# For:         audacity
# Descr:       multi-track audio editor and recorder
# URL:         https://audacityteam.org
# Build needs: 
# Needs:       jack2, ladspa_sdk, libsbsms, lilv, lv2, portaudio, portmidi,
#              portsmf, serd, sord, soundtouch, soxr, sratom, suil,

# Changelog:   
# 1.3.12-1:    12/Apr/2010 by Eric Hameleers <alien@slackware.com>
#              * Initial build.
# 1.3.12-2:    31/may/2010 by Eric Hameleers <alien@slackware.com>
#              * Rebuild for Slackware 13.1
# 2.2.2-1:     22/Feb/2019 by Eric Hameleers <alien@slackware.com>
#              * Overdue update.
# 2.3.3-1:     27/nov/2019 by Eric Hameleers <alien@slackware.com>
#              * Update.
# 2.4.1-1:     28/may/2020 by Eric Hameleers <alien@slackware.com>
#              * Update. Do not use the new 'cmake' configuration yet,
#                because it is way too buggy.
# 2.4.2-1:     27/jun/2020 by Eric Hameleers <alien@slackware.com>
#              * Update. Use cmake, and an internal patched wxGTK3.
# 2.4.2-2:     09/oct/2020 by Eric Hameleers <alien@slackware.com>
#              * Added X-DAW category to desktop file.
# 3.0.0-1:     18/mar/2021 by Eric Hameleers <alien@slackware.com>
#              * Update.
# 3.0.2-1:     22/apr/2021 by Eric Hameleers <alien@slackware.com>
#              * Update.
# 3.0.2-2:     19/aug/2021 by Eric Hameleers <alien@slackware.com>
#              * Fix 'internal database error' when saving a project on exit.
# 3.1.3-1:     18/sep/2022 by Eric Hameleers <alien@slackware.com>
#              * Update. Don't use conan, instead provide all the external
#                dependencies ourselves.
#                Audacity on Linux can now use vanilla wxWidgets >= 3.1.3,
#                as long as wx is provided as dynamic libraries.
#                Also, portsmf version 234 (static library this time) is
#                mandatory, since audacity won't link against newer releases.
# 3.2.1-1:     10/oct/2022 by Eric Hameleers <alien@slackware.com>
#              * Update.
# 3.2.2-1:     18/dec/2022 by Eric Hameleers <alien@slackware.com>
#              * Update.
# 
# Run 'sh audacity.SlackBuild' to build a Slackware package.
# The package (.t?z) and .txt file as well as build logs are created in /tmp .
# Install the package using 'installpkg' or 'upgradepkg --install-new'.
