Dear maintainer(s),

powerman fails to build from source with glibc 2.43, currently in
experimental. From the build log:

| make[3]: Entering directory '/build/reproducible-path/powerman-2.4.4/src/liblsd'

The full build log is available here [1].

The issue is due to ISO C23 declaration of bsearch, memchr, strchr,
strpbrk, strrchr, strstr, wcschr, wcspbrk, wcsrchr, wcsstr and wmemchr,
which now returns a pointer to a const-qualified type when the input
argument is a pointer to a const-qualified type [2].

I would like to thanks Emanuele Rocca for doing the archive rebuild on
a fast arm64 server.

Regards
Aurelien

Hi,

With the upload of glibc 2.43 to unstable, the packages now FTBFS in
unstable, hence upgrading the severity to serious.

Note that as a quick workaround, it is possible to roll back to C/C++17
standard using -std=c17, -std=gnu17, std=c++17 or std=gnu++17. This was
the default up to GCC 14, and GCC 15 changed it to C/C23.

Regards
Aurelien

Apparently, I made the last upload of powerman, so I'll pick this up.

J.

We believe that the bug you reported is fixed in the latest version of
powerman, which is due to be installed in the Debian FTP archive.

A summary of the changes between this version and the previous one is
attached.

Thank you for reporting the bug, which will now be closed.  If you
have further comments please address them to 1128740@bugs.debian.org,
and the maintainer will reopen the bug report if appropriate.
