# strange error in \end{document}

I am using ACM template to write a paper for a conference. This is my main document structure:

.....

\section{Introduction}
\label{sec:Introduction}
\input{introduction}

\section{Related Work}
\label{sec:rWork}
\input{relatedWork}
...
\section{Concluding Remarks}
\label{sec:conclusion}
\input{conclusion}

\bibliographystyle{abbrv}

\end{document}


Somehow every time I create pdf (PDF Textify) using WinEdt. I get strange error as shown in the following image.

pdfTeX warning (ext4): destination with the same identifier (name{page.}) has
been already used, duplicate ignored
<to be read again>

• Welcome to TeX.SX! Please add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}. As to the error message, check this and this – henrique Aug 18 '13 at 14:27
• It is not an error, but just a hyperref warning. See tex.stackexchange.com/q/124520/27635. You're using a very very old WinEdt version, and probably it is reported as an error. I suggest you to upgrade to the latest version (8.0) – karlkoeller Aug 18 '13 at 14:38

Probably you have several pages with \renewcommand*{\thepage}{}. Package hyperref adds page anchors at each page. They are used by index commands, thus \thepage is used for naming the anchors.

If you do not have an index, then you can add the following hyperref option:

pageanchor=false


Otherwise, page anchors can be disabled for some pages only, e.g.:

\hypersetup{pageanchor=false}
\renewcommand*{\thepage}{}
...

\pagenumbering{arabic}
\hypersetup{pageanchor=true}
