Research direction

Start with bootstrap.sh and the b2 Python configuration path, then reproduce the reported commands using the official Python 3.10 macOS installer. Compare the executable names each step checks, especially python versus python3. Done means Boost.Python 3 configures and builds successfully on this installation.

Written by the indexing model from the issue text.

Description

Might be related to https://github.com/boostorg/boost/issues/503 but building Boost Python 3 (Boost 1.80.0) with

./bootstrap.sh --with-libraries=python --with-python=python3
./b2 --debug-configuration --debug-building --debug-generator install

does not work: bootstrap.sh seems to work as it detected the right Python root location (I am using official Python installer at python.org instead of MacPort in the aforementioned issue)

Detecting Python version... 3.10
Detecting Python root... /Library/Frameworks/Python.framework/Versions/3.10

However, b2 reports

notice: [python-cfg] Configuring python...
notice: [python-cfg]   user-specified version: "3.10"
notice: [python-cfg]   user-specified cmd-or-prefix: "/Library/Frameworks/Python.framework/Versions/3.10"
notice: [python-cfg] Checking interpreter command "/Library/Frameworks/Python.framework/Versions/3.10/bin/python"...
notice: [python-cfg] running command '/Library/Frameworks/Python.framework/Versions/3.10/bin/python -c "from sys import *; print('version=%d.%d\nplatform=%s\nprefix=%s\nexec_prefix=%s\nexecutable=%s' % (version_info[0],version_info[1],platform,prefix,exec_prefix,executable))" 2>&1'
notice: [python-cfg] ...does not invoke a working interpreter

and apparently, the Python 3 installer on macOS does not created bin/python, only bin/python3. Shouldn't it take into account the suggested name for the Python executable in bootstrap? (It builds perfectly for Python 2.7 included in macOS.)
