The source tree can contain lots of uninteresting data like tag or cscope files, packaging which slows down make rpm needlessly. It can also break the build, if the tree contains an unrelated file named *.spec. The downside of this change is that new subdirectories have to be added to the KBUILD_ALLDIRS variable in the top-level Makefile. The upside is that the behavior is more predictable.

# Makefile for the different targets used to generate full packages of a kernel
|
|
# It uses the generic clean infrastructure of kbuild
|
|
|
|
# RPM target
|
|
# ---------------------------------------------------------------------------
|
|
# The rpm target generates two rpm files:
|
|
# /usr/src/packages/SRPMS/kernel-2.6.7rc2-1.src.rpm
|
|
# /usr/src/packages/RPMS/i386/kernel-2.6.7rc2-1.<arch>.rpm
|
|
# The src.rpm files includes all source for the kernel being built
|
|
# The <arch>.rpm includes kernel configuration, modules etc.
|
|
#
|
|
# Process to create the rpm files
|
|
# a) clean the kernel
|
|
# b) Generate .spec file
|
|
# c) Build a tar ball, using symlink to make kernel version
|
|
# first entry in the path
|
|
# d) and pack the result to a tar.gz file
|
|
# e) generate the rpm files, based on kernel.spec
|
|
# - Use /. to avoid tar packing just the symlink
|
|
|
|
# Note that the rpm-pkg target cannot be used with KBUILD_OUTPUT,
|
|
# but the binrpm-pkg target can; for some reason O= gets ignored.
|
|
|
|
# Do we have rpmbuild, otherwise fall back to the older rpm
