While QEMU will initially aim to support the + distribution's default runtime, it may later increase its minimum version + to any newer python that is available as an option from the vendor. + In this case, it will be necessary to use the ``--python`` command line + option of the ``configure`` script to point QEMU to a supported + version of the Python runtime. + + As of QEMU |version|, the minimum supported version of Python is 3.6. + +Python build dependencies + Some of QEMU's build dependencies are written in Python. Usually these + are only packaged by distributions for the default Python runtime. + If QEMU bumps its minimum Python version and a non-default runtime is + required, it may be necessary to fetch python modules from the Python + Package Index (PyPI) via ``pip``, in order to build QEMU. + +Optional build dependencies + Build components whose absence does not affect the ability to build + QEMU may not be available in distros, or may be too old for QEMU's + requirements. Many of these, such as the Avocado testing framework + or various linters, are written in Python and therefore can also + be installed using ``pip``. Cross compilers are another example + of optional build-time dependency; in this case it is possible to + download them from repositories such as EPEL, to use container-based + cross compilation using ``docker`` or ``podman``, or to use pre-built + binaries distributed with QEMU. + + Windows ------- |
