# Slackware build script for calf

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

# 20260728 bkw: update for v0.90.9.
# - Upstream switched to cmake.
# - 0.90.9 supposedly supports WANT_SSE=OFF, but this causes the build
#   to fail, so SSE is always enabled.

# 20211204 bkw: BUILD=3, move html docs to subdir.
# 20200117 bkw: demote lash from required to optional dependency.
# 20191208 bkw: update for v0.90.3.

# 20180709 bkw:
# - Update to latest release (less than a day old).
# - Use correct upstream homepage.

# 20170622 bkw:
# - Update to latest git. It's been a long time since the last release.
# - Actually make the SSE=yes option work (d'oh!)

# 20170301 bkw: use long-format github URL, no more $VERSION.tar.gz

# 20151106 bkw:
# Switch to -master and upgrade to v0.0.60. No more LADSPA or DSSI
# support (upstream dropped it). But if you need LADSPA, there's a
# separate calf-ladspa build now. If there's a popular demand for
# DSSI, I'll add it to calf-ladspa, not here.
# fluidsynth is now required, because the build fails without it, even
# though it's listed as experimental and there's a --disable-experimental
# option. Since it's required anyway, might as well --enable-experimental.

# 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.
