[meta-raspberrypi] meta-ivi & meta-raspberrypi

[meta-raspberrypi] meta-ivi & meta-raspberrypi

[Oliver]

Hello

I have been working building together the meta-raspberrypi & the meta-ivi layers.
I have been stuck with configuration/compilation of weston(from mata-ivi layer):

1)

You can check the intial thread http://lists.genivi.org/pipermail/genivi-meta-ivi/2015-April/000508.html


egl provided by userlad is not detected as the *.pc files are not deployed
Someone has faced similar problems:

   http://git.buildroot.net/buildroot/commit/?id=2282b93f4248a32de84805456efa352f69b28624

2)
With this I am able to reach the do_compile stage but there are errors related to the undefined type

PFNEGLQUERYWAYLANDBUFFERWL
Hacked this one forcing the inclusion of <weston-egl-ext.h> :-S


3)
At linking time the next trouble is:

/home/oliver/raspberry/build-rpi-ivi/tmp/sysroots/i686-linux/usr/libexec/arm-poky-linux-gnueabi/gcc/arm-poky-linux-gnueabi/4.9.1/ld: cannot find -lwayland-egl

IIRC this lib is provided by mesa-gl, but in my build, mesa is configured(--disable-egl (is this ok being provided by userlad?)) which might be the reason why libwayland-egl is not getting deployed in the image?

Any correction to my statements or hint to go further would be appreciated

Best Regards & thanks for your time

Oliver

Hi Oliver,

I was looking at wayland/weston last year.  I can't remember exactly
where I was at with it I am afraid, but I think I had it building and
have pushed some of the code I was playing with to GitHub

I think this was related to the .pc issue

https://github.com/DynamicDevices/meta-raspberrypi/commit/491dd14585efdb52378a57fa6ddacb1f15065257

And this was what I was doing with weston. Looks like I was disabling EGL.

https://github.com/DynamicDevices/meta-raspberrypi/commit/c657f69deb57035fc43319dd7d41745c17d7d6e1

Sorry I can't be more help but perhaps there's something in there that
might be of use.

Regards,

Alex

I was able to build weston/wayland with meta-raspberrypi, for
the Tizen distro:
	http://blogs.s-osg.org/bringing-tizen-to-a-raspberry-pi-2-near-you/

I had to apply a few patches to make it work on both Tizen and
meta-raspberrypi. The forks are at:
	http://git.s-osg.org/

The current version there is actually disabling EGL. Enabling
it seems to be possible, but we're still trying to make it work
(it compiles fine, though, so I think we're close).

Once done, my plan is to work on porting the patches back to
meta-raspberrypi (and tizen-distro).

The egl-enabled version (with doesn't run, currently), is at the
"devel" branch at both git trees.

I hope that helps.

Regards,
Mauro

Great news Mauro. If you need anybody to test out your patches, when
ready, please give me a shout.
