Description Bernd 2021-06-22 16:43:51 UTC 
This happens when rebuild against updated libfmt-8.0.0 with gcc-10. The error is

Reproducible: Always

Steps to Reproduce:
1. emerge =libfmt-8.0.0
2. emerge kodi
3.


Expected Results:  
Kodi is missing a proper SLOT operator on it dependency of libfmt, so the rebuild is not automatically triggered, but shown in the @preserved_rebuild set.

Comment 3 PhobosK 2021-06-22 17:08:19 UTC 
Same error goes for kodi-9999

This is because of the new dev-libs/libfmt-8.0.0-r1 that broke a lot of apps :(

Comment 6 Craig Andrews gentoo-dev 2021-06-23 14:48:53 UTC 
Can you please submit this as a PR to kodi at https://github.com/xbmc/xbmc ?

Also, does that patch also work when compiling against libmt 7?

Sorry for the delay, busy working days.
I tested only against libfmt 8. I will test against 7, it will take a while on Pi.

equery f libfmt | grep xchar

I presume it need something like
#if FMT_VERSION >= 80
#include <fmt/xchar.h>
