Hello,

there's a bug originated in  Gentoos bugzilla:

--- Comment #2 from Ulrich Müller <ulm <at> gentoo.org> ---
I can reproduce the problem with your USE flag settings. Both the 20150331 and
20150430 snapshots (the latter in my local overlay only) still compile fine,
whereas the 20150531 snapshot fails. Emacs from git master (as of today) also
fails with your USE flags.

Git bisecting shows that the breakage originates from the cairo branch:

   dddcc0e78452f2186c132823a33a174d2596ba33 is the first bad commit

       Add cairo drawing.


Can you please report the bug upstream? There is little we could do here at the
distro level.

If I may summarise:

./configure --with-cairo --without-xft

fails with undefined reference to ftfont_driver in ftcrfont.c.

Perhaps this is simply not a sensible set of configure options to use.

I would also suggest that Gentoo stop enabling --with-cairo,
and that the --with-cairo option perhaps be labelled experimental.

Maybe configure should take care of this, and enable cairo only under
the condition that xft is enabled too?

There is a similar problem with --with-cairo --without-png, by the
way. When linking temacs:
image.o:(.data+0x90): undefined reference to `png_load'

In fact, our whole app-editors/emacs-vcs package is experimental.
We usually reveal any upstream configure options as USE flags.
(After all, this is not an experimental branch, but git master.)

Of course, I can mask the cairo flag in addition, if you think that's
appropriate.

The culprit seems to be this condition around line 5645 of image.c:

  #if defined HAVE_PNG && !defined HAVE_NS

It should say this instead, I think:

  #if (defined HAVE_PNG && !defined HAVE_NS) || defined USE_CAIRO

But I cannot test that.

This change makes it compile for me.

Thanks, I pushed it.

Dependency on libXft for the cairo build was removed on master by the
commit 5f4e8e2e088.  Closing the bug.
