The "Release:" field of the spec file is determined based on the .version file. However, the .version file is not copied to the source tar file. So, when we build the kernel from the source package, the UTS_VERSION always indicates #1. This does not match with "rpm -q". The kernel UTS_VERSION and "rpm -q" do not agree for binrpm-pkg, either. Please note the kernel has already been built before the spec file is created. Currently, mkspec invokes mkversion. This script returns an incremented version. So, the "Release:" field of the spec file is greater than the version in the kernel by one. For the source package build (where .version file is missing), we can give KBUILD_BUILD_VERSION=%{release} to the build command. For the binary package build, we can simply read out the .version file because it contains the version number that was used for building the kernel image. We can remove scripts/mkversion because scripts/package/Makefile need not touch the .version file. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

# 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.
|
|
|
|
# Remove hyphens since they have special meaning in RPM filenames
