I'm very new to LaTeX and keep getting "Undefined Control Sequence" with the very first line of my attempt to test creating my own .sty package. Here's the code:

\setmainfont[Ligatures=TeX]{EB Garamond 12}

The error is in line 1. I've retyped the command faithfully from examples and even copied it straight, but same error. I noticed that the 'X' in "NeedsTeXFormat" needs to be capitalized. I just can't figure out what's going wrong.

  • Are you actually running latex? Show the complete log-file. – Ulrike Fischer Nov 9 '18 at 12:24

    Make sure you are not actually trying to compile the sty file itself. That won't work. – Steven B. Segletes Nov 9 '18 at 12:25

    the only purpose of the \NeedsTeXFormat{LaTeX2e} command is to generate an error if the file is used with a format other than LaTeX2e, so most likely you are using plain TeX rather than LaTeX. (pdftex command rather than pdflatex) – David Carlisle Nov 9 '18 at 12:43

    Are you trying to run TeX on the .sty file? – egreg Nov 9 '18 at 13:40
