there are known issues with spdlog and libfmt-8
looks like one

[Comment 9 Georgy Yakovlev 2021-07-04 09:03:55 UTC]

added maintainers of spdlog and libfmt for possible input.
it does not fail for me with gcc10 though, maybe gcc11 is also a trigger.

upstream uses fmt 7.1.3

https://github.com/rizsotto/Bear/blob/master/third_party/fmt/CMakeLists.txt


so I limited dep for now

@toralf, could you be so kind to re-run the check at some point?

[Comment 12 Georgy Yakovlev 2021-07-04 09:31:44 UTC]

2021-07-01T17:42:28 >>> dev-libs/libfmt-8.0.0-r1
2021-07-01T17:42:49 >>> dev-libs/spdlog-1.8.5-r1
....
2021-07-03T06:50:38 >>> dev-libs/libfmt-8.0.1


so fmt was rebuilt


I tried to dig a little deeper and abidiff between 8.0.0 and 8.0.1 told me the following

43 Removed functions:
[D] 'function void fmt::v7::detail::assert_fail(const char*, int, const char*)'    {_ZN3fmt2v76detail11assert_failEPKciS3_}

43 Added functions:
[A] 'function void fmt::v8::detail::assert_fail(const char*, int, const char*)'    {_ZN3fmt2v86detail11assert_failEPKciS3_}


and here's the commit

https://github.com/fmtlib/fmt/commit/31a5f0d399edbb2000131c9253aa346afddc6387

they've changed namespace without bumping soname/subslot.

I took liberty to non-maintainer fix it, new subslot is 0/8.0.1 (0/${PV}) to stop the breakage.

I think it may be reasonable to use it for all ebuilds in the future.

Thanks for addressing this! You beat me to it :-)

I assumed you may be out because holidays, so rushed it to prevent delays and user frustration. no prob at all.
