#63458 new defect

python37 @3.7.12_0 can't build py37-setuptools on 10.4 or 10.5

Component: ports Version:

Port: python37

Description

The summary isn't quite correct in that 10.5 i386 works, but 10.4-10.5 ppc, 10.4 i386, and 10.5 x86_64 all fail. 10.4 x86_64 is untested. 10.6-10.15 all work.

Rolling back py-setuptools to 57.1 doesn't help, so the problem seems to be in python37 @3.7.12_0. The logs aren't terribly helpful, in that the only indication of trouble is a nonzero exit status from running setup.py in the py37-setuptools build procedure.

There's no similar issue with other Python versions.

the python c interface library was failing to build on < 10.6 on newer pythons, 38, 39, and we fixed that last year with this:

[7da358db764df2913c58385f3857e248191cc460/macports-ports]

at the time, python37 was working and didn't have that issue. However, there have been several updates to python37 since then, so perhaps some of python38+ has been backported into python37 and might need a similar patch.

That might be a place to start peeking.

Very little changed in this python version (note that we don't even use the bundled copy of expat): https://github.com/python/cpython/compare/v3.7.11..v3.7.12

Could be something to do with the new libffi version?

When running the failing command manually, I receive the error:

That's because you don't have PYTHONPATH pointing to the bootstrap modules like the port does.
