As a test, I've got this most simple .tex file:
\documentclass{article}
\usepackage[backend=biber]{biblatex}
\addbibresource{src.bib}
\begin{document}
Test test test \cite{abc}
\printbibliography
\end{document}
with src.bib:
@article{abc,
title={abc},
author={def}
}
yet the result is :
The text between square brackets is simple the argument I call in \cite and the output logs a warning:
warning empty bibliography
I assume it doesn't work because of the empty bibliography but I've no idea what I'm doing wrong. The .tex file and the .bib file are in the same directory. My editor is TeXstudio.
This question does also not help and omitting the backend part gives the same result
