# Slackware build script for sonic-visualiser

# Written by B. Watson (yalhcru@gmail.com)

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

# 20170312 bkw:
# - update for 3.0.1
# - parallel build seems OK, remove -j1 (again)
# - 3.0.1 requires a bleeding-edge capnproto (newer than the latest
#   release) so build a static one to link with. When capnproto.SlackBuild
#   gets updated past 0.5.3, this stuff can go away. The static capnproto
#   is used whether or not capnproto is installed on the system, and it's
#   not installed as part of the sonic-visualiser package.
# - add note to README about pulse and portaudio failures. I don't know
#   what's wrong yet, but jack-audio-connection-kit remains a hard dep
#   unless/until I figure it out.
# - upstream fixed the .desktop, remove my code that fixed the old one.
# - stop the unit tests from spamming /root

# 20160819 bkw:
# - parallel build is still broken, revert to -j1

# 20160806 bkw:
# - updated to 2.5, which means adding a qt5 dep.
# - fix parallel build.
# - according to INSTALL.txt, jack-audio-connection-kit is optional,
#   so I was going to remove it from REQUIRES. I tried building without it,
#   but the build failed, so it remains a hard dep for now.

# 20140913 bkw:
# - finally updated (from 1.9 to 2.3)
# - add man page
# - use png icon rather than svg
# - add MIME types for desktop integration
# - add realtime capabilities

# Grrr. Upstream requires a git version of capnproto, newer than the
# latest release. They *really* should bundle it, or at least mention it
# in their README or INSTALL.txt, if they're going to depend on bleeding
# edge stuff... the only way to understand what's going on here is to
# actually read the comments in configure.ac. We have to build a static
# capnproto and force sonic-visualiser to use it.
