3# This script is used to configure BusyBox.
4#
5# It was inspired by a desire to not have to hit <enter> 9 million times
6# or startup the X server just to change a single kernel parameter.
7#
8# This script attempts to parse the configuration files, which are
9# scattered throughout the kernel source tree, and creates a temporary
10# set of mini scripts which are in turn used to create nested menus and
11# radiolists.
12#
13# It uses a very modified/mutilated version of the "dialog" utility
14# written by Savio Lam (lam836@cs.cuhk.hk). Savio is not responsible
15# for this script or the version of dialog used by this script.
16# Please do not contact him with questions. The official version of
17# dialog is available at sunsite.unc.edu or a sunsite mirror.
18#
19# Portions of this script were borrowed from the original Configure
20# script.
21#
22# William Roadcap was the original author of Menuconfig.
23# Michael Elizabeth Chastain (mec@shout.net) is the current maintainer.
24#
25# 070497 Bernhard Kaindl (bkaindl@netway.at) - get default values for
26# new bool, tristate and dep_tristate parameters from the defconfig file.
27# new configuration parameters are marked with '(NEW)' as in make config.
28#
29# 180697 Bernhard Kaindl (bkaindl@netway.at) - added the needed support
30# for string options. They are handled like the int and hex options.
31#
32# 081297 Pavel Machek (pavel@atrey.karlin.mff.cuni.cz) - better error
33# handling
34#
35# 131197 Michael Chastain (mec@shout.net) - output all lines for a
36# choice list, not just the selected one. This makes the output
37# the same as Configure output, which is important for smart config
38# dependencies.
39#
40# 101297 Michael Chastain (mec@shout.net) - remove sound driver cruft.
41#
42# 221297 Michael Chastain (mec@shout.net) - make define_bool actually
43# define its arguments so that later tests on them work right.
44#
45# 160198 Michael Chastain (mec@shout.net) - fix bug with 'c' command
46# (complement existing value) when used on virgin uninitialized variables.
47#
48# 090398 Axel Boldt (boldt@math.ucsb.edu) - allow for empty lines in help
49# texts.
50#
51# 12 Dec 1998, Michael Elizabeth Chastain (mec@shout.net)
52# Remove a /tmp security hole in get_def (also makes it faster).
53# Give uninitialized variables canonical values rather than null value.
54# Change a lot of places to call set_x_info uniformly.
55# Take out message about preparing version (old sound driver cruft).
56#
57# 13 Dec 1998, Riley H Williams <rhw@memalpha.cx>
58# When an error occurs, actually display the error message as well as
59# our comments thereon.
60#
61# 31 Dec 1998, Michael Elizabeth Chastain (mec@shout.net)
62# Fix mod_bool to honor $CONFIG_MODULES.
63# Fix dep_tristate to call define_bool when dependency is "n".
64#
65# 02 January 1999, Michael Elizabeth Chastain (mec@shout.net)
66# Blow away lxdialog.scrltmp on entry to activate_menu. This protects
67# against people who use commands like ' ' to select menus.
68#
69# 24 January 1999, Michael Elizabeth Chastain, <mec@shout.net>
70# - Improve the exit message (Jeff Ronne).
71#
72# 06 July 1999, Andrzej M. Krzysztofowicz, <ankry@mif.pg.gda.pl>
73# - Support for multiple conditions in dep_tristate().
74# - Implemented new functions: define_tristate(), define_int(), define_hex(),
75# define_string(), dep_bool().
76#
77# 22 October 2001, Erik Andersen <andersee@debian.org>
78# - Adjusted for busybox (modified hard coded kernel specific paths,
79# and everything to do with modules (tristates, modbools, etc).

755There seems to be a problem with the lxdialog companion utility which is
756built prior to running Menuconfig. Usually this is an indicator that you
757have upgraded/downgraded your ncurses libraries and did not remove the
758old ncurses header file(s) in /usr/include or /usr/include/ncurses.
759
760It is VERY important that you have only one set of ncurses header files
761and that those files are properly version matched to the ncurses libraries
762installed on your machine.
763
764You may also need to rebuild lxdialog. This can be done by moving to
765the /usr/src/linux/scripts/lxdialog directory and issuing the
766"make clean all" command.
767
768If you have verified that your ncurses install is correct, you may email
769the maintainer <andersen@codepoet.org> or post a message to
770<busybox@oss.lineo.com> for additional assistance.
