[yocto] Build only 32 bit packages using multilib in a packagegroup for 64 bit machine

[Gaurav Vohra]

Hello,

I need to use multilib feature in yocto to build some applications which
are part of a packagegroup recipe as only 32 bit.

I can use command to  create 32 bit packages from this packagegroup which
works,.

# bitbake lib32-packagegroup-name.bb

But the packages in this packagegroup are still building as 64 bit when i
am trying to build image

bitbake core-sato-image.bb

Configuration done

in local.conf :

MACHINE = "qemux86-64"
require conf/multilib.conf
MULTILIBS = "multilib:lib32"
DEFAULTTUNE_virtclass-multilib-lib32 = "x86"

In image recipe replaced

IMAGE_INSTALL += "packagegroup-name"

to

IMAGE_INSTALL += "lib32-packagegroup-name"
Are these changes sufficient ?

Thanks gaurav
