modifying .aux output \bibdata, using biblatex/bibtex8 with a build directory

Question

I want to use biblatex and I get got an error when using bibtex8 (or other backend, doesn't matter). I already identified the problem: I am using a 'build' direcotry.

So my file stucture is:

myfile.tex
mybib.bib
/build [all copiled files go here, including myfile.aux and myfile-blx.bib]

in my .tex I have:

\addbibresource{mybib.bib}

which produces the following in the .aux file:

\bibdata{myfile-blx,mybib}

now bibtex8 is run from the base directory with (Texmaker):

bibtex8 --wolfgang build/%

it correctly finds the .aux file and the mybib.bib file but not the -blx.bib file.

I have three workarounds so far:

• not using a build directory so everything is in one directory (i don't like that)
• manually copy the -blx.bib file to the parent directory after running (pdf)latex
• manually editing the .aux file to: \bibdata{build/myfile-blx,mybib}

Obviously none of them desireable.

So how can I get this line in my .aux file automatically?

\bibdata{build/myfile-blx,mybib}

EDIT 2012-09-04:

@Kurt: Thanks for you tip!

@PLK: I would try to use biber. But I am working with this on two machines. And the main workstation is Windows 7 64 bit, and there is no binary for that on the biber homepage. And the 32 bit does not execute.

@Kurt(2): I am running on [Windows 7, 64 bit, miktex, texmaker, jabref] mainly and also on [xubuntu, 32 bit, texlive, texmaker, jabref].

I personaly think a minimal example is not that helpfull since everything compiles without any errors unless i'am using a build directory. MWE:

\documentclass[a4paper, fontsize=12pt]{scrartcl}
\usepackage{filecontents}
\begin{filecontents}{mybib.bib}
% This file was created with JabRef 2.8.1.
% Encoding: ISO8859_1

@ARTICLE{author2010,
  author = {Some Author},
  title = {Fancy Title},
  journal = {Another Journal},
  year = {2010},
  volume = {91},
  pages = {229-261},
  number = {2},
  timestamp = {2012.09.01}
}

\end{filecontents}

\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc} 
\usepackage[ngerman]{babel}

\usepackage{csquotes}
\usepackage[backend=bibtex8,bibencoding=latin1]{biblatex}
\addbibresource{mybib.bib}

\begin{document}

\section{Section}
Lots of text.
\footnote[111]{\cite[S.~250--255]{author2010}}

\printbibliography

\end{document}

As said above everything runs without any error without a build dirctory. When I use a build directory the first pdflatex run works fine. And then bibtex8 produces the following error/output in the ./build/myfile.blg file:

The 8-bit codepage and sorting file: 88591lat.csf
The top-level auxiliary file: build/myfile.aux
The style file: biblatex.bst
I couldn't open database file myfile-blx.bib
---line 4 of file build/myfile.aux
 : \bibdata{myfile-blx
 :                    ,mybib}
I'm skipping whatever remains of this command

This is because it expects myfile-blx.bib and mybib.bib to be both in the parent directory ./. As stated above i can workaround by maually editig the .aux file before running bibtex8. When I do that it runs without errors.

Answer 1

The --output_directory option of biber deals with this.
