    | ../../elfutils-0.191/src/srcfiles.cxx:81:18: error: unused variable 'BUFFER_SIZE' [-Werror,-Wunused-const-variable]
    |    81 | constexpr size_t BUFFER_SIZE = 8192;

@quaresmajose there is a fix staged in core layer master-next already for this. Please cherry-pick that in meantime.

https://lore.kernel.org/openembedded-core/20240309235748.517154-1-raj.khem@gmail.com/

secondly, move your meta-clang to latest tip of master branch. You also need.

My error is not the same as this one unused-private-field vs unused-const-variable

I am already using the latest tip, for now I have fixed it in my layer but I will also submit a patch for elfutils-devel to remove the unused BUFFER_SIZE.
