[Tex/LaTex] Chapterbib with subdirectories does not compile

bibtex

I'm using chapterbib package to generate a bibliography for each chapter. But the compilation fails.

Here is the content of my principal.tex file:

\documentclass[phd]{theseUL}

\usepackage{lmodern}
\usepackage[utf8]{inputenc}
%\usepackage[french]{babel}
\usepackage{fancyhdr}
\usepackage{amsfonts}
\usepackage{url}
\usepackage{hyperref}
\usepackage{graphicx}
\usepackage{color}
\usepackage{verbatim}
\usepackage{enumerate}
\usepackage{makeidx}
\usepackage{topcapt}
\usepackage{setspace}
\usepackage{rotfloat}

\usepackage[square,sort,comma, authoryear]{natbib}
\usepackage{chapterbib}

\begin{document}

\part{Contexte général et état de l'art}
\include{../chap1_introduction/chap1_introduction}
\input{../chap2_definitions/chap2_definitions}

\end{document}

Here is the content of chap1_introduction.tex

\chapter{Introduction}  %%This is chapter 1

\phantomsection\addcontentsline{toc}{chapter}{Introduction}

Text

\bibliographystyle{authordate1}
\bibliography{principal}

And so for the content of chap2_definitions.tex

\chapter{Definition} %%This is chapter 2

\phantomsection\addcontentsline{toc}{chapter}{Definition}

Text

\bibliographystyle{authordate1}
\bibliography{principal}

This is how I compile my documents:

  1. pdflatex principal.tex (success)
  2. pdflatex principal.tex (success)
  3. bibtex principal (2 errors, I guess it is normal: see output #1)
  4. bibtex ../chap1_introduction/chap1_introduction (see output #2)
  5. bibtex ../chap2_definitions/chap2_definitions (see output #3)
  6. pdflatex principal.tex
  7. pdflatex principal.tex

Output #1

output #3 is same than output #2

principal.bib is the entire citation databse for the whole document and is in /principal; so I have principal/principal.bib.

Should I compile the chapters bibtex from the chapter subdirectory, or from the principal subdirectory as I did? I tried both withe the same result.

Thank you.

I already answered here on LaTeX-Community, but also here my answer. I can see that you use \input for including the chapters in this line:

\input{../chap2_definitions/chap2_definitions}

However, you should use \include instead, this way you would get .aux files for each chapter which can be processed. Otherwise, with \input, you would need \cbinput or the cbunit environment. However, \include is strongly recommended. You use chapters, for sure starting a new page, so \include would be fine.

Here's also a solution: chapterbib | References following each Chapter. Also there, the solution was using \include but additionally having the files in the same directory.
