Ronald Oussoren  added the comment:

I'd prefer a solution that uses symbols where the are available (weak linking). 

That way users on newer systems can use all functionality available there, 
without having multiple binaries.

I've done this in the past for older macOS versions, but don't know how 
involved such patches would be for current versions of CPython.

[Gregory Szorc]

Gregory Szorc  added the comment:

I ran into this with PyOxidizer. CPython's `configure` needs to be made aware 
of the current macOS SDK version and filter out symbols not present in the 
target macOS version. I worked around it by `undef`'ing some entries from the 
generated `pyconfig.h` file.

macOS's clang does emit some warnings when it sees symbols that shouldn't be 
used with the current target version. CPython's build system should consider 
adding -Werror=unguarded-availability-new to CFLAGS to turn these warnings into 
errors so they are caught at compile time and not run time. But there should be 
proper filtering of affected symbols first, otherwise people won't be able to 
build CPython when targeting older macOS versions.

This issue blocks QGIS distribution on MacOS for 10.11 and 10.12 releases, 
https://github.com/lutraconsulting/qgis-mac-packager/issues/22

I would like to know how much work is involved to fix the issue, possible 
whether there is a plan to fix it. Also we would appreciate quote & timeline 
for fix to i...@lutraconsulting.co.uk, so we can consider to sponsor this fix. 
Thanks

Joshua Root  added the comment:

This isn't just a cross-build issue, or rather (depending on how you look at 
it) cross-builds are increasingly the norm due to Apple only providing a newer 
SDK on older OS versions. For example the latest version of Xcode available for 
10.12 only comes with the 10.13 SDK.

This is true for other symbols as well, when deploying to older releases of 
macOS. 

I have added runtime checking for a number of symbols in the past, that could 
be extended to newer APIs.

On the road, hence brief.
