[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/wise_2.4.1-25_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 [...] 4344 | group_match_null_string_p (p, end, reg_info) | ^~~~~~~~~~~~~~~~~~~~~~~~~ gnuregex.c:4394:24: error: too many arguments to function ‘alt_match_null_string_p’; expected 0, have 3 4394 | if (!alt_match_null_string_p (p1, p1 + mcnt - 3, | ^~~~~~~~~~~~~~~~~~~~~~~ ~~ gnuregex.c:2982:16: note: declared here 2982 | static boolean alt_match_null_string_p (), | ^~~~~~~~~~~~~~~~~~~~~~~ gnuregex.c:4424:20: error: too many arguments to function ‘alt_match_null_string_p’; expected 0, have 3 4424 | if (!alt_match_null_string_p (p1, p1 + mcnt, reg_info)) | ^~~~~~~~~~~~~~~~~~~~~~~ ~~ gnuregex.c:2982:16: note: declared here 2982 | static boolean alt_match_null_string_p (), | ^~~~~~~~~~~~~~~~~~~~~~~ gnuregex.c:4439:16: error: too many arguments to function ‘common_op_match_null_string_p’; expected 0, have 3 4439 | if (!common_op_match_null_string_p (&p1, end, reg_info)) | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~ gnuregex.c:2983:16: note: declared here 2983 | common_op_match_null_string_p (), | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ gnuregex.c: In function ‘alt_match_null_string_p’: gnuregex.c:4453:1: warning: old-style function definition [-Wold-style-definition] 4453 | alt_match_null_string_p (p, end, reg_info) | ^~~~~~~~~~~~~~~~~~~~~~~ gnuregex.c:4475:16: error: too many arguments to function ‘common_op_match_null_string_p’; expected 0, have 3 4475 | if (!common_op_match_null_string_p (&p1, end, reg_info)) | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~ gnuregex.c:2983:16: note: declared here 2983 | common_op_match_null_string_p (), | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ gnuregex.c: In function ‘common_op_match_null_string_p’: gnuregex.c:4490:1: warning: old-style function definition [-Wold-style-definition] 4490 | common_op_match_null_string_p (p, end, reg_info) | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ gnuregex.c:4520:13: error: too many arguments to function ‘group_match_null_string_p’; expected 0, have 3 4520 | ret = group_match_null_string_p (&p1, end, reg_info); | ^~~~~~~~~~~~~~~~~~~~~~~~~ ~~~ gnuregex.c:4344:1: note: declared here 4344 | group_match_null_string_p (p, end, reg_info) | ^~~~~~~~~~~~~~~~~~~~~~~~~ gnuregex.c: In function ‘bcmp_translate’: gnuregex.c:4578:1: warning: old-style function definition [-Wold-style-definition] 4578 | bcmp_translate (s1, s2, len, translate) | ^~~~~~~~~~~~~~ gnuregex.c: In function ‘regcomp’: gnuregex.c:4720:1: warning: old-style function definition [-Wold-style-definition] 4720 | regcomp (preg, pattern, cflags) | ^~~~~~~ gnuregex.c: In function ‘regexec’: gnuregex.c:4795:1: warning: old-style function definition [-Wold-style-definition] 4795 | regexec (preg, string, nmatch, pmatch, eflags) | ^~~~~~~ gnuregex.c: In function ‘regerror’: gnuregex.c:4860:1: warning: old-style function definition [-Wold-style-definition] 4860 | regerror (errcode, preg, errbuf, errbuf_size) | ^~~~~~~~ gnuregex.c: In function ‘regfree’: gnuregex.c:4904:1: warning: old-style function definition [-Wold-style-definition] 4904 | regfree (preg) | ^~~~~~~ make[3]: *** [Makefile:69: gnuregex.o] Error 1 make[3]: *** Waiting for unfinished jobs.... make[3]: Leaving directory '/build/reproducible-path/wise-2.4.1/src/HMMer2' make[2]: *** [makefile:89: realall] Error 2 make[2]: Leaving directory '/build/reproducible-path/wise-2.4.1/src' dh_auto_build: error: cd src && make -j8 "INSTALL=install --strip-program=true" all returned exit code 2 make[1]: *** [debian/rules:40: override_dh_auto_build] Error 25 make[1]: Leaving directory '/build/reproducible-path/wise-2.4.1' make: *** [debian/rules:32: binary] Error 2 dpkg-buildpackage: error: debian/rules binary subprocess returned exit status 2
