[LAD] installing python extensions

Hello all, I have some mixed python/C++ packages, e.g. zita-audiotools and zita-jacktools. To install these I expect the following to happen: 1. The C++ parts are compiled and combined into a *.so file which is a python extension. 2. The *.so and the python parts, any data etc. get installed into the user's /usr/lib/python*.*/site-packages. To make this as easy as possible I provide a setup.py and a Makefile, so that all that should be required is: make; sudo make install Originally this used distutils, when that got 'deprecated' this changed to setuptools. So until recently the Makefile was something like: ---- PY = /usr/bin/python3 build: $(PY) ./setup.py build install: $(PY) ./setup.py install clean: $(PY) ./setup.py clean rm -rf build dist zita_jacktools.egg-info --- Then I got warnings telling me that calling setup.py directly is now also deprecated, and that I should use 'official tools' to build and install. What exactly that means I was unable to find out, but the following seems to work: ---- PY = /usr/bin/python3 build: $(PY) -m build -w install: pip install --force-reinstall dist/*.whl clean: rm -rf build dist *.egg-info *~ ---- But this still produces a warning: Now clearly installing things in site-packages requires root, so what is then the recommended method ?? And why the virtual environment (which is used by build anyway) ?? If anyone can shed some light on this mess he/she will deserve my eternal gratitude. Ciao, -- FA
