[Tex/LaTex] Texmaker bibliography issues

biblatexbibliographies

I am having issues with trying to compile a bibliography using TexMaker (I'm very new to LaTex). I have found multiple Google hits with the same error message as I've been having all day

The top-level auxiliary file:..... I found no \bibdata command-"

and I found a walkthrough using biblatex from Cambridge University

http://www-h.eng.cam.ac.uk/help/tpl/textprocessing/biblatex.html

but I still can't compile the bibliography for some reason. This is my MWE:

%test1.tex
\documentclass{article} 

\usepackage{biblatex} 
\bibliography{refs} 

\begin{document} 
Hello\cite{KandR}
\printbibliography 
\end{document}

The refs.bib is as follows.

%refs.bib

@BOOK
  {KandR,
   AUTHOR  = "Kernighan, Brian W. and Ritchie, Dennis M.",
   TITLE   = "{The C Programming Language Second Edition}",
   PUBLISHER = "Prentice-Hall, Inc.",
   YEAR = 1988
  }

I perform PDFLatex -> Bibtex -> PDFLatex -> PDFLatex. During the first PDFLatex I get the following error message.

No "backend" specified, using Biber backend.
Citation 'KandR' on page 1 undefined
Empty bibliography
>There were undefined references.
Please (re)run Biber on the file:(biblatex) test1(biblatex) and rerun LaTeX afterwards.

and the error message associated with BibTex

Process started
This is BibTeX, Version 0.99d (MiKTeX 2.9) The top-level auxiliary file: test1.aux I
found no \citation commands---while reading file test1.aux I found no \bibdata command---
while reading file test1.aux I found no \bibstyle command---while reading file test1.aux
(There were 3 error messages)
Process exited normally

Am I missing something?

The error

No "backend" specified, using Biber backend.

gives the hint that biblatex is using biber. But you are using bibtex during compilation. biblatex uses biber by default (when no backend is specified). You can over come this by using

\usepackage[backend=bibtex]{biblatex}

to force biblatex use bibtex as the backend.

Here is a more minimal AND working example, using biber not bibtex

Note that biber complains about the format of the date, so you'll need to look that up in the biblatex manual.

You probably mean urldate not date, and then the syntax is YYYY-MM-DD, so

urldate = {2016-04-11},

in this case.

 \documentclass[a4paper, 12pt]{report}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}  
 \usepackage[style=authoryear]{biblatex}
\usepackage{csquotes}
\usepackage{filecontents}

\begin{filecontents*}{rapport.bib}
  @online{cim-wiki,
    author = {Wikipedia},
    title = {Common Information Model (electricity)},
    urldate = {2016-04-11},
    url =    {https://en.wikipedia.org/wiki/Common_Information_Model_(electricity)},
  }
\end{filecontents*}


\bibliography{rapport}

\begin{document}

   \chapter{Bibliographie}

\cite{cim-wiki}

   \printbibliography
   \end{document}

[Tex/LaTex] Bibtex finished with 3 error messages

You asked,

>This is the route to follow, isn't it?
>    compile main.tex with pdflatex       [this generates main.aux]
>    launch BibTex on main                [this generates main.bbl]
>    compile main.tex with pdflatex twice [this incorporates main.bbl into the pdf file]

This would indeed be the route to follow if your document were using BibTeX. However, since your document uses the biblatex package with the option backend=biber, you should be running biber, not BibTeX. For your document, then, the correct sequence is:

> run pdfLaTeX on main[.tex]
> run biber on main
> run pdfLaTeX on main

Incidentally, you should replace the deprecated instruction \bibliography{articles} with

\addbibresource{articles.bib}

Two comments about the linespread choice: (a) Don't manipulate the low-level TeX parameter \linespread directly. Instead, load the setspace package and issue the directive \setstretch{1.5}. (b) One indeed does encounter the recommendation that leading should be slightly looser with a Palatino font. However, that recommendation is generally for a factor around 1.04 or 1.05, never 1.5! If you absolute must increase the leading, by all means to do. Just don't claim you're doing so because Palatino somehow requires it...

\RequirePackage{filecontents}
\begin{filecontents}{articles.bib}
@misc{a:3001,
  author = "Anne Author",
  title  = "Initial Thoughts",
  year   = 3001,
}
@misc{z:3002,
  author = "Zo{\"e} Zwicky",
  title  = "Final Thoughts",
  year   = 3002,
}
\end{filecontents}
