# Slackware build script for kitty-bin

# Written by B. Watson (urchlay@slackware.uk)

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

# Notes:

# This exists because building kitty from source requires the latest
# bleeding-edge google-go-lang, newer than we have in the repo, and
# because Go is just too fast-moving a target for me. At any given
# time, it's likely that the latest binaries will work before we're
# able to build our own. This means kitty-bin will probably be a bit
# newer version than the regular kitty build.

# Since upstream provides a 64-bit ARM binary bundle, this script can
# create an aarch64 package. I don't use ARM and haven't tested it.

# 20230715 bkw: update for v0.29.0.

# 20230630 bkw: BUILD=2
# - fix a major boo-boo: /usr/lib was being overwritten with a symlink
#   to lib64. this broke on multilib, badly.
