* user-friendly(?) build system, based on linux Menuconfig script. 

  Just run ./menuconfig and ./build-vlc (or just ./build-vlc)
  It's actually a wrapper which calls configure, but only a small number
  of vlc functionalities has been implemented at the moment.
  Please try it however ;)
  (you must have libncurses-dev installed)

/*
* Changes by Clifford Wolf (god@clifford.at)
*
* [ 1998-06-13 ]
*
* *) A bugfix for the Page-Down problem
*
* *) Formerly when I used Page Down and Page Up, the cursor would be set
* to the first position in the menu box. Now lxdialog is a bit
* smarter and works more like other menu systems (just have a look at
* it).
*
* *) Formerly if I selected something my scrolling would be broken because
* lxdialog is re-invoked by the Menuconfig shell script, can't
* remember the last scrolling position, and just sets it so that the
* cursor is at the bottom of the box. Now it writes the temporary file
* lxdialog.scrltmp which contains this information. The file is
* deleted by lxdialog if the user leaves a submenu or enters a new
* one, but it would be nice if Menuconfig could make another "rm -f"
* just to be sure. Just try it out - you will recognise a difference!
*
* [ 1998-06-14 ]
*
* *) Now lxdialog is crash-safe against broken "lxdialog.scrltmp" files
* and menus change their size on the fly.
*
* *) If for some reason the last scrolling position is not saved by
* lxdialog, it sets the scrolling so that the selected item is in the
* middle of the menu box, not at the bottom.
*
* 02 January 1999, Michael Elizabeth Chastain (mec@shout.net)
* Reset 'scroll' to 0 if the value from lxdialog.scrltmp is bogus.
* This fixes a bug in Menuconfig where using ' ' to descend into menus
* would leave mis-synchronized lxdialog.scrltmp files lying around,
* fscanf would read in 'scroll', and eventually that value would get used.

#-----------------------------------------------------------------
# William Roadcap was the original author of Menuconfig.
# Michael Elizabeth Chastain (mec@shout.net) is the current maintainer.
#
# 070497 Bernhard Kaindl (bkaindl@netway.at) - get default values for
# new bool, tristate and dep_tristate parameters from the defconfig file.
# new configuration parameters are marked with '(NEW)' as in make config.
#
# 180697 Bernhard Kaindl (bkaindl@netway.at) - added the needed support
# for string options. They are handled like the int and hex options.
#
# 081297 Pavel Machek (pavel@atrey.karlin.mff.cuni.cz) - better error
# handling
#
# 131197 Michael Chastain (mec@shout.net) - output all lines for a
# choice list, not just the selected one. This makes the output
# the same as Configure output, which is important for smart config
# dependencies.
#
# 101297 Michael Chastain (mec@shout.net) - remove sound driver cruft.
#
# 221297 Michael Chastain (mec@shout.net) - make define_bool actually
# define its arguments so that later tests on them work right.
#
# 160198 Michael Chastain (mec@shout.net) - fix bug with 'c' command
# (complement existing value) when used on virgin uninitialized variables.
#
# 090398 Axel Boldt (boldt@math.ucsb.edu) - allow for empty lines in help
# texts.
#
# 12 Dec 1998, Michael Elizabeth Chastain (mec@shout.net)
# Remove a /tmp security hole in get_def (also makes it faster).
# Give uninitialized variables canonical values rather than null value.
# Change a lot of places to call set_x_info uniformly.
# Take out message about preparing version (old sound driver cruft).
#
# 13 Dec 1998, Riley H Williams <Riley@Williams.Name>
# When an error occurs, actually display the error message as well as
# our comments thereon.
#
# 31 Dec 1998, Michael Elizabeth Chastain (mec@shout.net)
# Fix mod_bool to honor $CONFIG_MODULES.
# Fix dep_tristate to call define_bool when dependency is "n".
#
# 02 January 1999, Michael Elizabeth Chastain (mec@shout.net)
# Blow away lxdialog.scrltmp on entry to activate_menu. This protects
# against people who use commands like ' ' to select menus.
#
# 24 January 1999, Michael Elizabeth Chastain, <mec@shout.net>
# - Improve the exit message (Jeff Ronne).
#
# 06 July 1999, Andrzej M. Krzysztofowicz, <ankry@mif.pg.gda.pl>
# - Support for multiple conditions in dep_tristate().
# - Implemented new functions: define_tristate(), define_int(), define_hex(),
# define_string(), dep_bool().

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 <mec@shout.net> or post a message to
<linux-kernel@vger.kernel.org> for additional assistance.
