Dear maintainer(s), fyi fails to build from source with glibc 2.43, currently in experimental. From the build log: | dh_auto_build | cd obj-aarch64-linux-gnu && LC_ALL=C.UTF-8 ninja -j128 -v | [1/4] /usr/bin/env LC_ALL=C ../generate-version.sh 1.0.4 ../ version.h | [2/4] /usr/bin/meson --internal exe --capture doc/fyi.1 --feed ../doc/fyi.1.scd -- /usr/bin/scdoc | [3/4] cc -Ifyi.p -I. -I.. -I/usr/include/dbus-1.0 -I/usr/lib/aarch64-linux-gnu/dbus-1.0/include -fdiagnostics-color=always -DNDEBUG -D_FILE_OFFSET_BITS=64 -Wall -Winvalid-pch -Werror -std=c11 -fno-asynchronous-unwind-tables -g -O2 -Werror=implicit-function-declaration -ffile-prefix-map=/build/reproducible-path/fyi-1.0.4=. -fstack-protector-strong -fstack-clash-protection -Wformat -Werror=format-security -mbranch-protection=standard -Wdate-time -D_FORTIFY_SOURCE=2 -MD -MQ fyi.p/main.c.o -MF fyi.p/main.c.o.d -o fyi.p/main.c.o -c ../main.c | FAILED: [code=1] fyi.p/main.c.o | cc -Ifyi.p -I. -I.. -I/usr/include/dbus-1.0 -I/usr/lib/aarch64-linux-gnu/dbus-1.0/include -fdiagnostics-color=always -DNDEBUG -D_FILE_OFFSET_BITS=64 -Wall -Winvalid-pch -Werror -std=c11 -fno-asynchronous-unwind-tables -g -O2 -Werror=implicit-function-declaration -ffile-prefix-map=/build/reproducible-path/fyi-1.0.4=. -fstack-protector-strong -fstack-clash-protection -Wformat -Werror=format-security -mbranch-protection=standard -Wdate-time -D_FORTIFY_SOURCE=2 -MD -MQ fyi.p/main.c.o -MF fyi.p/main.c.o.d -o fyi.p/main.c.o -c ../main.c | ../main.c: In function ‘main’: | ../main.c:558:27: error: initialization discards ‘const’ qualifier from pointer target type [-Werror=discarded-qualifiers] | 558 | char *split = strchr(type_str, ':'); | | ^~~~~~ | ../main.c:563:23: error: assignment discards ‘const’ qualifier from pointer target type [-Werror=discarded-qualifiers] | 563 | split = strchr(name, ':'); | | ^ | cc1: all warnings being treated as errors | ninja: build stopped: subcommand failed. | dh_auto_build: error: cd obj-aarch64-linux-gnu && LC_ALL=C.UTF-8 ninja -j128 -v returned exit code 1 | make: *** [debian/rules:7: binary] Error 25 | dpkg-buildpackage: error: debian/rules binary subprocess failed with exit status 2 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.
