The comment was about the "Tizen on Yocto" recipes, not
Yocto. The
recipes have issues that you don't see when building recipes
manually
written for Yocto.
These recipes get converted from .spec files to .bb files
based on the
build configuration for x86. All architecture specific tweaks
in Tizen
get lost at that point and have to be added back manually to the
generated .bb files.
The spec2yocto conversion tool also does not have enough
information
available in the .spec files about dependencies (is a tool
needed or
something to link against?) and has to use heuristics, which
fail in
some cases when doing cross-compilation.
It looks like you have skipped my announce of successful building
of "Tizen IVI on Yocto" for ARM-based board DRA7XX. And as far as
I recall Leon have used few my recipes changes in his buildings.
It was the reason why I expected than Leon would understand me :)
Vitaly, yes I used parts of your recipes. Actually similar fixes
exist for the recipes in the fork of Tizen:Common for Raspberry Pi
2 which is maintained by Samsung Open Source Group.
In my opinion the main problem at the moment is that building
Tizen:Common or Tizen IVI using Yocto for ARM does not work out of
the box.
But, is building Tizen IVI for ARM using GBS working now? About half
of year ago it doesn't work and amount of efforts to made it working
was much-more bigger than insignificant efforts to made "Tizen IVI on
Yocto" for ARM working.
I haven't built any Tizen profiles with GBS recently. I think that the
daily images of Tizen:Common are built using GBS. New Tizen:Common
images for ARM are available so I assume it should be working:
http://download.tizen.org/snapshots/tizen/common/latest/images/
As far as I remember your changes related to DRA7XX were pushed
into a sandbox. Do you plan to merge them with tizen-distro upstream
As far as I understand Tizen maintainers they will do it themselves
when they will be interesting in it.
I doubt that the maintainers have the resources to do it right now.
According to git log there have been almost no changes for several
months in the upstream of "Tizen on Yocto" for Tizen:Common and Tizen IVI.
Best regards,
Leon
and to support both ARM & Intel machines with the same recipes?
I do not know. I'm deallocated from Tizen activity so I do not have
any ideas about it.
With best regards,
Thanks,
Leon
