Installing Python 3.8.3 with tkinter

[Klaus Jantzen]

Hi,

Trying to install Python 3.8.3 with tkinter I run configure with the 
following options

./configure --enable-optimizations --with-ssl-default-suites=openssl 
--with-openssl=/usr/local --enable-loadable-sqlite-extensions 
--with-pydebug --with-tcltk-libs='-L/opt/ActiveTcl-8.6/lib/tcl8.6' 
--with-tcltk-includes='-I/opt/ActiveTcl-8.6/include'

Running Python gives the following information

Python 3.8.3 (default, Jul 22 2020, 11:52:15)
[GCC 8.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
 >>> import sqlite3
 >>> import tkinter
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
   File "/usr/local/lib/python3.8/tkinter/__init__.py", line 36, in <module>
     import _tkinter # If this fails your Python may not be configured 
for Tk
ModuleNotFoundError: No module named '_tkinter'
 >>>

Obviously there is something wrong with my configure options.

How do that correctly?

Thanks for any help.
