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

This question already has an answer here:

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

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Could you give us an example of the tex file that caused these errors? Did you try deleting all the auxiliary files and recompiling? – Seamus May 23 '11 at 12:36
check here for a mwe involving greek and english references. – pmav99 May 23 '11 at 12:40
You are telling biblatex to use Biber, but your log is from BibTeX. – Joseph Wright May 23 '11 at 13:14
@Seamus I've tried to delete all aux files, but it doesn't help. :( There is a code above. – filokalos May 23 '11 at 13:14
@pmav99 Malista. Thank you. :) – filokalos May 23 '11 at 13:21

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).

SUPER! Thank you. :))) – filokalos May 23 '11 at 14:53
This is usually due to the way Biber is 'packed' for portability. On first run, it has to extract various bits of code, and if this goes wrong or gets interrupted then you get errors like the one seen. – Joseph Wright May 23 '11 at 15:47
@Joseph Thank you – pmav99 May 24 '11 at 7:40
See section 3.1 of the biber manual - it explains this and gives the common locations on various OSes of the par archive folder you can delete to fix it. – PLK May 26 '11 at 17:07
@PLK thank you mate. I updated the answer. – pmav99 May 27 '11 at 13:56

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.

Thank you Could you please tell me more detailed? I'm not very common with this theme. So what should I do? – filokalos May 23 '11 at 13:20
Use biber instead of bibtex. – Ulrike Fischer May 23 '11 at 13:26
@Ulrike Fischer I've tried. It writes "FATAL - Error loading data source package 'Biber::Input::file::bibtex': data source /tmp/par-filokalos/cache-6a1f654c9b57c7ffeb35998422a4089cb0e12294/inc/lib/Biber/‌​Input/file/bibtex.dcf not found in ." – filokalos May 23 '11 at 13:32
I don't have texlive so I can't help you in debugging its biber version. – Ulrike Fischer May 23 '11 at 13:46
Ok. Thank you for help. At least now I know where is the problem. – filokalos May 23 '11 at 13:56
