The current system python in the docker baseimage is py3.9, while the targetpython and hostpython built by p4a are py3.8, and this was causing linker issues in the pyqt5 build. It is also cleaner IMHO to have p4a handle what is needed for a recipe instead of assuming it is available in the system. (and I think this is how other existing recipes work) fixes https://github.com/spesmilo/electrum/issues/8016
Notes
The frozen dependency lists in this folder are generated files.
- Starting from
contrib/requirements/requirements*.txt, - we use the
contrib/freeze_packages.shscript, - to generate
contrib/deterministic-build/requirements*.txt.
The source files list direct dependencies with loose version requirements, while the output files list all transitive dependencies with exact version+hash pins.
The build scripts only use these hash pinned requirement files.
