Source: netty
Version: 4.1.33-1
Severity: important
Tags: ftbfs
Justification: fails to build from source
Hey,
It seems that netty fails to build on 32 bit architectures, we hit that in our
rebuild on 32 bit as does the reproducible builder see e.g:
https://tests.reproducible-builds.org/debian/rb-pkg/buster/armhf/netty.html
Tbh i was a bit surprised netty does some native building given it only ships
an architecture all package. In any case the issue seems to mostly be due to
building with -Werror which makes things fail on warnings. I've attached the
debdiff we used as workaround for this
