Subject: [PATCHv2] Fix 'make rpm' when CONFIG_LOCALVERSION_AUTO=y and using SCM tree
Date: Thu, 19 Feb 2009 23:45:31 -0800	[thread overview]
Message-ID: <20090220074531.GF8151@localhost.localdomain> (raw)

Updated patch with Sam's fixes as per this discussion:
http://lkml.org/lkml/2009/2/15/18

Running 'make rpm' fails when CONFIG_LOCALVERSION_AUTO=y and using a kernel
source tree under SCM.  This is due to KERNELRELEASE being different when the
initial make is run and when make is run from rpmbuild.

mkspec creates kernel.spec using KERNELRELEASE:

<mkspec>
echo "%files"
echo '%defattr (-, root, root)'
echo "%dir /lib/modules"
echo "/lib/modules/$KERNELRELEASE"
echo "/lib/firmware"
echo "/boot/*"
echo ""
</mkspec>

When CONFIG_LOCALVERSION_AUTO=y scripts/setlocalversion is called and grabs any
additional version info from SCM.  Next, the srctree is tarred up and SCM
information is excluded.

rpmbuild reruns make and in the process generates a new
include/config/kernel.release and thus a new KERNELRELEASE.  However this time
the SCM information is gone so KERNELRELEASE no longer has the additional
version information.  When "make modules_install" runs, it uses the new
KERNELRELEASE value to determine where to install the modules.  This conflicts
with where the spec file assumes they are going because of the mis-matching
KERNELRELEASE versions.

I have tested this patch on git -tip, Linus' git tree, and the kernel.org tar
files, both with and without CONFIG_LOCALVERSION_AUTO=y.
