[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/vrfy_990522-11_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 [...] | ^~~~~~~~ ~~~~ defs.h:51:5: note: declared here 51 | int smtpinit PROTO((char *)); | ^~~~~~~~ main.c:1585:25: error: too many arguments to function ‘smtphelo’; expected 0, have 2 1585 | reply = smtphelo(MyHostName, ehlomode); | ^~~~~~~~ ~~~~~~~~~~ defs.h:52:5: note: declared here 52 | int smtphelo PROTO((char *, bool)); | ^~~~~~~~ main.c: In function ‘getmxhosts’: main.c:1603:1: warning: old-style function definition [-Wold-style-definition] 1603 | getmxhosts(domain) | ^~~~~~~~~~ main.c:1605:1: error: number of arguments doesn’t match prototype 1605 | { | ^ defs.h:34:5: error: prototype declaration 34 | int getmxhosts PROTO((char *)); | ^~~~~~~~~~ main.c:1612:15: error: too many arguments to function ‘rindex’; expected 0, have 2 1612 | dot = rindex(domain, '.'); | ^~~~~~ ~~~~~~ defs.h:116:7: note: declared here 116 | char *rindex PROTO((const char *, int)); | ^~~~~~ main.c:1635:15: error: too many arguments to function ‘getmxbyname’; expected 0, have 1 1635 | nmx = getmxbyname(domain); | ^~~~~~~~~~~ ~~~~~~ defs.h:86:5: note: declared here 86 | int getmxbyname PROTO((char *)); | ^~~~~~~~~~~ main.c:1645:15: error: too many arguments to function ‘rindex’; expected 0, have 2 1645 | dot = rindex(domain, '.'); | ^~~~~~ ~~~~~~ defs.h:116:7: note: declared here 116 | char *rindex PROTO((const char *, int)); | ^~~~~~ main.c: In function ‘setsender’: main.c:1669:1: warning: old-style function definition [-Wold-style-definition] 1669 | setsender(address) | ^~~~~~~~~ main.c:1671:1: error: number of arguments doesn’t match prototype 1671 | { | ^ defs.h:35:7: error: prototype declaration 35 | char *setsender PROTO((char *)); | ^~~~~~~~~ main.c:1680:19: error: too many arguments to function ‘parselist’; expected 0, have 1 1680 | address = parselist(address); | ^~~~~~~~~ ~~~~~~~ defs.h:39:7: note: declared here 39 | char *parselist PROTO((char *)); | ^~~~~~~~~ main.c:1685:18: error: too many arguments to function ‘parsespec’; expected 0, have 3 1685 | domain = parsespec(address, addrbuf, (char *)NULL); | ^~~~~~~~~ ~~~~~~~ defs.h:40:7: note: declared here 40 | char *parsespec PROTO((char *, char *, char *)); | ^~~~~~~~~ main.c: At top level: main.c:39:13: warning: ‘Version’ defined but not used [-Wunused-variable] 39 | static char Version[] = "@(#)vrfy.c e07@nikhef.nl (Eric Wassenaar) 980820"; | ^~~~~~~ make[2]: *** [<builtin>: main.o] Error 1 make[2]: Leaving directory '/build/reproducible-path/vrfy-990522' make[1]: *** [debian/rules:7: override_dh_auto_build] Error 2 make[1]: Leaving directory '/build/reproducible-path/vrfy-990522' make: *** [debian/rules:16: binary] Error 2 dpkg-buildpackage: error: debian/rules binary subprocess returned exit status 2
