Ada Community and GDB/Python problems

[Rick Newbie <nuttin@nuttn.nowhere>]

Hi all,

I'm trying to get going with Ada community edition. So far so good but I 
had major problems with Python. I always get error messages when trying 
to debug, messages that show that the wrong number of parameters are 
provided to Python calls. It is as if the community pack contains the 
wrong version of Python.
For instance I compiled my hello world program with debug info etc, then 
tried to start gdb from the commandline. At first it tells me it can't 
find the pyton libraries. Then I follow the suggestions and supply the 
python path like so:

gdb --data-directory=D:\GNAT\2019\share\gdb-8.3

and I get a ton of errors:

Again this is just the install package from Adacore. I am using Windows 
10 and I must admit that I don't have experience with gcc or gdb. To my 
knowledge there was never another python installation on my machine, not 
unless some other application installed it silently but I checked and 
can't find anything Python related, so this should be the only one 
(2.7.16). I just have no idea how to fix this since I would assume that 
the pack from Adacore should run out of the box.

Any help is appreciated.
