I tested manually building test_cext with Py_TARGET_ABI3T and rename the extension to test_cext.abi3t.so: ./python -m venv env env/bin/python -m pip install setuptools cd Lib/test/test_cext/ CPYTHON_TEST_EXT_NAME=test_cext CPYTHON_TEST_ABI3T=1 ../../../env/bin/python setup.py build_ext cd build/lib.linux-x86_64-cpython-315-pydebug/ mv test_cext.cpython-315d-x86_64-linux-gnu.so test_cext.abi3t.so cd ../../../../.. PYTHONPATH=Lib/test/test_cext/build/lib.linux-x86_64-cpython-315-pydebug/ ./python -c 'import test_cext; print(test_cext.__file__)' Output: Lib/test/test_cext/build/lib.linux-x86_64-cpython-315-pydebug/test_cext.abi3t.so It works as expected (I can import the C extension named .abi3t.so). Note: I used a debug build of Python which is not good to use the stable ABI, but it was for a quick test :-) |
