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. 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 and
to support both ARM & Intel machines with the same recipes?
Thanks,
Leon
