BibTeX, biblatex and biber ⇒ Citation Errors with Chicago Bibliography Style

[Sire El Fatos]

Dear (bib)latex users,

I'd greatly appreciate any help with this issue.

With this minimal example:

Code: Select all

\documentclass[11pt,a4paper]{report}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[english,francais]{babel}

\begin{document}
Hello world \cite{toto}

\bibliographystyle{chicago}
\bibliography{Biblio}
\end{document}

A bibliogrpahy file (named "Biblio.bib") like this:

Code: Select all

@article{toto,
  author = {tata},
  title = {tonton},
  journal = {titi},
  year = {2013},
}

I get these two errors :

Code: Select all

! Undefined control sequence.
\b@toto ->\@safe@activesfalse \citeauthoryear
{tata}{tata}{2013}
l.14 \cite{toto}

! Undefined control sequence.
<argument> \protect \citeauthoryear
{tata}{tata}{2013}
l.3 ...ect\citeauthoryear{tata}{tata}{2013}]{toto}

If I change the bibliography style (for example plain, apalike, ...), there are no errors anymore.

Thank you in advance for your precious help.

Hi Sire El Fatos,

Welcome to the LaTeX community!

It looks like the chicago style needs the natbib package:

Code: Select all

\RequirePackage{filecontents}
\begin{filecontents}{somesample.bib}
@article{toto,
  author = {tata},
  title = {tonton},
  journal = {titi},
  volume = {1} ,
  pages = {203},
  year = {2013},
}
\end{filecontents}
\documentclass[11pt,a4paper]{report}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{natbib}
\usepackage[english,francais]{babel}

\begin{document}
Hello world \cite{toto}

\bibliographystyle{chicago}
\bibliography{somesample}
\end{document}

Regards

Thanks for you help, Cgnieder !
