Re: help wanted for implementing GdkGLContext on Windows and MacOS X



hi;

I'd like to point out that this is a build-time requirement for
libepoxy only: if the app does not use GLX on the Apple X server, then
the GLX code is never even loaded.

it'd be nice to have a libepoxy build that does not require X11 on
MacOS, but that would make it harder to have applications linking
against libepoxy run on the X server on that platform. whether or not
that is a long term strategy is a discussion worth having with Eric.

ciao,
 Emmanuele.

Yeah, this is an unfortunate bug with libepoxy right now. There's a PR on
GitHub if you want to see if that fixes it.

All we can do is pressure Eric Anholt to merge it at this point.

hi all;

I posted this on my blog, which is syndacated on Planet GNOME, but I
thought about trying to reach out to more people by using the GTK+
mailing list as well.

GTK+ 3.16 will have OpenGL support out of the box — at least on X11 and
Wayland.

if you are using GTK+ 3.x on Windows and/or MacOS X, or if you're
using external libraries like GtkGLExt and GtkGLArea with GTK+ 2.x or
3.x, then I'm asking you to help out with patches and testing the
OpenGL support in the master branch of GTK+. we'd really like to have
OpenGL support working on all the major backends in GDK by the time we
release GTK+ 3.16.0, next February.


I've started trying to build GTK master on OSX; looks like libepoxy is now
a dependency of GDK, and libepoxy in turn needs X11.h. How hard is that
dependency? It seems to me that I shouldn't need X11 for the Quartz backend.
