SOLUTION FOUND :
Minitoc requires for some reason to compile 4 times (and not 2) to implement the changes. Which is why it sometimes didn't work...
I am trying to use the minitoc package to create a minitoc at the beginning of a starred chapter (with starred sections) and I want to change the name of the minitoc from "Contents" to "Procedure".
Here is my code :
\documentclass{memoir}
\usepackage{minitoc}
\dominitoc
\mtcsettitle{minitoc}{Procedures}
\begin{document}
\faketableofcontents
\chapter*{A}
\addstarredchapter{A}
\addcontentsline{toc}{chapter}{A}
\minitoc
\section*{a}
\addcontentsline{toc}{section}{a}
\section*{b}
\addcontentsline{toc}{section}{b}
\end{document}
And I have the following problem :
The minitoc appears when the chapter isn't starred and without modifying the title of the minitoc. Fine !
When I modify the chapter to chapter*, the minitoc appears, but sometimes doesn't (and I cannot figure out what are the difference in the cases, maybe several compilations ?).
When I modify its title (mtcsettitle), the minitoc sometimes appears (same question).
When I do both (chapter* and mtcsettitle), I cannot have the minitoc appear.
Would you have an idea of what goes wrong here ?
