Package: src:flip Version: 1.20-5 Severity: important Tags: sid forky User: debian-...@lists.debian.org Usertags: ftbfs-gcc-15
[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/flip_1.20-5_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 [...] /usr/include/signal.h:72:16: note: ‘__sighandler_t’ declared here 72 | typedef void (*__sighandler_t) (int); | ^~~~~~~~~~~~~~ flip.c:540:24: error: passing argument 2 of ‘signal’ from incompatible pointer type [-Wincompatible-pointer-types] 540 | signal (SIGTERM, cleanup); | ^~~~~~~ | | | void (*)(void) /usr/include/signal.h:88:57: note: expected ‘__sighandler_t’ {aka ‘void (*)(int)’} but argument is of type ‘void (*)(void)’ 88 | extern __sighandler_t signal (int __sig, __sighandler_t __handler) | ~~~~~~~~~~~~~~~^~~~~~~~~ flip.c:35:6: note: ‘cleanup’ declared here 35 | void cleanup PARMS ((int)); | ^~~~~~~ /usr/include/signal.h:72:16: note: ‘__sighandler_t’ declared here 72 | typedef void (*__sighandler_t) (int); | ^~~~~~~~~~~~~~ flip.c: In function ‘cleanup’: flip.c:545:6: warning: old-style function definition [-Wold-style-definition] 545 | void cleanup(sig) | ^~~~~~~ flip.c:547:1: error: number of arguments doesn’t match prototype 547 | { | ^ flip.c:35:6: error: prototype declaration 35 | void cleanup PARMS ((int)); | ^~~~~~~ flip.c:550:17: error: passing argument 2 of ‘signal’ from incompatible pointer type [-Wincompatible-pointer-types] 550 | signal (sig, cleanup); /* ditto */ | ^~~~~~~ | | | void (*)(void) /usr/include/signal.h:88:57: note: expected ‘__sighandler_t’ {aka ‘void (*)(int)’} but argument is of type ‘void (*)(void)’ 88 | extern __sighandler_t signal (int __sig, __sighandler_t __handler) | ~~~~~~~~~~~~~~~^~~~~~~~~ flip.c:545:6: note: ‘cleanup’ declared here 545 | void cleanup(sig) | ^~~~~~~ /usr/include/signal.h:72:16: note: ‘__sighandler_t’ declared here 72 | typedef void (*__sighandler_t) (int); | ^~~~~~~~~~~~~~ flip.c: In function ‘error’: flip.c:557:6: warning: old-style function definition [-Wold-style-definition] 557 | void error (msg1, msg2) | ^~~~~ flip.c:559:1: error: number of arguments doesn’t match prototype 559 | { | ^ flip.c:33:6: error: prototype declaration 33 | void error PARMS ((char *, char *)); | ^~~~~ flip.c: In function ‘flip_exit’: flip.c:612:6: warning: old-style function definition [-Wold-style-definition] 612 | void flip_exit(stat) | ^~~~~~~~~ flip.c:614:1: error: number of arguments doesn’t match prototype 614 | { | ^ flip.c:26:6: error: prototype declaration 26 | void flip_exit PARMS ((int)); | ^~~~~~~~~ flip.c: At top level: flip.c:3:13: warning: ‘sccsid’ defined but not used [-Wunused-variable] 3 | static char sccsid[]="::[[ @(#) flip.c 1.20 2008-07-26 ]]::"; | ^~~~~~ make[1]: *** [Makefile:72: flip.o] Error 1 make[1]: Leaving directory '/build/reproducible-path/flip-1.20' dh_auto_build: error: make -j8 "INSTALL=install --strip-program=true" returned exit code 2 make: *** [debian/rules:23: binary] Error 25 dpkg-buildpackage: error: debian/rules binary subprocess returned exit status 2
