I'm trying to switch to XeTeX, because I would love to have a better integration of postscript code (and pstricks) in my PDF files. However, I did not succeed completely, one error is left and present in the MWE I have added below:

! Missing number, treated as zero.


A number should have been here; I inserted `0'.



\usepackage{polyglossia} % LuaLaTeX replacement for babel




I have to include some German text in my otherwise completely English book. That's why I have used \foreignlanguage which has never been a problem with pdfLaTeX.

  • It might be preferable to write \textgerman{ABC} instead. – Thorsten Donig Feb 22 '14 at 15:33
  • Gives the same error as \foreignlanguage does. – MrD Feb 22 '14 at 15:47
  • I don't get any errors. – karlkoeller Feb 22 '14 at 15:50

I found the solution myself and will describe what I did in case somebody else runs into the same problem:

Installing TeXLive "on top" of the old one will not work. The error persists. One has to delete /usrlocal/texlive/2013/* and /usrlocal/texlive/texmf-local/* manually. After that, the error no longer occurs after performing a new installation.

However, I cannot explain what might have caused the problem in the first place, as the reinstallation was successful using the same version of install-tl.

  • You probably had a language.dat file in texmf-local. – egreg Feb 23 '14 at 13:17
