Introduction

\section{Layout}
Write here my text

\begin{center}
\includegraphics[scale=0.5]{Layout.jpg}
\caption{This is the caption of the figure}
\end{center}


The problem is that I was trying to add a caption to my figure, before doing it the main was compiling without problems, but as soon as I put \caption it returns me some errors. In particular in the main I have:

I can't write on file 'Chapters/Introduction.aux'\include{Chapters/Introduction}
Emergency stop \include{Chapters/Introduction}


Which I really can't understand since I haven't changed the Introduction.

And then in the Chapter1 I have this error:

Undefined control sequence \section


If I remove \caption everything returns to work well.

In addition, I would like to know if there is a way to automatically add the figure in the List of Figure.

Can someone help me, please? Thanks.

• You can't use \caption outside of a float (figure or table that is). Either use one of the floating environments (figure in this case), with \centering inside of it, or use \captionof{figure}{...} inside of your center environment. \captionof is provided by the packages capt-of or caption and by the KOMA-script classes (those starting with scr). – Skillmon likes topanswers.xyz Oct 24 '18 at 8:00
• It doesn't matter whether you change the contents of a file, the .aux file is written on every run the file is included. The way you build your document seems wrong, as \section is almost certainly defined if you load a \documentclass, I guess that you tried to compile your chapter file on its own, which won't work. Also your \include of the chapter is after \end{document} which won't do anything. – Skillmon likes topanswers.xyz Oct 24 '18 at 8:05
• If you're using a correct way to build your document and \include your chapter at the right spot (in between of \begin{document} and \end{document}) a \captionof{figure} or a \caption inside of a figure should be written to the correct list (the list of figures that is). – Skillmon likes topanswers.xyz Oct 24 '18 at 8:08
• Thanks for your answer. I have understood what you were explaining abut the problem of the position on th \end{document}, but I'm not sure to have understood the problem of the figure. I modified my code putting \begin{center}[H] \centering \includegraphics[scale=0.5]{Layout.jpg} \caption{Write some caption here} \end{center} but it's still not working. I'm sorry but it's the first time I use latex. – XaBla Oct 24 '18 at 8:20
• You have to use figure not center for a float with a caption. If you for some reason don't want to use a float, you can use \captionof. Correct code would be something like \begin{figure}\centering\includegraphics[<options>]{<image>}\caption{<caption text>}\end{figure}. – Skillmon likes topanswers.xyz Oct 24 '18 at 8:32

You can't use the \caption macro outside of floats (e.g. figure or table environments). For such use cases there is the capt-of package. With it you could use \captionof outside of said environments, so the following could be done with \usepackage{capt-of} in the preamble:

\begin{minipage}
\centering
\includegraphics{example-image-duck}
\captionof{figure}{A friendly looking duck\label{fig:duck}}
\end{minipage}


The above is also possible without the capt-of package if you're using the caption package or a KOMA script class like scrartcl.

But the normal way of including figures is with the figure environment:

\begin{figure}
\centering
\includegraphics{example-image-duck}
\caption{A friendly looking duck\label{fig:duck}}
\end{figure}


Usage of the center environment doesn't seem like a good idea, because it won't prevent page breaks between the graphic and its caption.
