#14694 — change in the extention importation with 3.11

Hello, I am trying to fix this bug

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1024859

I find the error message not very informative...

:~/$ python3.11
Python 3.11.0+ (main, Nov  4 2022, 09:23:33) [GCC 12.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import scitbx_linalg_ext
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
SystemError: initialization of scitbx_linalg_ext raised unreported
exception
>>> 

I would like your opinion and some help in order to fix this or at least 
understand what is going on.

ther extension was build with boost_python, maybe something is wrong 
also with boost_python and Python3.11.

I do not know if other packages using boost_python are affected like 
this.

thanks for considering

Frederic

I briefly looked at #1023909 (python-pgmagick FTBFS with Python 3.11 as 
supported version) and found the same error. I spent some time trying to 
step through loading the extension with gdb and found that the failure 
is somewhere in amongst some boost macros associated with initialising 
the extension. I didn't actually manage to isolate the issue, however.

Is there a wider problem with boost python that needs addressing perhaps?

regards
Stuart

#14696

My pytango package has the same probleme...

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1024078

I: pybuild base:240: cd /<<PKGBUILDDIR>>/.pybuild/cpython3_3.11_tango/build; python3.11 -m pytest tests
ImportError while loading conftest '/<<PKGBUILDDIR>>/.pybuild/cpython3_3.11_tango/build/tests/conftest.py'.
tests/conftest.py:3: in <module>

tango/__init__.py:83: in <module>
    from ._tango import (
E   SystemError: initialization of _tango raised unreported exception


It use also the boost_python library... something is smelly around boost_python and python3.11...

Cheers.
