Makefile

# Makefile for the collaborate scripts
#
# Author: Brent Baccala
# Last updated: May 2024
#
# This makefile builds:
#    - the four BigBlueButton packages that need to be changed from a stock 2.4 BigBlueButton system
#       - bbb-html5 is needed for remote desktop support
#       - all four need to be changed for private IP address support, if we're running on a subnetted
#         private network (it works out of the box for a non-subnetted private network)
#       - it checks out my fork of the bigbluebutton repository and calls build/setup.sh for the four packages
#    - two BigBlueButton packages (bbb-vnc-collaborate and freesoft-gnome-desktop) that I build with the old BBB build system
#       - it checks out my private copy of the bigbluebutton-build repository to call setup.sh for each of them
#    - the python3-vnc-collaborate package, built using python setuptools with the stdeb extension
#    - the bbb-vnc-collaborate package, which depends on python3-vnc-collaborate and calls it from systemd scripts
#    - something with pyjavaproperties
#    - a modified ssvnc package; the only change is to disable the escape sequence in the viewer
#    - vncdotool; build from github repository; I think it might be available on PyPi for pip install,
#      but I need a dpkg version to install it as an apt dependency
#    - tigervnc; I think we need 1.10.1 for something and bionic only comes with 1.7.0
#    - bbb-aws-hibernate; optional; only needed to hibernate an AWS system when the server is not in use; built with fpm
#    - bbb-auth-jwt; built with fpm; currently my standard way of authenticating into a collaborate server
#
# Finally, it uses reprepro to pull from the standard bigbluebutton repo, replaces the packages that need to
# be changed, package everything up with reprepro, and export my public key, combined with Fred's to bigbluebutton.asc.

# bash so we can use compgen
SHELL := /bin/bash

# Chicken-and-egg situation here
#
# We need to install these dependencies because stdeb's algorithm for
# converting python dependencies to dpkg dependencies only works if
# the package is already installed.
