Is there a problem with using the cite package within a beamerposter? I'm trying to use it so that my references are ordered when I call \cite{ref1,ref2,ref3}, but I get the error:

./main.tex:333: Undefined control sequence.
\@cite@n ...mpcnta \m@ne \mathchardef \@cite@incr 
                                                  \z@ \let \@h@ld \@empty \l...

This is a sample source file which will generate the error. To test this, you will need to input your own .bib file with the appropriate references.


\usepackage[scale=1.24]{beamerposter} % Use the beamerposter package for laying out the poster

\usetheme{confposter} % Use the confposter theme supplied with this template

\setlength{\paperwidth}{48in} % A0 width: 46.8in
\setlength{\paperheight}{36in} % A0 height: 33.1in
\setlength{\sepwid}{0.024\paperwidth} % Separation width (white space) between columns
\setlength{\onecolwid}{0.22\paperwidth} % Width of one column
\setlength{\twocolwid}{0.464\paperwidth} % Width of two columns
\setlength{\threecolwid}{0.708\paperwidth} % Width of three columns
\setlength{\topmargin}{-0.5in} % Reduce the top margin size

\usepackage{graphicx}  % Required for including images

\usepackage{booktabs} % Top and bottom rules for tables


\title{TEST} % Poster title




\setlength{\belowcaptionskip}{2ex} % White space under figures
\setlength\belowdisplayshortskip{2ex} % White space under equations



    \begin{column}{\onecolwid} % The first column


        CITATIONS \cite{ref1,ref2}.  







Is it simply not possible to use the cite package with the beamerposter? Is there an alternative?

    Please post not only the error message but a minimal example that gives rise to the error.

  • Use \cite{article-full,book-full} and \bibliography{xampl}, then everyone will be able to run your example directly (xampl.bib is included with BibTeX, I believe). Aug 24 '17 at 14:13
  • Works fine if I insert some dummy citations from my .bib file. Please make a minimal working example with bibliography (MWEB) Aug 24 '17 at 14:14
  • Does it work with \usepackage[sort&compress,numbers]{natbib} instead of \usepackage{cite}? (@samcarter Hm, I could reproduce the error.) Aug 24 '17 at 14:16
  • @TorbjørnT. Interesting! I used the following code pastebin.com/gqBeqrcU with pdflatex without problems. Aug 24 '17 at 14:19

The error does not occur with an up-to-date TeX Live 2017, so some of your packages appear to be outdated. If updating is not an option, an alternative to \usepackage{cite} is
