Re: [Jython-dev] Building Jython3

[Jim B. <jim...@py...>]

Good tip. This works for me on OSX:

$ PYTHONIOENCODING=ascii dist/bin/jython -S
Jython 3.5.1a1+ (, Jun 3 2017, 21:59:14)
[Java HotSpot(TM) 64-Bit Server VM (Oracle Corporation)] on java1.8.0_112
>>> print(42)
42
>>>

We have some work in front of us to really get past this point.
