HOWTO

# GNU Ncurses 6.2 (ncurses = new curses)
# ===============
# Slackware 13.37, 14.0, 14.1, 14.2: ncurses 5.9

# Many other pieces of software can be removed before you install a new
# version with little to no ill-effects, 'make uninstall' the old one, 'make
# install' the new one.  ncurses is so widely used that you may not be able
# to get away with that, without breaking a bunch of things.  Below we blow
# away files that may be left over from old source-installed versions of
# ncurses, ass|u|me'ing that you still have libncurses in /lib or /lib64
# from Slackware's aaa_elflibs|aaa_libraries package to keep things working
# that use it.  If you are not comfortable with that, skip the cleanup part
# before 'make install' below, then either leave it all there and hope for
# the best, or manually clean up files after the new version is installed -
# look for a date that is other than today.
#
# Loads of console programs like dialog, lynx, mc, mutt, ncftp, joe, vim,
# etc. use ncurses and even things like the Dropbox daemon do, so running
# something like:
#   lsof /lib*/libncurses.* /usr/lib*/libncurses.*
# is not a bad idea, to find out what running programs are using it.

# The home page for Ncurses is https://invisible-island.net/ncurses/
# but the GNU page for it is here:
# https://invisible-island.net/ncurses/

# If you have any trouble downloading Ncurses from gnu.org, you can
# also get it here:
# ftp://ftp.invisible-island.net/ncurses/
# https://invisible-mirror.net/archives/ncurses/

# Release notes

# Prerequisites:
# pkg-config
# ctags

# Due to the number of patches, create a directory for the ncurses tarball
# and patches, move the tarball and patches into it (if you previously had
# any of them):
mkdir -p -m 0700 ~/installed/ncurses
( cd ~/installed
  mv -f ncurses-6.2.tar.gz ncurses-*.patch.gz    ncurses-*-patch.sh.bz2 ncurses/ 2> /dev/null )

# Get it

# [ Note: When I did this, one patch to ANNOUNCEMENT was .rej, changing it
#   from a 6.1 version to 6.2, but that is just a text doc file, so just
