ok, now with 8.0.b8, you can just do
"export SAGE_PYTHON3=yes"
and then "make build". This should succeed, with no error message.
Then try "./sage"
This fails with some traceback about not finding sage.repl.interpreter.
Once again, can *please* someone help to fix that ?
OK, in the last few days I finally executed a plan for sage-on-gentoo
to be able to build and sage for python2.7 and python3.6 at the same time.
The main obstacle to do that are pynac and brial. pynac being the
hardest problem. I have been creative in a way that they cannot
currently be ported back to sage proper. And of course it needs a PR
I already mentioned here to build at all with python3.
In any case I have a build, with documentation courtesy of the python2.7
part.
My build is dangerously based on volker's develop branch where he
merges tickets and tests them before releasing. So I have a number
of py3 tickets included beyond 8.0.beta8 but I don't include any other
tickets.
I hear how unicode will be a problem. Well when I try sage with python3
I crash like everyone else and my trace back ends up with
