3 # This script is used to configure the linux kernel.
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.
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
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.
19 # Portions of this script were borrowed from the original Configure
22 # William Roadcap was the original author of Menuconfig.

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.
29 # 180697 Bernhard Kaindl (bkaindl@netway.at) - added the needed support
30 # for string options. They are handled like the int and hex options.
32 # 081297 Pavel Machek (pavel@atrey.karlin.mff.cuni.cz) - better error
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
40 # 101297 Michael Chastain (mec@shout.net) - remove sound driver cruft.
42 # 221297 Michael Chastain (mec@shout.net) - make define_bool actually
43 # define its arguments so that later tests on them work right.
45 # 160198 Michael Chastain (mec@shout.net) - fix bug with 'c' command
46 # (complement existing value) when used on virgin uninitialized variables.
48 # 090398 Axel Boldt (boldt@math.ucsb.edu) - allow for empty lines in help
51 # 12 Dec 1998, Michael Elizabeth Chastain (mec@shout.net)
52 # Remove a /tmp security hole in get_def (also makes it faster).

891 There seems to be a problem with the lxdialog companion utility which is
892 built prior to running Menuconfig. Usually this is an indicator that you
893 have upgraded/downgraded your ncurses libraries and did not remove the
894 old ncurses header file(s) in /usr/include or /usr/include/ncurses.
896 It is VERY important that you have only one set of ncurses header files
897 and that those files are properly version matched to the ncurses libraries
898 installed on your machine.
900 You may also need to rebuild lxdialog. This can be done by moving to
901 the /usr/src/linux/scripts/lxdialog directory and issuing the
902 "make clean all" command.
904 If you have verified that your ncurses install is correct, you may email
905 the maintainer <mec@shout.net> or post a message to
906 <linux-kernel@vger.kernel.org> for additional assistance.
