Biber gives "I found no \citation commands". Is there a solution ? [duplicate]

Question

Help me, please, to fix the work of biber. When I put in biblatex options backend=biber then during the compilation I get:

This is BibTeX, Version 0.99d (TeX Live 2010)
The top-level auxiliary file: test.aux
I found no \citation commands---while reading file test.aux
I found no \bibdata command---while reading file test.aux
I found no \bibstyle command---while reading file test.aux
(There were 3 error messages)

I just updated my TexLive 2010 at 23.05.2011 by the command tlmgr update --all Maybe I do something wrong? Please, help.

After correction: code added

Answer 1

Sometimes (I am not sure why or when) biber gets stuck. It has something to do with running bibtex instead of biber but I haven't pinpointed it. Anyway, if you get a message like

FATAL - Error loading data source package 'Biber::Input::file::bibtex': data source /tmp/par-username/cache-*

then, removing the whole directory should solve the problem.

You can find which directory you must remove by running biber --cache.

In Linux the command is:

 rm -r <directory-name>

Note: Do replace <directory-name> with the output of the command.

In windows, if the problem exists there too, propably the solution will be something similar, I haven't checked it though.

Update (after PLK's comment)

For more info look at the biber manual (sec. 3.1).

Answer 2

Well if you tell biblatex that you intend to use the backend biber (backend=biber) then you should do it and not call bibtex. With backend=biber biblatex puts the informations in a bcf file and not in the aux so it is not a surprise that bibtex can't find them.
