As with earlier versions, with OS X 26.2 I'm seeing:

File "src/sage/misc/sagedoc.py", line 709, in sage.misc.sagedoc.format
Failed example:
    cython('\n'.join(cython_code))                                            # needs sage.misc.cython
Expected nothing
Got:
    ld: warning: building for macOS-15.0, but linking with dylib '/Users/palmieri/Sage/TESTING/sage-10.9.beta1/local/lib/libec.14.dylib' which was built for newer version 26.0
    ld: warning: building for macOS-15.0, but linking with dylib '/Users/palmieri/Sage/TESTING/sage-10.9.beta1/local/lib/libgsl.27.dylib' which was built for newer version 26.0

We should be able to filter out warning messages like these in src/doctest/parsing.py, but maybe we can set flags to specify which version of Mac OS we're building for. Is MACOSX_DEPLOYMENT_TARGET being incorrectly set somewhere?

Sage does not set it. (have a look at the output of "git grep
MACOSX_DEPLOYMENT_TARGET").
Upstream dependencies might set it, though. (however, eclib does not
do it, as far as I know)

Perhaps you have it set, or your toolchain?
What's the Cython version, i.e. the output of

import cython
cython.__version__

I don't have it set myself. When I upgraded the OS version, I also upgraded the command-line tools to the corresponding version, so I hope that is not causing this.

 

What's the Cython version, i.e. the output of

import cython
cython.__version__

Sage builds its own Cython, so this prints '3.1.3'.

With cython 3.2.4, I don't see this warning on macOS.
See https://github.com/sagemath/sage/pull/41409

With cython 3.2.4, I still see this warning on OS X 26.2
