# Slackware build script for snes9x

# Licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.

# 20240814 bkw: update for v1.63.
# Had to update Vulkan-Headers to get it to compile. Did not update
# Spirv-Headers or glslang. If this causes anyone any problems, please
# let me know.

# 20230418 bkw: BUILD=2, make portaudio optional + autodetected.

# 20230410 bkw: update for 1.62.3.
# Most of the work needed for this update was done by M.Dinslage,
# to whom I owe thanks. I updated the man page, and added the
# non-GUI binary plus a man page for it.

# For older change-comments, see ChangeLog.old (it was getting too long
# to keep in the script).

# snes9x_libretro-info originally came from:

# Renamed .info => .info.txt 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.
