Commencez par l’échec signalé dans rules_python/python/private/toolchains_repo.bzl, au niveau de _resolved_interpreter_os_alias_impl, et suivez l’appel à python_register_toolchains depuis le WORKSPACE. Reproduisez le build Bazel ou le build du wheel sur FreeBSD 14.2 amd64. Le travail est terminé lorsque l’hôte FreeBSD est pris en charge sans l’erreur de plateforme signalée.
