Does PCTeX have proper e-TeX support?

Postby mwrenfro » Fri Mar 11, 2011 11:17 pm

In trying to use the etoolbox package with PCTeX v6 (6.1, Build Fri Apr 16 13:29:46 2010), it looks like either PCTeX doesn't have e-TeX support, or etoolbox is checking for that support incorrectly. Since PCTeX didn't include etoolbox, or know how to get it from CTAN (or else I don't know how to fix it), I copied etoolbox.sty and etoolbox.def v2.1 from a TeX Live 2010 install into the same folder as the MWE below:

  1. \documentclass{article}
  2. \usepackage{etoolbox}
  3. \begin{document}
  4. Hello, world.
  5. \end{document}

Building this with PCTeX returns "! Package etoolbox Error: Not running under e-TeX." while building it with TeX Live 2010 works fine. Any ideas on how to narrow down the source of the problem?

perhaps post your .log file here as attachment, we could have a look at it.

I hadn't been keeping up with this thread, but I got an answer on the PCTeX forum within a few days.

This is the PCTeX thread. Short version of the fix:

To use e-TeX's extended mode, go to PCTeX's Typeset menu, select INITeX, select LaTeX, add an asterisk to the beginning of the macro file name (i.e. "*latex.ltx"), and click INITeX.

Now when you typeset with LaTeX, it will use e-TeX's extended mode.

I confirm that the steps, described above, solve the problem with PCTeX. It will also ask you for a number of files to download (which it requires in order to compile); this is ok.
In my case, it gave me an error :
"missing xargs.sty"

Just download it from: ... /xargs.sty

And put it in: (C:)...\PCTeX\PCTeXv6\texmf-dist\tex\latex

That's it!
