xwidget on master under opensuse

xwidget on master under opensuse

[Stephen Berman]

I just updated and rebuilt from master for the first time since the
commits making xwidget use the webkit2 API, and discovered that I cannot
build Emacs with xwidget because I don't have a recent enough
libwebkit2.  Moreover, it appears that such a version is not available
for my OS, opensuse: 2.12 is required but 2.10 is the most recent
version I've found.  So it appears I have to build and install webkit2
from source to use xwidget on current Emacs from master.  Is this
correct and is it straightforward?  Or does someone know of a recent
enough version for opensuse?  Thanks,

Steve Berman

Would it be possible to for you to try to lower the requirements in the
configury, and report the results here? TIA.

I changed the WEBKIT_REQUIRED test in configure from 2.12 to 2.6.6,
which was the version I had from opensuse, and the build failed due to an
undefined reference to `JSValueIsArray'.  Then I installed an unofficial
build of 2.10.4 that is available from one of the opensuse repositories,
changed configure again and rebuilt emacs, this time successfully.  I
started emacs -Q, invoked xwidget-webkit-browse-url and visited a
website, and it appears to work fine.  There are, however, a slew of
messages in the shell where I started emacs:

(emacs:13002): Gdk-WARNING **: gdkwindow-x11.c:5584 drawable is not a native X11 window

Variants of the latter message (each with a different hex number) was
displayed hundreds of times.
