Problem with Biber citation [duplicate]

I have used biber succesfully, but now I have ran into a problem. My pdf files look like this: This citation is not working (eco_theory_1979). When I typeset this tex file:

\documentclass[a4paper,12pt]{article}
\usepackage{fontspec}
\usepackage[norsk]{babel}
\usepackage[style=apa,backend=biber]{biblatex}
\DeclareLanguageMapping{norsk}{norsk-apa}
\bibliography{test}

\begin{document}
This citation is not working \parencite{eco_theory_1979}.
\printbibliography
\end{document}


Here is the bib file

@book{eco_theory_1979,
Author = {Eco, Umberto},
Date-Modified = {2014-07-28 17:35:21 +0000},
Isbn = {0253202175, 9780253202178},
Publisher = {Indiana University Press},
Title = {A theory of semiotics},
Year = {1979}}


This is what the log file reports:

No file test.bbl.
LaTeX Warning: Citation 'eco_theory_1979' on page 1 undefined on input line 13.
LaTeX Warning: Empty bibliography on input line 15.
LaTeX Warning: There were undefined references.
Package biblatex Warning: Please (re)run Biber on the file:
(biblatex)                test
(biblatex)                and rerun LaTeX afterwards.


Previously I have compiled similar files without problems. There seem to be a problem that no bbl file is created. I am using TexPad on a Mac and have tried to compile in several ways (autodetect, bibtex...) I will be very happy if anyone can help

• Btw: There is no cite in your example. \begin{document} is missing as well. Having added that, the example runs just fine. – Johannes_B Nov 24 '14 at 8:21
• I runned your MWE using TeXstudio on Windows 7 and all worked fine. I used the sequence: XeLaTeX -> Biber -> XeLaTeX – Smarzaro Nov 24 '14 at 12:04
