# Slackware build script for rakarrack

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

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

# 20241206 bkw:
# - update for last git commit, 0.6.2+20150813_a620840.
# - add some patches, including one that fixes a segfault on startup.
#   apparently, the previous version has segfaulted on startup ever
#   since Slackware 15.0 came out, and nobody mentioned it (and I
#   haven't used rakarrack in a while either).
# - add SSE=no option.
# - touch up README and slack-desc (mention guitar).

# 20211205 bkw: BUILD=3, new-style icons.
# 20140114 bkw: add 64-bit distortion fix and setcap stuff.
# 20151126 bkw: fix build on -current, preparing for 14.2.

# Note: Please don't remove this from the repo just because it's
# no longer maintained upstream. It's useful, it works, it makes
# interesting sounds, and some of us actually use it.

# provided for building on a box *with* SSE/SSE2, for deployment on a
# box that lacks it.
# Setting SSE to a non-empty value in configure's env is required, to
