From f729cfc33f258781c5fd85a3d8773bf6149d12db Mon Sep 17 00:00:00 2001 From: Bennett Goble Date: Sat, 5 Jun 2021 22:02:54 -0700 Subject: SL-15742: Convert build scripts to Python 3 This changeset makes it possible to build the Second Life viewer using Python 3. It is designed to be used with an equivalent Autobuild branch so that a developer can compile without needing Python 2 on their machine. Breaking change: Python 2 support ending Rather than supporting two versions of Python, including one that was discontinued at the beginning of the year, this branch focuses on pouring future effort into Python 3 only. As a result, scripts do not need to be backwards compatible. This means that build environments, be they on personal computers and on build agents, need to have a compatible interpreter.
