# Slackware build script for klick

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

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

# 20240908 bkw:
# - update for v0.14.2, new homepage (github).
# - remove LIBLO=no since builds fail without it and it's already
#   listed in REQUIRES.

# 20211129 bkw: BUILD=2
# - fix build on -current. see Makefile.
# - autodetect rubberband and liblo.
# - enable terminal support.
# - add missing klick.pod (source for the man page).
# - dynamic slack-desc.
# - include klick2ardour.py, in case someone has a use for it.

# 20170620 bkw: add -fpermissive to cflags, for -current's gcc7.
