webkit with poky(yocto) on top of directfb and not X11

webkit with poky(yocto) on top of directfb and not X11

[Robert Berger]

Hi,

I'm trying to figure out how to get a webkit with yocto/poky built
without X11, but directfb instead.

Grepping through the poky tree that's what I see:

sato contains a webkit, which depends on gtk+, which runs on x11/clutter.

... but there is also a qt4-embedded package, which seems to run on top
of directfb and has a dependency with webkit.

Does this mean, that if I build/install qt4-embedded and kill the
X-server on a sato image that I'll have a webkit on top of directfb?

Is this supposed to be the right way to achieve webkit over directfb?

Please advise.

Regards,

I am also new to the DirectFB, some here is just preliminary thought for 
your referrence.

 From the dependency point of view, you want a webkit-fb which is 
depending on gtk+-fb which in turn is depending on DirectFB. so probably 
you need:
- a gtk-fb recipes. it can reuse current gtk+ recipe, but add directfb 
target, like EXTRA_OECONF += " --with-gdktarget=directfb "
- a webkit-fb recipe: it can reuse the current webkit-gtk recipe, but 
add directfb target: EXTRA_OECONF += " --with-target=directfb "

it is not related to qt4-embedded, so you don't need to add qt4-embedded.

I don't know that there's one "right" way - Ke has suggested a gtk+ based 
solution, but qt4-embedded should also work in the way you described, in that 
it will provide a webkit-based web browsing widget for your application that 
can be used without X.

In this scenario you would create a recipe for your application that would 
inherit from the qt4e bbclass, and then create a custom image that would 
install your application's package, and shared library dependencies will pull 
in the appropriate Qt4-embedded packages automatically. The finishing touch 
would be an init-script that started your application on boot.

(I guess it would be useful to document some of this Qt4 stuff in a little more 
depth at some point.)

Cheers,
Paul

I did not try it yet with yocto/poky, but last time we tried webkit over
gtk+ over directfb it turned out that what you suggest exists, but only
partially;)
If you are brave enough to build it you will find that there is actually
still a dependency on X11, which needs to be stubbed.

You might want to have a look here to see what I mean:

Hi,

You can find also in openembedded __nonworking__ recipes:

http://git.openembedded.org/cgit.cgi/openembedded/tree/recipes/nonworking/gtk+/gtk+-directfb_2.10.14.bb

So I guess this approach needs quite a bit of cooking and it's
questionable if and how the webkit plugin infrastructure will work.

Robert
