[C++-sig] Python support in boost::python (what version)

[Jones, Torrin A (US)]

Anything above version 2.2
OK, I understand what you are saying below, but there seems to be a little bit more to this . . .

Example: This was fixed in boost-1.67.0.  So in theory, nothing below boost python 1.67.0 supports Python 3.7.  I guess I didn't ask about older versions of boost python though.

https://github.com/boostorg/python/commit/660487c43fde76f3e64f1cb2e644500da92fe582

For clarity, my boss is asking, "what version of python does boost python support?"  I was hoping there was some kind of table or something, but I guess the answer is something like, "It supports whatever version of python was out at the time that boost python was released?"  And then we can go back and look at release dates.  LOL.

Ex: boost python 1.66.0 was released/tagged on Nov 17, 2017.  Python 3.6.3 was released on Oct 3, 2017.  Python 3.6.4 was released on Dec 19. 2017.  So in theory boost python 1.66.0 has support for Python 3.6.3, but does not have support for Python 3.6.4.  I know that's ludicrous but, I work in the corporate world so here we are.

There isn't another question here, but if you have any other thoughts on this please reply.

I noticed in the python build file (see link below), it will only find from version 1.5 to 3.4.  Does this mean that boost python really only supports up to 3.4?  Folks do appear to be using other versions, but the fact that this only goes to 3.4 leads me to believe that is as far as it's been tested.  Is that right?

Definitely not. You are right, though: this file needs to be fixed. (I'm not maintaining this file myself, so I'll follow up with the relevant people (Boost.Build).)

Boost internally regularly builds and tests Boost.Python with versions > 3.4. and I know various distributions containing Boost.Python packages built against more recent Python versions.

See for example https://anaconda.org/anaconda/boost/files
What are the official versions?  Is there any documentation that says that?

Not really, as Boost only "officially" releases source packages. Users are free to compile against a large range of tools and prerequisites (compilers, Python versions, etc.).

If you find any issues building and running against a particular Python version, please file a bug report, and I'll try to help as quickly as possible.
