# Undefined Citation natbib / Failing to print References

I am using the natbib package to manage my references for my thesis. Unfortunately the citations are undefined and it prints "?" in the pdf rather than the actual Citation from my bib file. Neither are my references printed. I am using texmaker. Does anybody know how to solve my problem? Do i have to compile it in a specific order? I usually compile: PDFLatex - Bibtex - PDFlatex - show pdf latex.

Here is my code:

\documentclass[12pt,a4paper]{article}

%% Font
%\usepackage{mathpazo}
%% Mathematics
\usepackage{amsmath, latexsym}
%% Graphics
\usepackage{graphicx}
%% Line spacing
\usepackage[onehalfspacing]{setspace}
%% Bibliography
\usepackage[round]{natbib}
\bibliographystyle{abbrvnat}

\usepackage{float}
\usepackage{booktabs}
\usepackage{footnote}
\usepackage[flushleft]{threeparttable}
\usepackage{lscape}

\newcommand{\eg}{{\it e.g.}}
\newcommand{\ie}{{\it i.e.}}

• On first glance the code shown so far looks OK and the compilation cycle (LaTeX, BibTeX, LaTeX) is also OK. Can you show us the .bib entry akerlof2000economics. Please also check the .blg and .log files for warning or error messages. – moewe Jul 20 at 8:58
• if i run the .bib file following error appears: ERROR - Cannot find control file 'References.bcf'! - did you pass the "backend=biber" option to BibLaTeX? INFO - ERRORS: 1. My bib file looks like follow: @article{akerlof2000economics, title={Economics and identity}, author={Akerlof, George A and Kranton, Rachel E}, journal={The Quarterly Journal of Economics}, volume={115}, number={3}, pages={715--753}, year={2000}, publisher={MIT Press} } – LAH17 Jul 23 at 13:08
• You appear to be running Biber, when you should be running BibTeX. Follow tex.stackexchange.com/q/154751/35864 in reverse to make sure your editor is configured to run BibTeX and not Biber. Note that in any case you don't run BibTeX or Biber on the .bib file, you run it on the basename of your .tex file (or BibTeX on the .aux and Biber on the .bcf). – moewe Jul 23 at 14:13
