I can offer only limited help with this one. texinfo/emacs support is now provided by a separate project. Please see the file README.emacs. Since I don't use either texinfo or emacs I am unclear on whether it is relevant that the gnuplot build system itself no longer provides a working makeinfo recipe. I had the impression that the separate "gnuplot-mode" project make this unnecessary, but I could be wrong about that.

My inclination is to simply say "we no longer support generation of an info file". Nevertheless if there is a simple fix to make it work I'd be happy to apply it. Was this working for you in gnuplot version 5.0? If so someone can probably bisect the introduction of a problem. If it hasn't worked since version 4.something, I'm dubious.

[Antonio Rojas]

Yes, this worked in 5.0 and it got broken with
https://github.com/gnuplot/gnuplot/commit/3795c91f

(sorry for using the guthib mirror, but I didn't want to learn cvs just to bisect this)

But since you say this is not maintained anymore, perhaps it's not worth fixing - as it will get broken again sooner or later without testing.

[Ethan Merritt]

Huh. That change was contributed by the group that maintains Japanese language documentation for gnuplot. I suppose it worked for them, but may not have been tested sufficiently on the English docs :-) Or maybe the Japanese version doesn't actually have any bulleted lists so the code was not exercised?

If you have a fix it I'd be happy to update the copy in CVS. Otherwise I will depend on contributions from elsewhere.

[Hans-Bernhard Broeker]

Sorry I didn't see this earlier to fix it.

The problem was already much smaller than seen in the above error message. The only remaining issue were some lines using # line tags without a blank after them, when the text begins with a b. That's indistinguishable from a #b tag, so clearly wrong.
