Hi. I have both Python v2 and v3 installed on my system. The tests shown in the provided error log pass for me, in all cases: - no version - defaults to 3.9.8 make check TESTS='t/nobase-python.sh t/py-compile-basic.sh t/py-compile-basedir.sh t/py-compile-destdir.sh t/py-compile-option-terminate.sh t/python3.sh t/python10.sh t/python12.sh ' - explicit v2 (2.7.18): PYTHON=python2 make check TESTS='t/nobase-python.sh t/py-compile-basic.sh t/py-compile-basedir.sh t/py-compile-destdir.sh t/py-compile-option-terminate.sh t/python3.sh t/python10.sh t/python12.sh ' - explicit v3: PYTHON=python3 make check TESTS='t/nobase-python.sh t/py-compile-basic.sh t/py-compile-basedir.sh t/py-compile-destdir.sh t/py-compile-option-terminate.sh t/python3.sh t/python10.sh t/python12.sh ' I guess this got fixed in the repository since the defect was reported. Some of the tests touch the "uninstall" target and that certainly was changed. My Automake version: - branch: master - last commit ID: 0901ccdd0cb21bfa3911a2668615e388fef94426 - last commit date: Wed Mar 1 15:03:30 2023 -0800 Actually, I could fix t/python-prefix.sh to work with Python v2 and t/python-virtualenv.sh to work at all (didn't work by default for me). Patch attached. Now all tests with "py" in the name pass on my system (both with v2 and v3). I assume that Automake, 'make install' and 'make uninstall' do their job correctly (and that's most probably true) and it's just the tests that were doing wrong. -- Regards - Bogdan ('bogdro') D.
