I have been getting weird undefined reference errors to 'Last Page' that point to the line corresponding to my end{document}. I have no idea what this means, but in any case, here is a minimum working example.

\documentclass[a4paper,UKenglish]{lipics-v2016}
\begin{document}
\begin{abstract}
Abstract \ldots
\end{abstract}
\end{document}

This produces the following: "LaTeX Warning: Reference `LastPage'", "Package lastpage Warning: Rerun to get the references right on input line". I also get things like "LaTeX Warning: Label(s) may have changed. Rerun to get cross-references right." no matter how many times I rerun LaTeX. Any advice? I am using Miktex 2.9.

Note: The lipics-v2016.cls file is very large, but can be downloaded here http://drops.dagstuhl.de/styles/lipics-v2016/lipics-v2016-authors.tgz

Edit: I also get the above errors on the starter files without even making changes. This leads me to believe it may be an issue with Miktex. I noticed that Miktex is not producing any .aux or .bbl or .log files... which may be the cause of the error. If I include a bibliography, then no matter what I do, each reference causes a warning.

  • How exactly do you run (pdf)LaTeX on your document? – Torbjørn T. May 30 '16 at 5:59
  • I just click the typeset button with the options 'pdflatex + makeindex + bibtex'. – user340082710 May 30 '16 at 6:00
  • Hm. What if you try with just pdfLaTeX? Does the .aux file end up in a subfolder? The warning (it's not an error, just a warning) is gone on the second compilation run when I test it here. – Torbjørn T. May 30 '16 at 6:29
  • if you (or your editor) are removing the aux file then the cross reference warning will never go, so ignore the warning, and work out where the aux file went. – David Carlisle May 30 '16 at 8:22
  • @TorbjørnT. Using just pdfLaTeX creates all of the required files and then the warning appear to go away after the second typeset, as expected... Why would this cause an issue? I am so puzzled. – user340082710 May 30 '16 at 12:29
