Federico,<br /><br />Thanks for your reply.&nbsp; I did build a recipe for a tar.gz source archive previously, which worked.&nbsp; But for the RPM I felt like I was missing something.&nbsp; Meanwhile, my multilib build for core-image-base is failing with the error below.&nbsp; This is without any custom recipes.&nbsp; I am not sure what to about this missing manifest file.&nbsp; I thought perhaps it was SDK related so I tried running <strong>bitbake core-image-base -c populate_sdk</strong>... but got a similar error.&nbsp; &nbsp;If I knew the root cause of this error, I might be able to fix it.&nbsp; But it seems that unless I've setup local.conf incorrectly, doing multilib should just work out of the box.&nbsp; Note that I successfully built<strong> core-image-base</strong> WITHOUT multilib configured in my local.conf.&nbsp; Simply adding the multilib config entries causes this error (local.conf attached).<br /><br />
