not working with current TL

[tweh]

Hi,

I know this is a quite bad title for the issue but I have no idea what the reason is. It seems like unicode-math is broken with a current TeX Live (I guess due to some changes in L3).

The following MWE won’t compile.

% !TeX program = xelatex
\documentclass{article}
\usepackage{unicode-math}
\begin{document}
Test
\end{document}

I’m using an up-to-date TeX Live 2017 and get several errors about undefined control sequences, e.g. \g__um_named_ranges_seq or \__um_log:nx.

no problem with my up-to-date TL2017

That’s strange … I can’t even get a file list … However I checked manually and the versions are the same as yours and tlmgr doesn’t show any updates at the moment. And as far as I can tell there’s nothing in my user texmf tree that can have an effect on this.

I attach the log file of this MWE

% !TeX program = xelatex
\listfiles
\documentclass{article}
\usepackage{unicode-math}
\begin{document}
Test
\end{document}

log file: um-bug.log

It seems that you have put unicode-math-xetex.sty in your working directory, but this file is not up-to-date and may not be compatible with the current unicode-math.

[hvoss49]

You are using a local file:

`(./unicode-math-xetex.sty

should also be

(/usr/local/texlive/2017/texmf-dist/tex/latex/unicode-math/unicode-math-xetex.sty

Damn … that’s the problem when using a cluttered temp folder for tests … thanks!
