11# Maintainer: John Mylchreest <johnm@gentoo.org> 18# "kernel config" in this file means:
12# Copyright 2004 Gentoo Linux 19# The .config of the currently installed sources is used as the first

14# Please direct your bugs to the current eclass maintainer :) 22# Before using any of the config-handling functions in this eclass, you must
23# ensure that one of the following functions has been called (in order of

19# Env Var Option Description 33# @ECLASS-VARIABLE: KERNEL_DIR
20# KERNEL_DIR <string> The directory containing kernel the target kernel 34# @DESCRIPTION:
21# sources. 35# A string containing the directory of the target kernel sources. The default value is
36# "/usr/src/linux"
37
38# @ECLASS-VARIABLE: CONFIG_CHECK
39# @DESCRIPTION:
22# CONFIG_CHECK <string> a list of .config options to check for before 40# A string containing a list of .config options to check for before

53# In general, most checks should be non-fatal. The only time fatal checks should
54# be used is for building kernel modules or cases that a compile will fail
55# without the option.
56#
57# This is to allow usage of binary kernels, and minimal systems without kernel
58# sources.
