Error when compiling refcards (emacs-25 branch)

Error when compiling refcards (emacs-25 branch)

hi,

I get an error when compiling the polish refcard on emacs-25, both under
Debian Stable and Fedora 24.

On both systems I have texlive-full installed, which includes the MeX
package.

Here's the output:

    if ! kpsewhich -format=fmt mex > /dev/null && \
      ! pdfmex --version > /dev/null 2> /dev/null; then \
      echo "No mex format found."; false; \
    fi
    TEXINPUTS=".:" pdftex -output-format=pdf pl-refcard.tex
    This is pdfTeX, Version 3.14159265-2.6-1.40.16 (TeX Live 2016/dev) (preloaded format=mex)
     restricted \write18 enabled.
    entering extended mode
    (./pl-refcard.tex
    This is MeX  Version 1.05  18 XII 1993  (B. Jackowski & M. Ry\'cko)

    ) (./emacsver.tex) [2 columns per page] [1{/usr/share/texlive/texmf-dist/fonts/
    map/pdftex/updmap/pdftex.map}] [2] [3]
    ! MeX error: Illegal pair of characters  /r  occured.

                                                      \endgroup


This goes beyond my knowledge of LaTeX.

Cheers,
Nico

Please try again.

Compiling the refcards to PDF works, but I'm still facing an error for
the compilation to PostScript (I do have texlive-mex installed):

  $ make -C etc/refcards ps
  [...]
  if ! kpsewhich -format=fmt mex > /dev/null; then \
    echo "No mex format found."; false; \
  fi
  No mex format found.
  Makefile:236: recipe for target 'pl-refcard.dvi' failed

That's a different problem; I guess something is missing in your
installation.

I suggest to ask this on the appropriate TeX forum.  Sorry, I don't
know where that is.  Or maybe try on bug-texinfo@gnu.org, there are a
few guys there who know TeX well.

That was my first thought as well, but I have tried both on Fedora 25
and Debian 8, with the full TeXlive distribution installed, and I get
the exact same error.

I'll try that, thanks.

Have you tried calling the `mex` command directly, as per the following
patch?

Do we still need to support this?
