In addition Hrabans note.... When using tikz, don't use filenames with spaces. not: picture test.tex, better: picture-test.tex Building may work, so possibly not your error, but some text about ....pgf may appear in the PDF and empty files (here eg pictures) maybe created. bye, Martin On Wed, 2019-11-27 at 15:42 +0000, Ursula Hermann wrote:

The control sequence at the end of the top line of your error message was never \def'ed. You can just continue as I'll forget about whatever was undefined.
