For this compilation Problem there exists a current Upstream Bug:
Comment 4 Max Steel 2023-08-30 08:57:26 UTC
The mentioned patch fixes the C++14 Errors, but another error for undefined symbols in abseil-cpp is also mentioned and not yet fixed.

Regardless i attach the patch here, for your convenience.

clementine fix for protobuf

Not yet fully working fix for C++14 Compatibility

On current abseil-cpp Version the referenced Symbol does indeed not exist. But there exists an similar Symbol with a slightly different version.

Comment 6 Max Steel 2023-08-30 10:55:59 UTC
Downgrading abseil-cpp to 20230125.3-r1 and protobuf to 21.12 does work

Steps to reproduce
1. # cat >> /etc/portage/package.accept_keywords/zzzz << EOF
>=dev-libs/protobuf-23.3 -~amd64
>=dev-cpp/abseil-cpp-20230802 -~amd64
2. # emerge -uDN @world
3. # emerge @preserved-rebuilds
Comment 7 Alexey 2023-09-28 07:24:09 UTC
Adding "absl_log_internal_check_op absl_log_internal_message" to `target_link_libraries(libclementine-tagreader` fixes the build, however, it indicates that either protobuf or abseil-cpp forgot to declare some dependency in their exported cmake configs

This is solved with the commit referenced above. Should it be closed?
Comment 10 Alexey 2023-10-24 19:06:06 UTC
I sometimes randomly delay closing until the fixed package is stabilized and the bad version is removed, but yeah, can close it already...
Comment 11 Fat-Zer 2023-12-08 03:04:22 UTC
Note that the clementine-1.4.0_rc2-absl.patch causes a build failure when linking against older dev-cpp/abseil-cpp: see bug 919422.
