The following header file is indeed missing on my system, and it seems it can be provided by media-libs/gst-plugins-bad when built with USE="egl"

I'm test building with media-libs/gst-plugins-bad built with 'egl' support. I'm sorry I cannot provide complete build log at the moment

Small update, now with media-libs/gst-plugins-bad rebuilt with USE="egl", net-libs/webkit-gtk-2.18.1 builds fine for me.

net-libs/webkit-gtk-2.18.1 (X egl geolocation gstreamer introspection jit libnotify opengl spell webgl)
media-libs/gst-plugins-bad-1.12.3 (X abi_x86_64 bzip2 egl gtk introspection nls opengl orc)

[Comment 2 Joakim Tjernlund 2017-10-23 14:34:49 UTC]

me too, same build error and same fix(gst-bad egl) for me

[Comment 3 Fred Krogh 2017-10-23 16:14:36 UTC]

I too went from failure to success by adding egl to the use flags for gst-plugins-bad.
Thanks for the suggestion.

    net-libs/webkit-gtk: USE=gstreamer,egl requires gst-plugins-bad[egl] now
    
    If EGL is enabled, then the gstreamer code (only compiled with USE=gstreamer) will
    want to include gstreamer egl headers, in addition to gst gl headers

As seen, I've added the necessary depend. But now we have the problem of webkit-gtk having IUSE=+egl, while gst-plugins-bad doesn't. Need to think how to approach that, before I feel comfortable stabilizing webkit-gtk-2.18.1 for security.. overnight ideas welcome (I need to hit the bed for now)

[Comment 6 Mart Raudsepp 2017-10-26 12:59:35 UTC]

I've default enabled USE=egl,opengl on gst-plugins-bad to accommodate. Hope that doesn't have too much fallout.
webkit-gtk needing this will probably go stable due to security before the gst-plugins-bad version with IUSE default changes does; but the stabilization of that gst-plugins-bad will probably be filed later today as well, just it won't have a security high priority.
