# Slackware build script for LÖVE (legacy 0.8 version)

# Written by Dugan Chen (thedoogster [at] gmail [dot] com)

# Modified for 0.8.0 legacy version by B. Watson (urchlay@slackware.uk)

# If you're packaging up a LÖVE game that needs this version (won't work
# with 0.9.x), make sure the shebang line in the .love file says:
#  #!/usr/bin/env love-0.8.0
# See mari0.SlackBuild for an example.

# 20241107 bkw: BUILD=3, use lua51 (because this won't build with luajit-2.1.x)
# 20241018 bkw: BUILD=2, REQUIRES=luajit instead of lua.
# 20210903 bkw: fix build for current/pre15.
