[Buildroot] [PATCH v2 1/1] package/weston: replace autotools with meson

[Buildroot] [PATCH v2 1/1] package/weston: replace autotools with meson

[James Hilliard]

The autotools build system is in the process of being deprecated and
replaced with meson for weston.

We need to enable pango when building demo clients since it is required
by meson.

The dbus option in autotools is replaced with launcher-logind in meson.

We need to explicitly set the image-webp option to avoid failures when
building without webp.

Replaced WESTON_NATIVE_BACKEND with backend-default in meson.

Signed-off-by: James Hilliard <james.hilliard1@gmail.com>

---
Changes v1 -> v2:
  - Require both systemd and dbus for launcher-logind
  - Move dmabuf-v4l out of egl/gl block
  - Update imx-gpu-g2d requirement block

[Buildroot] [PATCH v2 1/1] package/weston: replace autotools with meson

Why is this option added as a dependency. I understand about the other
depends on and the select on pango, but I don't understand this
BR2_PACKAGE_MESA3D_OPENGL_EGL dependency.

If you want to say "build this when headers >= 3.8", then it should be:

ifeq ($(BR2_TOOLCHAIN_HEADERS_AT_LEAST_3_8),y)

> +	-Dbackend-default=fbdev

I'm still not happy with the -Dbackend-default handling. Indeed, if you
enable fbdev, and drm and x11, and xwayland, you are going to pass 4
-Dbackend-default options.

Is this backend-default option mandatory ? Perhaps we can leave it
undefined, and simply have the user select the backend at runtime ? I
suppose if there is only backend, weston is smart enough at runtime to
use that one ?

Could you test with this -Dbackend-default option, making a runtime
test ?

Thanks!

Thomas

I think that was due to this:

Yeah, I agree, I've been trying to think of a better way to handle this.

I'm not sure, maybe a kconfig choice menu is needed for selecting a default?

I'll try and experiment.
