I reinstalled MiKTeX and now I can't make bibliographies anymore. I have a file called a.tex containing

\documentclass{book}
\usepackage[backend=biber]{biblatex}
\bibliography{b}

\begin{document}
\cite{a}
\printbibliography
\end{document}

and b.bib containing

@book{a,
    title={a},
    author={a}
}

Even after compiling multiple times with LaTeX and biber, there is no bibliography and it says that the citation is undefined. Am I missing something? Why doesn't it work? I installed the latest updates in the MiKTeX console.

  • Make sure that your really call Biber on your document/that your editor really runs Biber on your document (check with https://tex.stackexchange.com/q/154751/35864). If you ran the complete LaTeX, Biber, LaTeX, LaTeX cycle there should be a .blg file (on Windows that file may mistakenly be classified as "performance monitor file", but it is a text file you can open with any text editor), please add the complete contents of your .blg file to your question. – moewe Jul 03 '20 at 05:48
  • @moewe Thanks. It actually works now. The default bibliography tool was indeed set to bibtex. But I still find it weird because I could make bibliographies with BibLaTeX using bibtex before. I also tried compiling on the console with biber and it had the same error messages. I don't have the old .blg file anymore. – Luca Jul 03 '20 at 10:42
  • If you load biblatex with backend=biber, you must compile the document with Biber. It is possible that your editor is (or was) configured to run Biber when you click on a button that says "BibTeX", but that doesn't change the fact that only Biber can be used. A Biber run can only be successful after a successful LaTeX run (where "LaTeX" can be your favourite flavour of LaTeX: pdfLaTeX, LuaLaTeX, XeLaTeX). If something is wrong Biber should tell you about it directly when you run it from the command line. – moewe Jul 03 '20 at 11:53
  • @moewe Maybe that's what happened. But since it works now, I'm happy, so thanks. – Luca Jul 03 '20 at 16:29
