10 # 070497 Bernhard Kaindl (bkaindl@netway.at) - get default values for
11 # new bool, tristate and dep_tristate parameters from the defconfig file.
12 # new configuration parameters are marked with '(NEW)' as in make config.
14 # 180697 Bernhard Kaindl (bkaindl@netway.at) - added the needed support
15 # for string options. They are handled like the int and hex options.
17 # 081297 Pavel Machek (pavel@atrey.karlin.mff.cuni.cz) - better error
20 # 131197 Michael Chastain (mec@shout.net) - output all lines for a
21 # choice list, not just the selected one. This makes the output
22 # the same as Configure output, which is important for smart config
25 # 101297 Michael Chastain (mec@shout.net) - remove sound driver cruft.
27 # 221297 Michael Chastain (mec@shout.net) - make define_bool actually
28 # define its arguments so that later tests on them work right.
30 # 160198 Michael Chastain (mec@shout.net) - fix bug with 'c' command
31 # (complement existing value) when used on virgin uninitialized variables.
33 # 090398 Axel Boldt (boldt@math.ucsb.edu) - allow for empty lines in help
36 # 12 Dec 1998, Michael Elizabeth Chastain (mec@shout.net)
37 # Remove a /tmp security hole in get_def (also makes it faster).
38 # Give uninitialized variables canonical values rather than null value.
39 # Change a lot of places to call set_x_info uniformly.
40 # Take out message about preparing version (old sound driver cruft).

43 # When an error occurs, actually display the error message as well as
44 # our comments thereon.
46 # 31 Dec 1998, Michael Elizabeth Chastain (mec@shout.net)
47 # Fix mod_bool to honor $CONFIG_MODULES.
48 # Fix dep_tristate to call define_bool when dependency is "n".

51 # Blow away lxdialog.scrltmp on entry to activate_menu. This protects
52 # against people who use commands like ' ' to select menus.
54 # 24 January 1999, Michael Elizabeth Chastain, <mec@shout.net>
55 # - Improve the exit message (Jeff Ronne).
57 # 06 July 1999, Andrzej M. Krzysztofowicz, <ankry@mif.pg.gda.pl>
58 # - Support for multiple conditions in dep_tristate().
59 # - Implemented new functions: define_tristate(), define_int(), define_hex(),
60 # define_string(), dep_bool().

880 There seems to be a problem with the lxdialog companion utility which is
881 built prior to running Menuconfig. Usually this is an indicator that you
882 have upgraded/downgraded your ncurses libraries and did not remove the
883 old ncurses header file(s) in /usr/include or /usr/include/ncurses.
885 It is VERY important that you have only one set of ncurses header files
886 and that those files are properly version matched to the ncurses libraries
887 installed on your machine.
889 You may also need to rebuild lxdialog. This can be done by moving to
890 the /usr/src/linux/scripts/lxdialog directory and issuing the
891 "make clean all" command.
893 If you have verified that your ncurses install is correct, you may email
894 the maintainer <asmax@videolan.org>.
