compilation of emacs 25.1 with xwidgets on os x

compilation of emacs 25.1 with xwidgets on os x

Hello,

I’m trying to compile emacs 25.1 with xwidgets on os x, and I’m facing
some issues. I’ve found out that I need the configure option
`--without-ns' for the option `--with-gtk-toolkit=gtk3' to stick, but I
cannot get my local installation of webkitgtk to be recognized: the
version provided by homebrew only seems to provide webkitgtk-4.0, which
is not accepted by emacs (that seems to require webkitgtk-3.0).

Is it possible to compile emacs 25.1 with xwidgets support on os x?

Thanks a lot for this great release,

Alan Schmitt

Hi Alan,

I'm not sure, but have you tried specifying the version,

--with-x-toolkit=gtk4

I hope that works.

There’s a separate issue with trying to get xwidgets on Emacs via
Homebrew, which is that the build of GTK+3 supplied by Homebrew does not
include the X11 backend, which is required by xwidgets.

Thanks for the information. As soon as I get over the webkitgtk hurdle,
I’ll look at a patch to include that option in the gtk+3 brew package.

X11 was deliberately removed from the whole GTK dependency tree, so unfortunately such a patch won't be accepted (the rationale is the poor user experience that X11 provides on macOS).

Ouch. What is the recommended way to get xwidgets to work on os x then?

GTK+3 will just have to be installed manually, outside of Homebrew, right?

I guess it’s the only way. Thank you for the suggestion, I’ll give it a
try once I have figured the webkitgtk issue.

Or depending on how familiar you are with Homebrew you could create your
own formula and host it in a "tap":

Thank you for the suggestion, but there is no gtk4 backend yet. If I
understand this blog post
https://blogs.igalia.com/carlosgc/2014/08/01/webkitgtk-2-5-1-good-bye-webkit1/
the pgk-config file to use is webkit2gtk-4.0 for versions after 2.5.1,
which is consistent with what I’m seeing (I have that pkg-config on my
system).

What version of webkitgtk is recommended to build emacs? I have 2.10.9
here.

Thanks,

Alan
