This patchset allows turning on Python freethreading by using
a new DISTRO_FEATURES setting:
DISTRO_FEATURES += "python_freethreading"
and optionally:
DISTRO_FEATURES_NATIVE += "python_freethreading"
The change to python3-dir.bbclass is crucial, as all python module
build helper classes rely on it.
I also added native variants of some settings because another
series against meta-openembedded is needed to complete this one.
In that, the change to the fontforge recipe relies on the native
setting for setting BUILD_LDFLAGS.
Looking at those other patches in the series, they don't seem to
be conditional on the distro feature.
Are those changes valid for a build with and without freethreading ?
Yes!
The main change is in python3-dir.bbclass, and the recipe tweaks
are just adaptations to the fact that only ${PYTHON_DIR} is needed,
not ${PYTHON_DIR}${PYTHON_ABI} from that point.
I was thinking that the introductory mail stressed this enough.
FWIW, less than 30 recipes was spelling the latter out in
openembedded-core and meta-openembedded combined.
That's the type of information, along with the benefits of enabling
this would be information expected in a 0/N introductory patch.
Cheers,

All of the changes included here were successfully build tested,
except for the gdb-cross-canadian change. That one failed, but
it's included for completeness.
Quite a few of python modules were build tested for native and
target builds, including python3-pytorch from my meta-python-ai
with reduced RDEPENDS because e.g. python3-onnx there failed
to build with freethreading enabled.
All in all, this series at least allows to get things going.
Though maybe not for Yocto 6.0, as it's quite late.
Best regards,
