Bibliografia vuota? Riferimenti vuoti?

Salve a tutti,
sto incontrando serie difficoltà con la bibliografia, credo a causa di qualche settaggio non corretto che però non riesco a capire quale sia.

Premetto col dire che sto cercando di far funzionare prima il tutto con un minifile di prova per poi passare alla bibliografia della tesi vera e propria.

`
\documentclass{article}
\usepackage{filecontents}
\begin{filecontents*}{\jobname.bib}
@ARTICLE{example,
author = {Other, Anthony Norman},
title = {Some things I did},
year = {2014},
journal = {J.~Irrep. Res.},
volume = {1},
number = {1},
pages = {1-10}
}
\end{filecontents*}
\usepackage[backend=biber]{biblatex}
\addbibresource{\jobname.bib}
\begin{document}
Hello\cite{example}.
\printbibliography
\end{document}
`

Utilizzo con ubuntu l’editor TexMaker che ho configurato così che l’ordine di compilazione sia: pdflatex + bibtex + pdflatex e ho editato i comandi in modo che in Bib(La)Tex ci sia:

`”/opt/texbin/biber” %`

Lanciando la compilazione il log di biber è

`

Mi sembrerebbe tutto okay dato che controllando in TexLive Manager la versione biblatex installata è la 3.2

Quello che mi da pensiero è il file di log

Sembra che venga utilizzata una versione di biblatex che non è quella di CTAN? Eppure ho seguito la guida per l’installazione di TexLive su Linux e which tex risponde con il path corretto… E’ questo il problema?

Utilizzando bibtex come backend (e impostando il path di bibtex in texmaker /opt/tex/bibtex) invece tutto funziona..

Grazie a tutti dell’aiuto PREZIOSISSIMO!
