Hi Ishaan,
Thanks for your patch.
We get a warning about this new recipe during the build:
WARNING: lib32-memory-control-1.0-r0 do_unpack: lib32-memory-control: the
directory ${UNPACKDIR}/${BP}
(/srv/pokybuild/yocto-worker/qemux86-world-alt/build/build/tmp/work/x86-pokymllib32-linux/lib32-memory-control/1.0/sources/memory-control-1.0)
pointed to by the S variable doesn't exist - please set S within the recipe to
point to where the source has been unpacked to
https://autobuilder.yoctoproject.org/valkyrie/#/builders/17/builds/3970
https://autobuilder.yoctoproject.org/valkyrie/#/builders/25/builds/4125
Can you make sure everything is correct?
Thanks,
Mathieu
