Subject: Questioning FILESOVERRIDES implied precedence in setting FILESPATH...
Date: Mon, 01 Dec 2014 01:00:32 -0500	[thread overview]
Message-ID: <547C0400.3010706@mindchasers.com> (raw)

Hi,

In poky master, FILESOVERRIDES is constructed as follows:

"${TRANSLATED_TARGET_ARCH}:${MACHINEOVERRIDES}:${DISTROOVERRIDES}"

For my current build, I get:

FILESOVERRIDES="powerpc:custom-machine:e500v2:qoriq-ppc:poky"

FILESPATH is built by calling base_set_filespath(), which is in 
utils.bbclass

This function constructs FILESPATH in such a way that the distro folder 
("poky") comes before the other overrides ( precedence is applied right 
to left using FILESOVERRIDES )

I see that there was a patch to reverse the ordering back in Oct of 2013 
(0bd63125c3b44) to make sure MACHINE overrides had precedence over 
platform specific overrides.  However, I'm wondering if the intent was 
to have the distro override both.  This doesn't make sense to me, so 
please clarify whether this is correct.  If it is, please explain why 
distro gets a higher precedence over machine.

Thanks,

Bob
