You are building without libotf?

Heh, I was just about to report the same build problem on Solaris 11.4,
which has HarfBuzz but apparently lacks libotf.

It helps, thanks.  I needed to make a similar change in a few other
places, at least for building on Solaris.  I've attached the patch I
ended up with.

I still can't get a clean build, because of

    Checking /export/home/kupfer/src/emacs-git/lisp/leim/quail/japanese.el ...

I got the same failure building master, so it's not related to HarfBuzz.
I'll follow up about this second failure when I get some time; maybe
next week.

cheers,

Thanks, it seems to build now without errors.
I still get a few warnings though:

Yes, my configure output contains

  Does Emacs use -lotf?                                   no

Sure, now I get two different warnings:
