[Tex/LaTex] Why \footcite not working in beamer

Question

I wanted to add citations in my beamer presenatation and saw following post.

How to embed citations into footnotes?

For test run I copied the answer posted there but I am not geting ciattaion as shown there. Instaed I m only getting 'foo12' at bottom of my slide.

Can any one tell me whats going wrong here. Is there any new package that i need to add for \documentclass{beamer}

Answer 1

You have to process your document once with pdflatex, then once with biber and then twice again with pdflatex.

With this example (modified from the linked question to use beamer):

\documentclass{beamer}
\usepackage[style=verbose]{biblatex}

\usepackage{filecontents}% to embed the file `myreferences.bib` in your `.tex` file
\begin{filecontents*}{myreferences.bib}
@online{foo12,
  year = {2012},
  title = {footnote-reference-using-european-system},
  url = {http://tex.stackexchange.com/questions/69716/footnote-reference-using-european-system},
}
\end{filecontents*}

% File is created and written to disk by the above package
\addbibresource{myreferences.bib}

\begin{document}

\begin{frame}
Some text.\footnote{Some text in a footnote.} Some more text.\footcite{foo12}
\end{frame}

\begin{frame}
\printbibliography
\end{frame}

\end{document}

The output is:

Check your versions for biblatex and update if necessary. In my system, TeX Live2015, at the moment of this answer:

biblatex.sty    2015/04/19 v3.0 programmable bibliographies (PK/JW/AB)
biblatex2.sty    2015/04/19 v3.0 programmable bibliographies (biber) (PK/JW/AB)
