# Slackware build script for guitarix
# Written by Michales Michaloudes korgie@gmail.com

# Modified by B. Watson <yalhcru@gmail.com>:
# - Upgraded to guitarix2
# - Added man page
# - Added realtime capabilities
# - Make .desktop file validate
# - Add guitarix's README to /usr/doc

# 20130430 bkw:
# - Updated for 0.27.1
# - Replaced slack-desc with updated text from guitarix site
# - Added LV2 option

# 20150514 bkw:
# - Updated for 0.32.3
# - Fix some issues with the shared libs: they were being installed
#   to /usr/lib/ on 64-bit, and they were missing the +x bits.
# - Made LV2 option default to yes, since upstream is requiring lilv
#   even if --no-lv2 is used. Also, the lv2 plugins were being
#   installed to /usr/lib/ on 64-bit. Grr.
# - Upstream wants avahi by default. For now, hardcoded --no-avahi.

# 20151108 bkw:
# - Updated for 0.34.0
# - Added --disable-cxx11 to ./waf flags, as bluetooth.h uses the gcc
#   typeof() extension. Not sure if newer versions of bluez would have
#   this issue (but Slackware 14.1's bluez is pretty old by now).
# - Added patch from upstream git to allow building without webkitgtk.
#   The author added support for downloading presets, but didn't make
#   it optional in 0.34.0. Also added a couple of bugfix patches.
# - Support building 0.33.0 with VERSION=0.33.0 in the env.
# - Add SSE=no option.
# - Add WEBKIT=no option.
# - Remove LV2=no option from README (but not from script).

# Modified version released under the WTFPL, for details see
# http://www.wtfpl.net/txt/copying/

# causes Slack 14.1's old bluetooth.h to fail (it uses gcc extensions).
# Before 0.34.0, this option's not needed... and will cause an error if
# it's present. Also, our patches are for 0.34.0 and won't apply to
# 0.33.0. So:
