# This script is used to configure BusyBox.
|

|
#
|
|||
|
# It was inspired by a desire to not have to hit <enter> 9 million times
|
|||
|
# or startup the X server just to change a single kernel parameter.
|
|||
|
#
|
|||
|
# This script attempts to parse the configuration files, which are
|
|||
|
# scattered throughout the kernel source tree, and creates a temporary
|
|||
|
# set of mini scripts which are in turn used to create nested menus and
|
|||
|
# radiolists.
|
|||
|
#
|
|||
|
# It uses a very modified/mutilated version of the "dialog" utility
|
|||
|
# written by Savio Lam (lam836@cs.cuhk.hk). Savio is not responsible
|
|||
|
# for this script or the version of dialog used by this script.
|
|||
|
# Please do not contact him with questions. The official version of
|
|||
|
# dialog is available at sunsite.unc.edu or a sunsite mirror.

# 070497 Bernhard Kaindl (bkaindl@netway.at) - get default values for

# new configuration parameters are marked with '(NEW)' as in make config.

|
# 131197 Michael Chastain (mec@shout.net) - output all lines for a

|

|

|
# 160198 Michael Chastain (mec@shout.net) - fix bug with 'c' command

# (complement existing value) when used on virgin uninitialized variables.

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