Subject[BK PATCH 2/3] Teach kbuild to pull files from BK repository
From
Date
# This is a BitKeeper generated patch for the following project:
# Project Name: Linux kernel tree
# This patch format is intended for GNU patch command version 2.5 or higher.
# This patch includes the following deltas:
# ChangeSet 1.1505 -> 1.1506
# scripts/kconfig/lkc.h 1.5 -> 1.6
# Makefile 1.440 -> 1.441
# scripts/kconfig/zconf.l 1.7 -> 1.8
# scripts/kconfig/lex.zconf.c_shipped 1.7 -> 1.8
# scripts/kconfig/Makefile 1.11 -> 1.12
# (new) -> 1.1 scripts/depkconfig
# (new) -> 1.1 scripts/kconfig/listkconfigs.c
#
# The following is the BitKeeper ChangeSet Log
# --------------------------------------------
# 03/12/04 dave@thedillows.org 1.1506
# Teach the kbuild system how to retrieve the Kconfig files from
# the repository. This involves modifying the kconfig lexer/parser
# to give us a list of sourced Kconfig files so that we can tell
# make about the dependencies. Then is just a matter of makeing sure
# that make will extract those files before they are needed in the
# build process.
# --------------------------------------------
