Bernd, All,
On 2021-01-03 16:03 +0100, Bernd Kuhls spake thusly:
> Kodi is in transition to support python3 instead of python2:
> https://kodi.wiki/view/General_information_about_migration_to_Python_3
>
> "For Kodi 18 (Leia), only addons that are compatible with both Python 2
> and 3 will be accepted to the official addon repository."
>
> Some of these addons depend on the Kodi addon script.module.future to
> provide support for both python versions.
>
> The script.module.future addon contains python-future:
> https://kodi.wiki/view/General_information_about_migration_to_Python_3#Future
> which in turn needs lib2to3 to be included in the target build of
> python3: http://python-future.org/automatic_conversion.html
>
> Kodi addons depending on the script.module.future addon are crashing on
> buildroot due to lib2to3 missing in the build.
>
> LibreELEC added lib2to3 to python3 to fix the problem:
> https://forum.libreelec.tv/thread/21239-lib2to3-pgen2-parse-missing/
> https://github.com/LibreELEC/LibreELEC.tv/pull/4146
>
> This patch provides the Config.in option to be used by Kodi 19.

Applied to master, thanks.
However, I had to do a few fixes;
- fix conflicts due to local changes in author's tree
- fix typ in variabl name (PYTHON_CONF_OPTS -> PYTHON3_CONF_OPTS)
Please be carefull when you send patches: rebase them on master before
sending (see below).
Also, run: make check-package, that will hint at the variable typo I had
to fix too.

We do not have that in master, so the patch did not apply cleanly...
Will you send support for the bdb module?
