  The nightly builds are those on 
https://code.gnucash.org/builds/win32/stable/, right?
Would it be possible to additonally provide a version there which 
includes the Python bindings? No, there's no way to make that work with 
an installed package.

  That depends on what you want to use for your Python. If you can use 
the MSYS2 environment from Powershell (some MSYS2 things work directly 
in Powershell, others need a Bash shell) then you can simply add 
-DWITH_PYTHON=ON to the CMakeArgs in jhbuild and build it. Don't run the 
installer, just add 
c:\gcdev64\gnucash\stable\inst\lib\python3.11\site-packages to 
PYTHONPATH and run your scripts.

After starting from scratch I'm now able to run a successful build 
including the Python bindings.

After adding
C:\Users\mu\Entwicklung\GnuCash\gcdev64\gnucash\stable\inst\lib\python3.11\site-packages
to PYTHONPATH my script now starts and does no longer complain about the 
gnucash imports.

But the script aborts and it looks like Python does not find 
_gnucash_core_c.dll in this folder. :-(

I also added 
C:\Users\mu\Entwicklung\GnuCash\gcdev64\gnucash\stable\inst\lib\python3.11\site-packages\gnucash 
to the Windows Path, but this does not help.

Do you also have 
C:\Users\mu\Entwicklung\GnuCash\gcdev64\gnucash\stable\inst\lib and 
C:\Users\mu\Entwicklung\GnuCash\gcdev64\gnucash\stable\inst\lib\gnucash 
in %PATH% ?

I've added them now, but it makes no difference.

Yes, they are there the following files:

__init__.py
_gnucash_core_c.dll
_sw_app_utils.dll
_sw_core_utils.dll
app_utils.py
deprecation.py
function_class.py
gnucash_business.py
gnucash_core.py
gnucash_core_c.py

folder __pycache__

Some of these files are mentioned in the error messages above.

Could it be a problem for  importlib.import_module() that GnuCash is 
build with Python 3.11 32-bit and I have Python 3.11 64-bit installed?

Regards,.
