I am facing a strange situation using Beamer

  1. Bibliography is not printing in the last slide(s)
  2. Only the reference key words are printed in the slide footer. But I need the full citation to be printed
  3. If possible i would like to have the bibliography style ieeetr in the footers and last slide(s)

I am using TeX Studio compiling chain used : pdflatex - bibliography - pdflatex - pdflatex

What seems to be the problem?

Thanks in advance for the help.

Please find the MWE and bib file below

Thank you

JIM

  • \addbibresource needs the file name of your .bib file with file extension. So \addbibresource{references} should presumably be \addbibresource{references.bib}. You also need to run Biber on your document so that a whole compile cycle is pdfLaTeX, Biber, pdfLaTeX, pdfLaTeX. Have a look at https://tex.stackexchange.com/q/154751/35864 to configure your editor for Biber. (If you use pdflatexmk that should run Biber for you automatically, but it is not clear to me whether you actually ensure that pdflatexmk is used as suggested by the file header). – moewe Mar 06 '21 at 15:02
  • Note that your reference.bib as shown does not contain a reference called ieee and that you probably want to use \footfullcite and not just \footcite everywhere. – moewe Mar 06 '21 at 15:06
  • Thank you for the answer, infact I followed the steps in the above stack exchange post Now I have made the following changes: \addbibresource{references.bib} , used \footfullcite{} , removed the invalid reference from tex file. But I get the same error messages and the old output itself. The error messages are posted below Error: One command expansion invalid. Parent Command: bibliography Primary Command: bibliography – Joaquim Mar 06 '21 at 15:28
  • Please update the code with the changes you have made (it still says \addbibresource{references}, which is incorrect, and now uses \footcite where you said you had used \footfullcite in your last comment). Please also add the exact message of the error to the question. The error message you mention does not sound like a LaTeX or Biber error, so maybe you did not configure your editor correctly. Please show a screenshot of your editor config and compare it again against https://tex.stackexchange.com/q/154751/35864. – moewe Mar 06 '21 at 15:32
  • I get an error message when biber is run on the tex file Command txs:///biber not defined – Joaquim Mar 06 '21 at 15:44
  • OK, then something with your editor configuration is wrong. Please explain exactly how you tried to set your editor up for Biber. Add pictures if that helps. (Please do not say "I followed the steps in ") – moewe Mar 06 '21 at 15:47
  • Thanks for your patience – Joaquim Mar 06 '21 at 15:50
  • I am on Ubuntu 20.04, how to configure the biber command? – Joaquim Mar 06 '21 at 15:55
  • Let us continue this discussion in chat. – Joaquim Mar 06 '21 at 15:56

    For some reason your Biber configuration in the editor has <unknown>. It should say biber % instead. – moewe Mar 06 '21 at 16:34

    If you have not installed Biber yet you may have to do that with (sudo) apt install biber. – moewe Mar 06 '21 at 17:03
  • Thank you so much. apt install biber did the trick. I had installed bibtex-extra (apt install texlive-bibtex-extra) and assumed that biber would be part of it. – Joaquim Mar 07 '21 at 09:27
