# Slackware build script for calf-ladspa

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

# 20211127 bkw: BUILD=2
# - rework README and slack-desc, remove mentions of JACK and DSSI.
# - move html docs to subdir.

# 20170706 bkw:
# - Patch source so it doesn't check for jack-audio-connection-kit or
#   fluidsynth. Previously they were required for the build to complete,
#   but the stuff that got built with support for them was being rm'ed
#   after make install (because the package only contains LADSPA plugins).
# - Remove jack-audio-connection-kit and fluidsynth from REQUIRES.
# - Add patch to support -current's gcc7. For now, it's commented out
#   in the SlackBuild, since 14.2 doesn't need it.

# 20151105 bkw:
# - Renamed to calf-ladspa. The main calf build is now for calf-0.0.60,
#   which lacks LADSPA support. Removed LV2 and standalone support, use
#   calf for that instead. Removed DSSI support, because I don't
#   think anyone's using it, and because it's non-trivial to install
#   the gui support files anywhere other than /usr/share/calf, which
#   would step on the main calf package.

# 20141030 bkw:
# Finally getting around to submitting this, there have been no code
# changes upstream since 20140308.

# 20140308 bkw:
# - Switched to falkTX's KXStudio fork of CALF. falkTX doesn't do release
#   tarballs, so this is a git checkout from 20140308.
# - Added capability stuff.
