libpst fails to build with Python 3.10.0a2.

  results of the Python check:
    Binary:      no
    Library:     no
    Include Dir: no
configure: error: python binary not found

Seems like there is missing check for python3.10.

For the build logs, see:
https://copr-be.cloud.fedoraproject.org/results/@python/python3.10/fedora-rawhide-x86_64/01757128-libpst/

For all our attempts to build libpst with Python 3.10, see:
https://copr.fedorainfracloud.org/coprs/g/python/python3.10/package/libpst/

Testing and mass rebuild of packages is happening in copr. You can follow these instructions to test locally in mock if your package builds with Python 3.10:
https://copr.fedorainfracloud.org/coprs/g/python/python3.10/

Let us know here if you have any questions.

Python 3.10 will be included in Fedora 35. To make that update smoother, we're building Fedora packages with early pre-releases of Python 3.10.
A build failure prevents us from testing all dependent packages (transitive [Build]Requires), so if this package is required a lot, it's important for us to get it fixed soon.
We'd appreciate help from the people who know this package best, but if you don't want to work on this now, let us know so we can try to work around it on our side.

Comment 1 Miro Hrončok 2020-11-12 10:05:16 UTC
The configure script has:

		if test -z "$ac_python_version"; then
			if test -n "$PYTHON_VERSION"; then
				ac_python_version=$PYTHON_VERSION
			else
				ac_python_version=`$PYTHON -c "import sys; \
					print (sys.version[:3])"`
			fi
		fi

That's why it doesn't work IMHO:

$ python3.10
>>> import sys
>>> print (sys.version[:3])
3.1
