bug#23641: emacs-25.0.94 build feedback

[Nelson H. F. Beebe]

I'm pleased to report that I've successfully built and installed the
latest emacs-25.0.94 test release on at least 65 flavors of Unix in my
test lab of more than 80 such systems.

However, on FreeBSD 11 x86-64, I ran into an issue.  Configuring
selects -lgio in src/Makefile, but that library has a problem on that
system: it refers to a symbol sendmmsg@FBSD_1.4 that is not defined in
any of the 3492 libraries installed on my system.  Even a forced
reinstallation of the -lgio library did not resolve the missing
symbol.

I made numerous unsuccessful attempts with various --without-XXX
options at configure time to try to eliminate the reference to -lgio,
but all failed.

I then examined configure.ac, where it appears that -lgio has to do
with glib, but could still not see what library options are forcing
the inclusion of -lgio.

I finally succeeded in building the new emacs with

	./configure --without-all --with-x && gmake all

Thanks, that is good to know.

It could be gfilenotify.  Try "--without-file-notification" or
"--with-file-notification='kqueue'" configure options.

Other suspects might be GTK and librsvg.

It could be more efficient if you post the summary of configured
options displayed by 'configure' at the end of its run.

Thanks.

Looks like librsvg-2 is the one that pulls in libgio.  Did you try
using --with-rsvg=no ?

Then this is the list of other suspects:

  imagemagick
  dbus
  gconf

I think you need to disable all of them (and rsvg as well) to get rid
of libgio.

Fine with me.

Thanks.

Does this include GNU/Linux variants?  If so, it is a mistake to call
them "flavors of Unix".  Remember, GNU's Not Unix !

[Nelson H. F. Beebe]

I wrote  about a build problem of emacs-25.0.94 on FreeBSD 11

I therefore tried this:

	./configure --with-{rsvg,dbus,gconf,imagemagick}=no && make

That led to a successful build!

Compared to my earlier reported successful build using --without-all,
the newly-built emacs has 62 shared libraries, whereas the previous
one had only 30.  I have therefore installed the new build.

It might be useful to document the dependence of -lgio on those four
packages:

	rsvg dbus gconf imagemagick

because that dependence is not obvious.  Alternatively, add a
configure-time --without-gio option that suppresses those four
packages.

I don't view this as high priority, because the FreeBSD 11 package
system is clearly in error when installation of a library (-lgio) does
not install all of its dependents.

Tomorrow, I'll try a similar build on HardenedBSD 11, a new VM that I
have just finished configuring:

I added this problem and its solution to etc/PROBLEMS.  Thanks.
