Thank you. I tested emacs-26.1-x86_64 with depos for 12 hours and see no
problem.

I tried configuring this new Emacs like

./configure '--with-xwidgets'

on a somewhat old (but still supported) Ubuntu 14.04 LTS release but 
encounter this error:

configure:12632: checking for WEBKIT
configure:12639: $PKG_CONFIG --exists --print-errors "$WEBKIT_MODULES"
Package webkit2gtk-4.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `webkit2gtk-4.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'webkit2gtk-4.0' found

There was no mention in the release notes that versions still in heavy 
use were being abandoned and that Emacs could only be built on 
brand-new Linux releases.

This system comes with libwebkitgtk-3.0-dev.  It is prohibitive to 
attempt to install anything newer since the whole software stack would 
need to be replaced.

Thatʼs a somewhat unfair statement: emacs 26 works fine on Ubuntu
14.04 as far as I know, itʼs just the xwidgets support that doesnʼt,
so in no way is there any 'abandonment' going on.

The change should perhaps have been mentioned in NEWS, but I believe
xwidgets is still classed as experimental, so perhaps not.

Emacs moved to the WebKit2 API in October of 2016. Iʼm assuming there
were good reasons for not trying to support the older API as well. Iʼm
also assuming there were good reasons for nobody running Ubuntu 14.04
to attempt to build emacs with xwidget support since then.

Initially there was an attempt to support both gtk2 and gtk3, but it was
difficult, so the gtk2 support was abandoned. It is not impossible in
principle though, just not doable with the existing resources. Also, the
state of emacs webkit support should not reflect badly on the rest of emacs.

I removed the 'xwidgets' request and then emacs compiles and runs 
fine.  This is good since I must use this Ubuntu version for the 
moment.

The hard configure error which does not indicate to the user what 
corrective action should be taken (other than looking in config.log) 
is not good.

If there are specific package versions required, then they should be 
listed in the installation documentation.

That'd be nice to have, but I'm not sure we have the resources to
provide an accurate list and keep it up to date.  All the other
projects I've built never provide such info, you have to "discover"
that by building and getting error messages that tell you what minimal
version is required.

But if someone wants to arrange such a list (in INSTALL, I think?), it
would be very welcome.

Developers should be cognizant of the packages they are requiring to 
be used.

It would be very helpful if configure specified what it is 
specifically looking for, and includes what it needs in the error 
message.

It seems that the new emacs silently quit last night while the screen 
was locked.  I may need to retreat to the previous release (25.3).

Something else I notice is that when I open a file which is in a 
Mercurial repository, the /usr/bin/hg program crashes and I get an 
Ubuntu crash report.  The Ubuntu crash report screen does not allow me 
to copy text from it, but the command executed which crashed starts 
with '/usr/bin/python /usr/bin/hg log -r . -l1 -template ...'.  This 
does not happen with emacs-25.3.  The crash is due to use of a None 
value.  The version of Mercurial provided by this Ubuntu release is 
2.8.2.

It’s not so easy. A library can be packaged under one name in Debian
and a slightly different name in Red Hat, or distributed as one vs.
multiple packages, or carried by one distribution but not the other.
So, the error message that lists a missing library or header is pretty
much the best you can get without delving into those differences.

The task of maintaining a configure script is definitely not easy. 
The benefits of making the configure script as user-friendly as 
possible is that then more users are using the latest version rather 
than a stale version provided by their operating system distribution.

In this case the configure.ac developer explicitly entered a 
pkg-config package name (including its major version) and so it was a 
developer decision to produce a specific pkg-config package name but 
used an indistinct generic meaningless name ("WEBKIT") in configure 
output that the user sees, as well as the terminal error message.

The project is able to maintain 1.1 million lines of lisp code and 
293k lines of ANSI C code which are presumably mostly correct, so it 
should be possible to suitably maintain the 5k lines of configure.ac 
code as so that ordinary end users are able to compile emacs as well.

For Debian-based OS-es, the easiest way to build and run Emacs is:

sudo apt-get build-dep emacs24
git clone git://git.savannah.gnu.org/emacs.git
cd emacs
make
./src/emacs &

It'll pull inn all libraries you need.  Perhaps we should just make a
note of that in a file like README.DEBIANISH?

(The "emacs24" may be "emacs25" on very fresh OS-es.)

We are -- for about 5 seconds after we modify configure.ac to require
a specific version of a certain package.  Thereafter, the required
versions are recorded in configury, and nowhere else.  For example:

  WEBKIT_REQUIRED=2.12
  WEBKIT_MODULES="webkit2gtk-4.0 >= $WEBKIT_REQUIRED"

This is quite self-explanatory, right?

The problem is to collect all these requirements, express them in
human-readable form, and then keep that up-to-date whenever the
configury changes.  That's a non-trivial manual work.

Btw, the info you are looking for is generally available on the
Internet.  I like to use http://www.linuxfromscratch.org in such
cases, in particular see

  http://www.linuxfromscratch.org/blfs/view/svn/postlfs/emacs.html

(It still doesn't show Emacs 26, but it probably will soon.)

It does.  In your case, it didn't find the package-config file for the
relevant version, so it only could tell you that webkit2gtk-4.0 is not
installed.  Once you install it, if its version is older than the one
required, you'd see a message saying it looked for version X.Y.Z, but
didn't find it.

I suggest to look in the system message log to see what happened.  If
it crashed, please consider submitting a bug report.

Please submit a separate bug report using "M-x report-emacs-bug", and
please include in the report the relevant details, such as the hg
command issued by Emacs and the Python backtrace.

Thanks.

I've now (belatedly) added the notice about this change to NEWS, which
will show in Emacs 26.2.
