Hi, Seems that python changes cause build fail https://swatbot.yoctoproject.org/collection/6991/ Regards, Oleksiy

I was curious to see how it looked but it isn't quite there yet :/ Cheers, Richard
Upstream Python is moving to pyproject.toml rather than setup.py and wheels rather than eggs. The main place this is documented is in PEP-517[1]. Installing packages with setup.py install is deprecated. We have a choice with the 'kirkstone' LTS release of introducing this series (and fixing any fall out during the stabilization period) or living with deprecated Python packaging for the duration of the LTS (at a minimum 2 years). This seems to be a compelling enough reason to bring in this series, even if it results in a slight slip of the 'feature freeze', which is officially tomorrow, Monday 21 Feb, 2022. This series bootstraps python3-setuptools-native, python3-flit-core-native, python3-wheel-native and python3-pip-native, simply unzipping the wheel into PYTHON_SITEPACKAGES_DIR. This allows all other recipes to be installed with pip, as intended by upstream. Three new classes are introduced: (1) flit_core which builds PEP-517 compliant packages which use flit_core.buildapi as their build-backend. (2) setuptools_build_meta which builds PEP-517 compliant packages which use setuptools_build_meta as their build-backend. (3) pip_install_wheel, which simply installs wheels built by other classes. The original setuptools3.bbclass do_compile is modified to 'setup.py bdist_wheel' (from python3-wheel-native) rather than the deprecated 'setup.py build' mechanism. The original setuptools3.bbclass do_install is modified to use the pip_install_wheel.bbclass to install wheels with pip rather than the deprecated 'setup.py install' mechanism. For pip install, we disable dependency checking (--no-deps) because it proves to be brittle in our environment without providing full wheel cache that seems like overhead that we do not need. We also disable fetching wheels from pypi (--no-index). This is no different than our normal workflow of requiring dependencies to be defined in a recipe. Missing from this series is documentation of the new features, classes and variables (this will be done under separate cover). Also desired and previously discussed in YP meetings is a helper function to warn that a recipe which currently inherits setuptools3 but has a pyproject.toml and defines a build-system.build-backend should instead use of the new PEP-517 classes. This function is still in progress. During testing, recipes which use python3-setuptools-scm are failing to determine the version of the python package, For several recipes, the fix was to use pyproject.toml and PEP-517 build backends. To be sure, other recipes are still going to fail for the short term, until the root cause can be determined. Another PEP-517 build-backend, poetry.core.masonry.api has been identified in recipes in meta-python, but not in oe-core. The python3-poetry-core recipe is WIP, but brings in a number of dependencies that are perhaps not worth it to bring into oe-core at this time. Rather we can support these recipes in meta-python?
