Math & Science ⇒ ntheorem and footnotes

[x42bn6]

Hi all,

If I have a theorem or some environment defined using the ntheorem package, and try and put a footnote somewhere in it, I get the following warning:

Code: Select all

warning (xxx): name (yyy) has been referenced but does not exist, replaced by a fixed one.

It then does not display the footnote.

Any ideas?

Did a lot of searching but couldn't find anything.

Thanks in advance.

Hi,

perhaps post a minimal working example showing the problem and how your code is written. It's probably not necessarily long I guess, reading your description.

Took me a while to get one up. It turns out it's hyperref giving me the warning but the footnote still isn't printing irregardless of whether it's enabled or not:

Code: Select all

%& -shell-escape
\documentclass{article}

\usepackage{amsmath}

\usepackage{framed}

\usepackage[amsmath, amsthm, framed, thmmarks]{ntheorem}

\newframedtheorem{example}{Example}[section]

\begin{document}

\section{Test}
\begin{example}[Foo]
Bar\footnote{Baz}
\end{example}

\end{document}

Compiles without a warning, but does not put a footnote on the page.

Code: Select all

%& -shell-escape
\documentclass{article}

\usepackage{amsmath}

\usepackage{framed}
\usepackage[colorlinks=true]{hyperref}
\usepackage[amsmath, amsthm, framed, thmmarks]{ntheorem}

\newframedtheorem{example}{Example}[section]

\begin{document}

\section{Test}
\begin{example}[Foo]
Bar\footnote{Baz}
\end{example}

\end{document}

Compiles with a warning, decorates the link and does not put the footnote on the page.

So either way it's not really helping me, but I guess if I'm able to put a footnote down then hyperref will behave too.

You could use \footnotemark and \footnotetext:

Code: Select all

\begin{example}[Foo]
Bar\footnotemark
\end{example}
\footnotetext{Baz}

What if I wish to put multiple footnotes in the environment?

[Stefan Kottwitz]

In that case use the optional parameters of both commands, like num in

Code: Select all

\footnotemark[num]
...
\footnotetext[num]{text}

Genius! I've never used those functions before, and I'm guessing they're used in case \footnote doesn't work?

You're right. For example in table environments those commands could be useful too while \footnote might not work.
