Source: rkcommon
Version: 1.14.2-1
Severity: important
Tags: ftbfs forky sid
Justification: fails to build from source
User: [email protected]
Usertags: glibc-2.42

Dear maintainer,

During a rebuild of all packages in unstable with glibc 2.42 from
experimental, your package failed to build. Below you will find how the
build ends. If required, the full build log is available here:

https://people.debian.org/~aurel32/glibc-2.42/

The build failure is due to the addition of the rsqrt function (part of
ISO C12) to glibc 2.42, now conflicting with the rkcommon source:

https://sourceware.org/git/?p=glibc.git;a=blob;f=NEWS;h=f0b0e924a45c7698e6ca6415f2d9a096a24e37df;hb=d2097651cc57834dbfcaa102ddfacae0d86cfb66#l12

About the archive rebuild: The build was made on virtual machines from
AWS, using sbuild, a reduced chroot with only build-essential packages
and glibc 2.42 from experimental.

Regards
Aurelien
