# Slackware build script for snes9x
# Written by B. Watson (yalhcru@gmail.com)
# Licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.
# 20181201 bkw:
# - update for 1.57.
# - disable OSS audio by default, add OSS=yes option.
# - autodetect RetroArch, add RETROARCH=yes|no option.
# - document the above in the README.
# - document PULSE=no io README.
# - stop including snes9x.conf.default in the docdir, since it's
# outdated and will cause snes9x to segfault if you try to use it!
# - since we now have 3 build options, make slack-desc show them.
# - add patch from upstream to speed up linking the libretro core if
# -jX is in MAKEFLAGS.
# - add patch fro upstream to stop segfaulting if the config file is
# missing the ScanlineIntensity variable. Means I can finaly remove
# the "you should delete your old config file" from the README.
# 20180730 bkw:
# - BUILD=2.
# - add libretro/RetroArch, thanks to orbea.
# - add --without-portaudio to configure args. snes9x runs about
# 1 frame/sec if I start it up with the sound driver set to portaudio,
# and I've gotten a report of it blasting high-volume white noise
# thru the speakers if you switch to portaudio while a ROM is already
# running. I can't see any reason to use it in favor of pulse, alsa,
# oss, or sdl audio.
# - don't extract windows, mac, old-school unix stuff from tarball.
# uses 50% less $TMP space.
# 20180623 bkw: update for 1.56.2.
# 20180611 bkw:
# - update for 1.56.1.
# - switch the UI from gtk3 to gtk2, as 14.2's gtk3 is too old.
# - add undocumented PULSE=no build option (in anticipation of 15.0's
# pure-alsa-system).
# - add SDL2 to REQUIRES. technically, it's not truly required: snes9x
# only uses SDL2 to support joysticks. playing with the keyboard/mouse
# would still work without it. 15.0 is coming soon, and will have SDL2
# in the core OS, so don't bother me about this decision.
# - update README, the snes9x_gtk build went away in 2010, no need to
# mention it now. also add notes about upgrading from 1.55.
# 20171221 bkw: use --without-system-zip to build bundled unzip, instead
# of adding minizip as a dependency.
# 20171213 bkw: update for 1.55.
# 20170302 bkw: use long-format github URL
# 20161015 bkw: update for 1.54.1. script has changed enough that it
# can't build 1.53 any more.

# Various patches, depending on the version we're building. Currently
# this script should work with 1.56.2 and 1.57. Anything older and you're
# on your own.
# For 1.56.2, libretro.diff fixes the libretro build, it's upstream's
# commits abb4b4c39 and a77b3b379b. Already included in 1.57.
# For 1.57 (and 1.56.2 I hope), fix_config_file_segfaults.diff is
# upstream's commit 5e9f068. libretro_lto_variable is 21d6275 (thanks
# to orbea for coding this one & sending it upstream, based on my vague
# idea). Future 1.57.x or 1.58 will include these already.
# At some point, this set of cases will be too complex for me to want to
# maintain & test it, and it'll go away (this script will only support
# the latest version, whatever that happens to be).

# RetroArch support, contributed by orbea (Hunter Sezen).
# Note that the source here is self-contained, there's no build-time
# dependency on RetroArch or libretro or such.
# snes9x_libretro-info originally came from:
# https://raw.githubusercontent.com/libretro/libretro-super/383f18fd7c36ffd5fe76ebac58e9e596dde67e66/dist/info/snes9x_libretro.info
# Renamed .info => -info to avoid confusing SBo tools that deal with
# SBo's .info files.
# 20181201 bkw: made this optional, auto-detected, and controllable
# via environment. It makes the build take 7x as long, no point wasting
# time building it if it's not wanted/needed.
