[Buildroot] [PATCH 1/4] package/efl: add OpenGL/OpenGLES support

Wed Sep 7 21:08:40 UTC 2016


Allow to enable graphic acceleration using OpenGL or OpenGLES with efl
libraries.

The full OpenGL option depend on X11, because full OpenGL means GLX,
which means X11. Also select efl xlib support when full OpenGL is
selected.

Enable OpenGL ES when EGL API is enabled, otherwise the build fail with
this error:
configure: error: OpenGL ES requires EGL, please add --enable-egl to your configure options to switch to EGL + OpenGL ES.

With the upcomming Wayland support in EFL Buildroot packaging,
OpenGL ES support is recommended.

v8: Select efl xlib support with the full opengl support
    is selected. (Yann E.Morin)
    Ref: http://lists.busybox.net/pipermail/buildroot/2015-December/146646.html
v6: Rename OpenGL options (Yann E.Morin)
    Only full OpenGL support depends on X11.
