# Slackware build script for open-invaders
# Written by B. Watson (yalhcru@gmail.com)
# Licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.
# This isn't really that great a game. The developer spent a lot
# of time on bling-ey graphics and sound, but it's missing some of
# the basic gameplay elements that made Space Invaders a classic:
# the enemies don't speed up during the level as you kill them,
# and there are no UFOs (at least, not on the first 7 levels; maybe
# later?). To be fair, the README says it's "still in development"
# and not finished (maybe the author planned to add that stuff later,
# but development stopped in 2007 or so).
# I patched the game a bit to make it less annoying to play (made the
# intro screens skippable).
# The part of VERSION after the _ is the Debian patchlevel. They've
# done a good bit of patching and bugfixing to keep this usable on a
# modern system.

# The -Dnullptr=0 is a bit of a dirty hack. We use debian's
# gcc6.patch, which fixes "return false" in a function returning
# a pointer... but replaces 'false' with 'nullptr'. In our gcc 11,
# we need std=gnu++98 to get it to build, which means nullptr isn't
# defined. So define it. Not sure why C++11 needs yet another keyword
# that's just an alias for 0 (it already had NULL). This kind of
# stuff is why I never code in C++: it's a moving target, it has been
# since day 1, and the C++ standards gurus make sure it keeps moving
# perpetually.
# Need this for dumb.h on 32-bit, it does no harm on 64-bit. See
