I've a bit of a weird question. I would like to put an equation in the section title (I'm using book) but LaTex spits out the following error:

    [31] [32]Making bbold25.tfm from C:\Users\unknown\AppData\Local\MiKTeX\2.9\fonts\source\jknappen\sauter\bbold25.mf...

l.2280 \chapter{The $beta$}

? 

I've tried to debug and found that there is no problem with my setup (packages, etc.) because I can use equation in titles when I've deleted all my previous chapters. Subsequently, I tried deleting each chapter one at the time to determine what chapter causes the problem and, weirdly, it turns out that all the chapters are not compatible with my section. So in other words, I can put equations in titles if I start a new document, but for some reason it doesn't work with my existing dissertation.

I would also like to mention that the error printed above is mentioning MiKTex, which I have installed on my computer, but I'm using TeXworks because I like it more. This may have something to do with the problem? If anybody could help me with this problem then that would be great.

Best regards,

Edit to show the code that is not working:

\documentclass[10pt,twoside]{book}


\begin{document}

\chapter{Blabla}

\begin{equation}
e^{i 2 \pi \mathcal{N}}=\mathbb{1} \Rightarrow \mathcal{N}=n' \;,\; n' \in \mathbb{Z}
\end{equation}

\section{The $\beta$}


\end{document}

At the moment that I would delete the equation above, then it does work.

Also, this code does work:

\begin{document}

\chapter{Blabla}

\begin{equation}
e^{i 2 \pi \mathcal{N}}= \Rightarrow \mathcal{N}=n' \;,\; n' \in 
\end{equation}

\section{The $\beta$}

\end{document}

So it seems to be related to the \mathbb syntex.

  • The first error is the relevant one here, and this is ! I can't find file b-bbold'. Is seems that you are \inputing a file not installed in your system. Commented Jul 14, 2013 at 0:04

    Your code is missing the amssymb package (for \mathbb). Load it: \usepackage{amssymb}. Does the error persist? Commented Jul 14, 2013 at 0:30

    @Hunter: You have forgotten to load package bbold: \usepackage{bbold}. And MiKTeX package bbold-type1 should be installed to avoid bitmap fonts. Commented Jul 14, 2013 at 0:56

    @Hunter: That's a different package, \mathbbm is provided by package bbm. And in TeX Live I get a bitmap font (bbm10.600pk). Vector fonts (Type 1, ...) are preferred for PDF. Commented Jul 14, 2013 at 5:02

    This question appears to be off-topic because the examples shown don't possibly match the error message.
