Get Python3 to build its ssl and tkinter modules on macOS

[Samuel Lelievre]

Dear sage-devel,

on macOS, is there a recommendation on how to

get Python3 to build its ssl and tkinter modules

when building Sage from source?

I'm using macOS 10.14.6 Mojave.

Regarding ssl, if I run `make openssl` before

running `make`, then Python3 gets built with

its ssl module. I just have to remember to do that,

otherwise I then have to run `make openssl`

followed by `sage -f python3`.

Regarding tkinter, I have run `brew install tcl-tk`

to install Tcl/Tk using Homebrew, but it does not

seem to help. I also tried installing Tcl and Tk

from source, but it still does not seem to get

picked up at the time of building Python3.

Kind regards,

Samuel Lelièvre

This is not quite answering your question, but Marc Culler built a version of Tk 8.6.10 (all but very recent versions have issues on 10.14 and 10.15) and posted it here 

https://bitbucket.org/t3m/snappy/downloads

together with a small package "mac_sage9.tgz" which installs a version of "tkinter" and "openssl".  It targets the binary release, but should work if you build from source.

Best,

Nathan

The latest beta allows you to use Python3 from (say) Homebrew.
By looking at https://github.com/Homebrew/homebrew-core/blob/master/Formula/python.rb
I gather it comes with ssl.

You can modify Homebrew's formula to include tcl-tk in its deps, too, cf e.g.
https://gist.github.com/iexa/2ac761bfd96ab78988b76c030d54a5b8
(although the latter needs a modification if you need Python 3.7, not
Python 3.8 (and Sage needs 3.7))
- go over revisions of this gist to get 3.7, I guess
