Thanks, I've merged it. I think it always built fine, but psi4 was broken at runtime so all the tests failed, but that did not lead to a build failure. With your patch, most of the tests pass and I'll have to investigate the remaining numerical issues. Michael

Bug#1027025: psi4: FTBFS with Python 3.11 as default version
Source: psi4 Version: 1:1.3.2+dfsg-3 Followup-For: Bug #1027025 X-Debbugs-Cc: j...@jp-hosting.net Based on some upstream discussion[1] of the same ImportError, it looks like this is related to the PYTHON_MODULE_EXTENSION suffix applied to the 'core' module at build-time by pybind11-related build infrastructure. During these build failures, the module is compiled with filename 'coreNone' instead of the expected filename 'core.', and that results in import-time errors. The cause relates to a Python distutils.sysconfig config var named "SO" (used to retrieve a compiled module's filename, including suffix), which was deprecated[2] in Python 3.4 in favour of a var named "EXT_SUFFIX" that provides similar information. The reason that psi4 v1.3.2 breaks in combination with Python 3.11 is that it uses a variant of pybind11's 'FindPythonLibsNew' helper module that predates the SO-to-EXT_SUFFIX transition (it references[3] only the former var) when determining the value for PYTHON_MODULE_EXTENSION. In Python 3.11, the SO var is no longer available. pybind11 handled this by providing a fallback[4] behaviour from v2.6.0, with some further adjustments[5] applied in v2.6.1. Upstream psi4 separately resolved the problem by commenting-out[6] a reference to PYTHON_MODULE_EXTENSION from psi4 version v1.4 and subsequent versions.

Bug#1027025: psi4: FTBFS with Python 3.11 as default version

Severity: serious

Hi Maintainer
Psi4 fails its build-time tests with Python 3.11 as the default
version, although the build doesn't fail outright, probably because of
the following in debian/rules:
override_dh_auto_test:
mkdir -p $(CURDIR)/builddir/tmp-scratch
-(cd builddir/tests; CTEST_OUTPUT_ON_FAILURE=TRUE ctest -L quicktests)
I've copied what I hope is the relevant part of the log below.
Regards
Graham
