General ⇒ Warning: etexcmds could not find \expanded

[fduffy]

Hello,

I am a new user of the forum so I apologise if I have posted this question in the wrong section. I am getting a warning when I run pdflatex on the following tex file.

Code: Select all

documentclass[a4paper,10pt]{article}
usepackage[pdftex]{hyperref}
begin{document}
\section{Introduction}
Hello.
end{document}

The warning that I get is:

Package: infwarerr 2007/09/09 v1.2 Providing info/warning/message (HO)

and the relevant log entry is:

Package etexcmds Info: Could not find \expanded.
(etexcmds) That can mean that you are not using pdfTeX 1.50 or
(etexcmds) that some package has redefined \expanded.
(etexcmds) In the latter case, load this package earlier.

I am using pdfTeX, Version 3.1415926-1.40.9 (MiKTeX 2.7). As the log message states, I am not using pdfTeX 1.50 so I presume that this is why I am getting the warning (I do not have enough knowledge of the topic to look at the etexcmds and hyperref definition files to see exactly why the warning is appearing).

The same warning appears in numerous log files that I have looked at on various forums. My question is: does this warning imply that I have an error somewhere in my MiKTeX installation and can I do anything to remove it?

Any help with this would be much appreciated.
Thanks,
Francis.

No. \expanded is a new "primitive" which will be added to pdfTeX at version 1.50. The current release of pdfTeX is 1.40.9, and so does not have \expanded. The etexcmds package knows that \expanded will appear one day, so it looks for it. (There are low-level reasons why \expanded is useful, but it should not make too much difference to you.)

There is no warning message at all. The "Package: infwarerr 2007/09/09 v1.2 Providing info/warning/message (HO)" line is just the banner for the infwarerr package, and the message concerning \expanded is an informational message, not a warning. Warnings always appear on the terminal and contain the word "Warning".

Hi,

Thanks very much for your prompt replies.
I just wanted to make sure that I was not ignoring something important.

Have a good day,
Francis.
