Hi Frédéric, thanks for the hard work on making Sage Python3-compatible! I succeeded in building Sage 8.3.beta1 both for Python2 and for Python3. I started using "SagePy3" for regular work, switching to "SagePy2" only when "SagePy3" won't do the work. I thus noted there's a fair amount one can already do with "SagePy3". > Our next goal is to get the documentation build.

I care a lot! But all I can do so far (not that it helps a lot) is build each new beta both for Py3 and Py2 and work primarily with the Py3 one, switching to the Py2 one only as needed. By the way, did "SagePy3" 8.3.beta2 build for anyone? I had no luck getting it to build under (now unsupported) macOS 10.10.5. I have to try 8.3.beta3 now that it is out. Do we ensure each new beta builds for Py3 on supported platforms? Maybe the announcement for each new beta on sage-release could remind readers that https://trac.sagemath.org/ticket/15530 has the instructions for building a Python3-based Sage? -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
