From cdfd6216ac49fc7622d563d671a5b6511492827d Mon Sep 17 00:00:00 2001 From: Jussi Kukkonen Date: Tue, 21 Jun 2016 15:11:39 +0300 Subject: [PATCH] Add --disable-opengl configure option --disable-opengl will remove the dependency on libepoxy and on the OpenGL APIs. This is useful for those who want to keep using gtk+3 without the "opengl" distro feature. GtkGLArea is still part of the API (it just doesn't work) even when OpenGL is disabled. GdkX11GLContext was removed from the Gtk API completely: that object exposes GL API elements so it had to be at the very least modified. The patch is _not_ great from a maintenance point of view and modifying the library API is also a fairly nasty thing to do. Next long term release (4.0) will require alternative solutions as it actually will depend on OpenGL.
