Hi,

I have recently tried to use the MULTILIB feature of Yocto Dunfell on a iMX8 platform and I was not able anymore to build the SDK as soon as I add the lib32-libusb1 in the package list.
Libusb1 has a dependency on wayland-protocols and it seems Yocto can find any suitable version of lib32-wayland-protocols during do_populate_sdk.

Here is the error I got:

test-image-1.0-r0 do_populate_sdk: Manifest /workdir/oe-core/build/tmp/sstate-control/manifest-x86_64_x86_64-nativesdk-lib32-wayland-protocols.package_write_ipk not found in 1388_imx8x aarch64-mx8 armv7at2hf-neon armv7ahf-neon armv7at2hf-vfp armv7ahf-vfp armv6thf-vfp armv6hf-vfp armv5tehf-vfp armv5ehf-vfp armv5thf-vfp armv5hf-vfp allarch x86_64_x86_64-nativesdk (variant 'lib32')?

ERROR: Task (/workdir/oe-core/build/../layers/meta-eagle/recipes-images/images/test-image.bb:do_populate_sdk) failed with exit code '1'

However I can found "manifest-armv7at2hf-neon-mx8-lib32-wayland" in the sstate-control folder.

I'm a bit lost in that piece of code, but my understanding is that the fsl-dynamic-packagearch.bbclass is appending an additional ARCH based on the current ARCH + the "MACHINE_SOCARCH_SUFFIX" suffix, but doesn't manage the MULTILIB architectures.

I have draft a patch to manage all ARCH coming from MULTILIB that seems to fix the problem but I would appreciate any comments (is it the right way to fix the problem, is the patch correct ...)
