Error(s) that match a know pattern in addition to what has been reported in the summary:

Reported to upstream - https://github.com/open-telemetry/opentelemetry-cpp/issues/3239

I'll add 2 fixes (build fails for 2 different reasons both in clang and gcc-15).

does look like cdstdint include patch was accepted upstream but the fix is not yet in portage

attachment opentelemetry-cpp-1.16.1-cstdint.patch (will add) allows building with gcc-15.0.1_pre20250330

portage version is versions behind
   upstream has up to 1.20.0 
   portage latest has only 1.16.1

patch was not applied to 1.16.1 release upstream
