Python gets detected correctly but the Header File pyconfig.h can not be found - MSYS2 MinGW-w64 10.2.0

This might be related to boostorg/build#481 where the Python installation is built with PyMalloc, so the header path has an m suffix (e.g. path/to/Python/3.8.x/include/python3.8m)

Wow. I totally forgot about that Bug Report. Thanks for the Hint adeadman!

A general FYI for People interested: Since I have reported this Bug, I am building Boost on Linux and Windows always with:
--without-python
as a work-around.

This does not change the Detection of Python as it is hard-coded in the configuration Files but compilation works fine.

I am not using the Boost Libs currently, so I am not aware of the Cons of not building with / against Python support.

Have a nice Day.

I needed to build the Boost.Python libraries back in 2012 or so, and it was an absolute nightmare back then. Now, here in 2023, I'm having to do it again, and having the same b2 and jam headaches. Even ChatGPT can't get it to compile.... All we really need is better documentation. For example, I'm running into the age-old problem of the compiler complaining about not finding Python.h. Capital P in Python.h, at least on this Linux machine. I'm an extensive user of conda environments, and I'm trying to bootstrap and b2 off of one of my environments. I've burned through 3 full days now trying to get the config right, and there seems to be no hope. Of all the code I have written over the decades of writing code, nothing has ever been as completely frustrating as trying to build Boost.Python with bootstrap and b2. I'm hoping that by venting here, I go back to my build project and it magically compiles so I can get on with what I need to be doing.

For what it is worth, as is often the case, after ranting publicly, I quickly came up with a solution that had been confounding me for days. My notes, should anyone care are here: github.com/rlovell3/boost_python_compile_notes. Those notes are for building on Ubuntu and associated flavors, using a highly customized conda environment running Python 3.11. Thank you to all the Boost contributors. Boost is truly an amazing work. b2 is still a pain though, but I get it.
