I am so sure it is just a minor problem, yet I try to solve it since days without any progress, so I would be glad for any help:
I recently switched to biblatex - and my document fails to produce a bibliography and proper citations (it just gives the key in bold and brackets). I reinstalled everything several times but stll assume somehow biber does not run properly. I use Biber 1.8, Miktex 2.9 (32 bit) and Texniccenter.
So what I do:
\documentclass[12pt,a4paper]{scrreprt}
\usepackage[style=authoryear-comp,natbib=false,mcite=false,backend=biber]{biblatex}
\addbibresource{refs.bib}
\begin{document}
blabla \cite{key}
\printbibliography
\end{document}
My refs file does exist and is found, still I get the warnings:
Citation 'key' on page 1 undefined on input line 7.
Biber tells me:
This is Biber 1.8 - Logile is 'xy.blg' - Reading 'xy.bcf' - Found 42 citekeys in bib section o - Processing 0 - Looking for bibtex format file 'refs.bib' - Than a number of warnings (not parse correctly, Duplicate entry key...) - and then: BibTex subsystem: C\User... \AppData\LocalTemp\NJf6qjXqel\refs.bib_57752.utf8, line 1, warning: 9 characters of junk seen at toplevel and then an Error (all former = warnings) C\User... \AppData\LocalTemp\NJf6qjXqel\refs.bib_57752.utf8, line 5187, syntax error: found"(", expected","
So what do I do wrong??
Update: Problem was with the .bib file - imported automatically from Citavi.
.bib
file is not well-formed. (Duplicate entry key does not sound too good). Can you perhaps narrow the problem down by selectively removing entries until the error goes away (go to those pointed to by the error message first).{
and close with"
for example.
