I am using pdflatex on a fresh (and current) MikTex 2.9 install with the following MWE:


Pdflatex throws the error:

Package: pdfbase 2017/03/23 v0.14 driver independent access to low-level PDF fe

! Undefined control sequence.
<argument> \luatexversion 
l.924 }

I have read the other posts containing the offending control sequence, especially this one but the solutions offered there didn't help in my case.

This problem might have arisen with a recent MikTex update. I have now completely uninstalled, redownloaded, reinstalled and updates MikTex -- with no success.


Update the media9 package to version 0.81 as of 2017/07/24 which provides file pdfbase.sty loaded by pkg animate.

Quickfix until the next package update of MiKTeX: Put the current pdfbase.sty into the working directory (directory with your document source).

A recent LaTeX3 kernel update made fixing media9 (and other packages) necessary. Related: What does greedy \bool_if:n(TF) mean?

  • The MikTex package manager only offers me version 0.80 by now. I will recheck within the next few days. – David Woitkowski Jul 25 '17 at 13:01
  • @David For a quickfix see edit. – AlexG Jul 25 '17 at 13:06
