[This bug is NOT targeted to the upcoming trixie release] Please keep this issue open in the bug tracker for the package it was filed for. If a fix in another package is required, please file a bug for the other package (or clone), and add a block in this package. Please keep the issue open until the package can be built in a follow-up test rebuild. The package fails to build in a test rebuild on at least amd64 with gcc-15/g++-15, but succeeds to build with gcc-14/g++-14. The severity of this report will be raised before the forky release. The full build log can be found at: http://qa-logs.debian.net/2025/02/16/amd64exp/jove_4.17.5.3-1_unstable_gccexp.log.gz The last lines of the build log are at the end of this report. To build with GCC 15, either set CC=gcc-15 CXX=g++-15 explicitly, or install the gcc, g++, gfortran, ... packages from experimental. apt-get -t=experimental install g++ GCC 15 now defaults to the C23/C++23 standards, exposing many FTBFS. Other Common build failures are new warnings resulting in build failures with -Werror turned on, or new/dropped symbols in Debian symbols files. For other C/C++ related build failures see the porting guide at http://gcc.gnu.org/gcc-15/porting_to.html [...] 465 | bufname(b) | ^~~~~~~ buf.c: In function ‘buf_clear’: buf.c:486:1: warning: old-style function definition [-Wold-style-definition] 486 | buf_clear(b) | ^~~~~~~~~ buf.c: In function ‘buf_exists’: buf.c:516:1: warning: old-style function definition [-Wold-style-definition] 516 | buf_exists(name) | ^~~~~~~~~~ commands.c: In function ‘FindCmd’: commands.c:120:1: warning: old-style function definition [-Wold-style-definition] 120 | FindCmd(proc) | ^~~~~~~ buf.c: In function ‘do_stat’: commands.c: In function ‘ExecCmd’: commands.c:132:1: warning: old-style function definition [-Wold-style-definition] 132 | ExecCmd(cp) | ^~~~~~~ buf.c:551:1: warning: old-style function definition [-Wold-style-definition] 551 | do_stat(name, target, flags) | ^~~~~~~ buf.c: In function ‘setbname’: buf.c:651:1: warning: old-style function definition [-Wold-style-definition] 651 | setbname(b, name) | ^~~~~~~~ buf.c: In function ‘setfname’: buf.c:670:1: warning: old-style function definition [-Wold-style-definition] 670 | setfname(b, name) | ^~~~~~~~ buf.c: In function ‘do_find’: buf.c:709:1: warning: old-style function definition [-Wold-style-definition] 709 | do_find(w, fname, force, do_macros) | ^~~~~~~ buf.c: In function ‘SetABuf’: buf.c:770:1: warning: old-style function definition [-Wold-style-definition] 770 | SetABuf(b) | ^~~~~~~ buf.c: In function ‘valid_bp’: buf.c:780:1: warning: old-style function definition [-Wold-style-definition] 780 | valid_bp(bp) | ^~~~~~~~ buf.c: In function ‘SetBuf’: buf.c:792:1: warning: old-style function definition [-Wold-style-definition] 792 | SetBuf(newbuf) | ^~~~~~ buf.c: In function ‘do_select’: buf.c:814:1: warning: old-style function definition [-Wold-style-definition] 814 | do_select(w, name) | ^~~~~~~~~ buf.c: In function ‘lastline’: buf.c:837:1: warning: old-style function definition [-Wold-style-definition] 837 | lastline(lp) | ^~~~~~~~ buf.c: In function ‘next_line’: buf.c:848:1: warning: old-style function definition [-Wold-style-definition] 848 | next_line(line, num) | ^~~~~~~~~ buf.c: In function ‘prev_line’: buf.c:862:1: warning: old-style function definition [-Wold-style-definition] 862 | prev_line(line, num) | ^~~~~~~~~ make[2]: *** [<builtin>: commands.o] Error 1 make[2]: *** [<builtin>: buf.o] Error 1 make[2]: Leaving directory '/build/reproducible-path/jove-4.17.5.3' dh_auto_build: error: make -j8 "INSTALL=install --strip-program=true" SYSDEFS=-DLinux "OPTFLAGS=-g -O2 -Werror=implicit-function-declaration -ffile-prefix-map=/build/reproducible-path/jove-4.17.5.3=. -fstack-protector-strong -fstack-clash-protection -Wformat -Werror=format-security -fcf-protection" "LDLIBS=-lncurses -ltinfo -lutil" "LDFLAGS=-Wl,-z,relro -Wl,-z,now" JOVEHOME=/usr JMANDIR=/usr/share/man/man1 LOCALCC=x86_64-linux-gnu-gcc CC=x86_64-linux-gnu-gcc all returned exit code 2 make[1]: *** [debian/rules:20: override_dh_auto_build] Error 25 make[1]: Leaving directory '/build/reproducible-path/jove-4.17.5.3' make: *** [debian/rules:17: binary] Error 2 dpkg-buildpackage: error: debian/rules binary subprocess returned exit status 2
