From d184dbbba8987d9f387feb25791ed891e108dabc Mon Sep 17 00:00:00 2001 From: Tobias Mueller Date: Tue, 20 Dec 2016 18:00:36 +0100 Subject: [PATCH] python: Conditionally provide py3 argument to SWIG * lang/python/setup.py.in: Only call with -py3 when we run under python3 or higher. -- If we ever remove the -builtin flag and leave the the -py3 flag, SWIG will generate Python code which will be incompatible with Python 2, because the py3 flag generates python3 code which is incompatible with python2. So we conditionally generate SWIG bindings with -py3.
