# I am having trouble with my reference page in Beamer

I am doing a Beamer presentation and my reference page won't load. Here is my code that I am using

\usepackage{amsmath}
\usepackage{biblatex}
\bibliography{Master.bib}

\begin{frame}{References}
\nocite{*}
\printbibliography
\end{frame}


and here is what my Master.bib looks like

@article{hafsteinsson2009porous,
Author = {Hafsteinsson, Haukur Elvar},
Date-Modified = {2017-04-03 05:13:42 +0000},
Journal = {Chalmers University of Technology, Gothenburg},
Title = {Porous media in OpenFOAM},
Year = {2009}}

@article{domaingo2016semi,
Author = {Domaingo, Andreas and Langmayr, Daniel and Somogyi, Bence and Almbauer, Raimund},
Date-Modified = {2017-04-03 05:12:59 +0000},
Journal = {Transport in Porous Media},
Number = {2},
Pages = {451--466},
Publisher = {Springer},
Title = {A Semi-implicit Treatment of Porous Media in Steady-State CFD},
Volume = {112},
Year = {2016}}


I have done everything that I could find which was not using the \bibliography{Master.bib} tag and use it directly into the reference frame but that still didn't work and I also changed around \bibliographystyle{•} but when I don't have it in I don't get any errors and it builds it but without any references on the page. I have done PDFLaTeX, BibTeX, PDFLaTeX, PDFLaTeX, as well and that didn't help with my issue. I also do have the Master.bib in the same directory as all of my .tex files. Any help would be greatly appreciated.

biblatex has its own data backend processor, biber, which is the default when you don't specify anything:

\usepackage{biblatex}


hence, you have to compile your document with: pdflatex > biber > pdflatex > pdflatex, notice the biber instead of bibtex (this is the best solution).

If you use arara, it does it for you (the first 4 line here are necessary only if you use it):

% arara: pdflatex
% arara: biber
% arara: pdflatex
% arara: pdflatex
\begin{filecontents}{Master.bib}
@article{hafsteinsson2009porous,
Author = {Hafsteinsson, Haukur Elvar},
Date-Modified = {2017-04-03 05:13:42 +0000},
Journal = {Chalmers University of Technology, Gothenburg},
Title = {Porous media in OpenFOAM},
Year = {2009}}

@article{domaingo2016semi,
Author = {Domaingo, Andreas and Langmayr, Daniel and Somogyi, Bence and Almbauer, Raimund},
Date-Modified = {2017-04-03 05:12:59 +0000},
Journal = {Transport in Porous Media},
Number = {2},
Pages = {451--466},
Publisher = {Springer},
Title = {A Semi-implicit Treatment of Porous Media in Steady-State CFD},
Volume = {112},
Year = {2016}}
\end{filecontents}

\documentclass[12pt]{beamer}

\usepackage{amsmath}
\usepackage{biblatex}

\bibliography{Master.bib}

\begin{document}
\begin{frame}{References}
\nocite{*}
\printbibliography
\end{frame}
\end{document}


The second best solution, if you want to use the bibtex backend processor, is to write:

\usepackage[backend=bibtex]{biblatex}


and compile with: pdflatex > bibtex > pdflatex > pdflatex (or, if you use arara, adding the first 4 lines you find here):

% arara: pdflatex
% arara: bibtex
% arara: pdflatex
% arara: pdflatex
\begin{filecontents}{Master.bib}
@article{hafsteinsson2009porous,
Author = {Hafsteinsson, Haukur Elvar},
Date-Modified = {2017-04-03 05:13:42 +0000},
Journal = {Chalmers University of Technology, Gothenburg},
Title = {Porous media in OpenFOAM},
Year = {2009}}

@article{domaingo2016semi,
Author = {Domaingo, Andreas and Langmayr, Daniel and Somogyi, Bence and Almbauer, Raimund},
Date-Modified = {2017-04-03 05:12:59 +0000},
Journal = {Transport in Porous Media},
Number = {2},
Pages = {451--466},
Publisher = {Springer},
Title = {A Semi-implicit Treatment of Porous Media in Steady-State CFD},
Volume = {112},
Year = {2016}}
\end{filecontents}

\documentclass[12pt]{beamer}

\usepackage{amsmath}
\usepackage[backend=bibtex]{biblatex}

\bibliography{Master.bib}

\begin{document}
\begin{frame}{References}
\nocite{*}
\printbibliography
\end{frame}
\end{document}


However, in your case, the output is the same:

• Thank you for your response I have written down what you gave but when I build it I get the following error: Error : could not start the command : "/Library/TeX/texbin/bibtex" "Math Presentation".aux If it does make a difference I am using TexMaker on a Mac, but I figured it shouldn't overly. And I do have the proper paths set up for Mac as well for TexMaker Apr 3, 2017 at 14:54
• @Robert In your question you said you have run PDFLaTeX, BibTeX, PDFLaTeX, PDFLaTeX. You only need to run PDFLaTeX, Biber, PDFLaTeX, PDFLaTeX with your original document. Delete the auxiliary files before doing it. Apr 3, 2017 at 14:59
• My apologies for some reason on my laptop the commands we not working properly (I probably need to do a reinstall) which is what I used to build your result and hence gave me the error, but I did build it with your result on my desktop and it worked perfectly (My desktop is what I used initially for my writing of the beamer presentation) I appreciate your help.

• @Robert Don't worry, on your laptop, before re-installing, try to delete the auxiliary files and then compile with PDFLaTeX, Biber, PDFLaTeX, PDFLaTeX. Apr 3, 2017 at 15:08
