! Undefined control sequence. <argument> \ExplFileName

[Stephan Hennig]

Hi,

compiling the following file via

lualatex --interaction=batchmode mbsp

fails with an up-to-date TL2011:

\listfiles
\documentclass{article}
\usepackage{fontspec}
\begin{document}
A
\end{document}


The command

tlmgr show l3kernel l3packages l3experimental

shows for all packages

cat-version: SVN 2607
cat-date: 2011-08-17 22:57:44 +0200

Best regards,

and I'll forget about whatever was undefined.

Hi Stephan,

Sorry for the inconvenience. I just updated my tl2011 installation and I don't have any problems myself (I've attached the \listfiles output below). Is there any chance you have an older version of the expl3 packages installed locally?

Now that I think of it, note that the LaTeX3 code has been re-arranged recently and an older copy may still be present in your distribution's texmf tree (what used to be inside expl3/ is now in l3kernel/); I'm not entirely sure under what situations this could happen but I think some others have also had this issue.

Hope this helps,
Will

Not locally, but ...

That will be the issue. Make sure 'expl3' and 'xpackages' are removed.

Yes, the file compiles fine now. I'll send a note to the TL list.
Thanks all for looking into this!

Hello Stephan,

We really need to see all of you log file. The latest release versions
of the LaTeX3 material all work fine, and define \ExplFileName, etx. I
suspect that something is being loaded 'out of place', but without the
full log can't tell.

Sorry for not sending the full log file in the first place. I have
suspected it's a problem with the recent reorganization in l3 packages.
But since you can't reproduce it ... perhaps it's a Windows specific TL
packaging error (Windows 7 Prof. x64)?

Anyway, here's the log. Unfortunately, batchmode doesn't give me a full
package list.

Stephan Hennig
