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

1
warning (xxx): name (yyy) has been referenced but does not exist, replaced by a fixed one.

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

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:

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}

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

Code, edit and compile here:

1
2
3
\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?

[Stefan Kottwitz]

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