If so, can you add a Fixes: tag? Also, can you investigate since when this problem exists, so that our LTS maintainers can understand whether they need to backport this fix or not? > Upstream abseil has no support for the n32 ABI, so disable the package > for that ABI. The o32 and n64 ABIs are unaffected. But then doesn't package/abseil-cpp/Config.in also need to be modified? And is it possible for python-grpcio to use the Buildroot-provided abseil, instead of using its bundled version? Thanks a lot!
