Debian Patches

Status for libmaus2/2.0.813+ds-6

Patch Description Author Forwarded Bugs Origin Last update
add-support-for-loong64.patch workaround for architectures with broken sysconf.c
Some architectures in glibc do not define the sysconf.c file, and using the
generic posix sysconf.c file to call the _SC_LEVEL1_DCACHE_LINESIZE variable
returns 0 by default, which leads to failure of the test in
loongarch, ia64, s390x and other architectures,

This patch reference lscpu code to read the data in coherency_line_size file
directly can fix the above error, and it passes the test on x86 and loongarch.		 wuruilong <wuruilong@loongson.cn> yes debian
gcc-15.patch Fix build failure with gcc-15. This patch fixes the following type of build failures with gcc-15:

unlock-stdc++.patch unlock the standard C++ level. This patch drops passing the -std=c++17 option to the compiler. This
change is made necessary due to evolution in the atomics handling in
gcc-16 and increase strictness that translated into the build failure:

Newer standard C++ levels better handle this particular case
apparently.		 Étienne Mollier <emollier@debian.org> no debian 2026-08-05
