Warning building in Sublime Text XeLaTeX BibLaTeX

TeX - LaTeX Asked by Marly T Celis on June 2, 2021

I’m having quite some unpleasant moments every time I build my LaTeX documents using Sublime Text 3. Every time I compile a document I get the following warning

LaTeX Warning: You have requested, on input line 37, version 2018/01/30' of package pdftexcmds, but only version 2018/01/21 v0.26 Utility functions of pdfTeX for LuaTeX (HO)’ is available.

(Yes. pdftexcmds)

The weird part is that this happens even when I have nothing in line 37. AND, when I manually go to the command pallete and select Build with: Latex- Basic Builder Xelatex: the code runs and prints the references as expected (I still get a warning though).

How to avoid this warning in the future?
What is the incompatibility between Xelatex and BibLaTeX?
What is this warning about? I have no clue how to solve this.

The toy code is:

documentclass[11pt]{article}
usepackage[english]{babel}
usepackage{fontspec}
defaultfontfeatures{Ligatures=TeX}
usepackage[a4paper,margin=55pt]{geometry}
usepackage[style=authoryear,sorting=nyt,backend=biber]{biblatex}
    addbibresource{D:/Thesis/ref_thesis.bib}
begin{document}
Hallo Friends, it happens that parencite{hausman1} said X but parencite{athey} said Y.
printbibliography
end{document}

One Answer

The line 37 in the message refers to line 37 in biblatex.sty, which is (in version 3.15a)

RequirePackage{pdftexcmds}[2018/01/30]

and thus requests at least version 2018/01/30 of the pdftexcmds package.

Your system only has a slightly older version v0.26 from 2018/01/21 of pdftexcmds, so you get this warning.

You may want to consider updating your system (How do I update my TeX distribution?). If you are using a MikTeX system make sure to run the updater in Admin and User mode (How should one maintain and update a MiKTeX installation?).


This is not a general incompatibility between biblatex and XeLaTeX. It is an incompatibility between your old version of pdftexcmds and your newer version of biblatex.
