限制，但我没有找到解决这个问题的方法。有什么想法吗？
作为代码示例，我在上述问题的代码示例中添加了一个索引，就像我在其他文件中所做的一样。
\documentclass[11pt,a4paper,final]{book}
\usepackage[left=2cm,right=2cm,top=2cm,bottom=2cm]{geometry}
\usepackage{makeidx}
\makeindex
\usepackage{graphicx} % I need this to rotate my numbers...
\usepackage{xparse} % this is the magic package...
\ExplSyntaxOn % for the missing numbers after 9 the package uses "a" and "b",
% but I want to use "↊" and "↋" as defined by the Dozenal
% Society of Great Britain. The following lines do that for me:
\NewDocumentCommand{\basetwelve}{m}
{ \duodec_convert:n { #1 } }
\tl_new:N \l_duodec_string_tl
\cs_new_protected:Npn \duodec_convert:n #1
{
\tl_set:Nx \l_duodec_string_tl { \int_to_base:nn { #1 } { 12 } }
\tl_replace_all:Nnn \l_duodec_string_tl { a } { \rotatebox[origin=c]{180}{2} }
% I rotate the numbers, because standard fonts don't contain ↊ and ↋.
\tl_replace_all:Nnn \l_duodec_string_tl { b } { \rotatebox[origin=c]{180}{3} }
\tl_use:N \l_duodec_string_tl
}
\ExplSyntaxOff
\renewcommand{\thepage}{\basetwelve{\arabic{page}}}
\renewcommand{\thepart}{\basetwelve{\arabic{part}}}
\renewcommand{\thechapter}{\basetwelve{\arabic{chapter}}}
% No problems so far...
% This is how you get numbering formatted as chapter.section:
\renewcommand{\thesection}{\thechapter.\basetwelve{\arabic{section}}}
\renewcommand{\thesubsection}{\thesection.\basetwelve{\arabic{subsection}}}
% Dont put \thechapter here, it is already contained in \thesection!!!
\renewcommand{\thefigure}{\basetwelve{\arabic{figure}}}
% As I told you, I wanted to change the figcaptions too.
% But I don't need the chapter's number here.
\renewcommand{\labelenumi}{\basetwelve{\arabic{enumi}}.}
% And this is my first dozenal enumeration with a dot behind the number.
%let's see, if it works:
\begin{document}
\part{Quick demonstration}
\chapter{Here we go!}
Just scroll down...
\chapter{I}
\chapter{need}
\chapter{lots}
Whoops, nearly there...
\newpage
On this and on the following page you see the dozenal page numbers! \index{dozenal page number}
\chapter{of}
See? It works! \index{working!}
\chapter{pages}
\chapter{and}
\chapter{chapters}
\chapter{for}
\chapter{dozenal}
This is the dozenal number \rotatebox[origin=c]{180}{2}, equal to $ 10_{(10)} $.
\chapter{numbers.}
This is the second dozenal number: \rotatebox[origin=c]{180}{3}, it is just a turned 3 and equal to $ 11_{(10)} $.
\section{What are these symbols?!}
I use fonts like Times New Roman, they have symbols \index{symbols} like \rotatebox[origin=c]{180}{2} and \rotatebox[origin=c]{180}{3} integrated as Unicode glyphs U+218A and U+218B. They are just rotated numbers too, basicly. These numbers are defined by the Dozenal Society of Great Britain and I like them. If you complie with XeLaTeX you can just copy and paste these signs: ↊ and ↋ (in this font they will probably be invisible).
\section{Why so many chapters?}
I need more than 12 pages and chapters for the numbers \index{numbers} \rotatebox[origin=c]{180}{2} and \rotatebox[origin=c]{180}{3} to appear.
\section{Enumeration}
\begin{enumerate}
\item Just
\item a
\item very
\item short
\item demonstration
\item of
\item a
\item dozenal
\item enumeration
\item for
\item you
\item to
\item admire.
\end{enumerate}
\section{Just a random section}
\subsection{with a subsection}
\subsubsection{and a subsubsection}
These all work just finde with dozenal numbers aswell but I think the code is already long enough. And as you see, subsubsections usually don't have numbers at all.
\printindex
