I am trying to show the bibliography in a LaTeX document. But \printbibliography does nothing. I am using biblatex with bibtex8 as backend. Here is the code:
\documentclass[liststotoc,bibtotoc,a4paper,12pt,parskip,final]{scrbook}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{ae,aecompl}
\usepackage[ngerman]{babel}
\usepackage{setspace}
\usepackage{graphicx}
\usepackage[babel,german=guillemets]{csquotes}
\usepackage[backend=bibtex8]{biblatex}
\usepackage{hyperref}
\usepackage[nolist]{acronym}
\usepackage[paper=a4paper,left=25mm,right=25mm,top=30mm,bottom=40mm,bindingoffset=1cm]{geometry}
\hbadness = 10000 % -> disable ``underfull \hbox'' warnings
\parindent 0pt % keine einrückung nach absätzen
\bibliography{literature}
\begin{document}
\frontmatter % keine kapitelnummern, römische seitenzahlen
\include{./texFiles/titelblatt}
\onehalfspacing
\tableofcontents
\listoffigures
% \include{./texFiles/abkuerzungsverzeichnis}
\mainmatter
\include{./texFiles/01_einleitung}
\include{./texFiles/02_grundlagen}
\include{./texFiles/03_konzept}
\frontmatter
\setcounter{page}{15} % seitenzahl counter auf 15 setzen
% \include{./texFiles/literaturverzeichnis}
\printbibliography
\end{document}
Any idea what the problem is?
