Package: src:splitvt Version: 1.6.6-17 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/splitvt_1.6.6-17_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 [...] 736 | static void move_bar(howfar) | ^~~~~~~~ splitvt.c:748:9: error: too many arguments to function ‘init_vt100’; expected 0, have 1 748 | init_vt100(0); /* Reset the windows to the new size */ | ^~~~~~~~~~ ~ vt100.h:4:14: note: declared here 4 | extern char *init_vt100(); /* Initialize the window */ | ^~~~~~~~~~ splitvt.c: In function ‘winch’: splitvt.c:763:13: warning: old-style function definition [-Wold-style-definition] 763 | static void winch(sig) | ^~~~~ splitvt.c:768:21: error: passing argument 2 of ‘signal’ from incompatible pointer type [-Wincompatible-pointer-types] 768 | signal(sig, winch); | ^~~~~ | | | 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) | ~~~~~~~~~~~~~~~^~~~~~~~~ splitvt.c:763:13: note: ‘winch’ declared here 763 | static void winch(sig) | ^~~~~ /usr/include/signal.h:72:16: note: ‘__sighandler_t’ declared here 72 | typedef void (*__sighandler_t) (int); | ^~~~~~~~~~~~~~ splitvt.c:770:19: error: too many arguments to function ‘init_vt100’; expected 0, have 1 770 | if ( (ptr=init_vt100(1)) != NULL ) { | ^~~~~~~~~~ ~ vt100.h:4:14: note: declared here 4 | extern char *init_vt100(); /* Initialize the window */ | ^~~~~~~~~~ splitvt.c:772:17: error: too many arguments to function ‘finish’; expected 0, have 1 772 | finish(0); | ^~~~~~ ~ splitvt.c:709:13: note: declared here 709 | static void finish(sig) | ^~~~~~ splitvt.h:19:25: error: too many arguments to function ‘set_win’; expected 0, have 1 19 | #define SET_WIN() set_win(CUR_WIN()) | ^~~~~~~ splitvt.c:774:17: note: in expansion of macro ‘SET_WIN’ 774 | SET_WIN(); | ^~~~~~~ vt100.h:5:14: note: declared here 5 | extern void set_win(); /* Move the cursor to current window */ | ^~~~~~~ splitvt.c: In function ‘insert_dash’: splitvt.c:781:12: warning: old-style function definition [-Wold-style-definition] 781 | static int insert_dash(args) | ^~~~~~~~~~~ splitvt.c: In function ‘main’: splitvt.c:450:57: warning: ignoring return value of ‘write’ declared with attribute ‘warn_unused_result’ [-Wunused-result] 450 | write(thisfd, selection, strlen(selection)); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ splitvt.c: In function ‘normal_input’: splitvt.c:546:17: warning: ignoring return value of ‘read’ declared with attribute ‘warn_unused_result’ [-Wunused-result] 546 | read(ttyfd, &c, 1); | ^~~~~~~~~~~~~~~~~~ splitvt.c:591:35: warning: ignoring return value of ‘write’ declared with attribute ‘warn_unused_result’ [-Wunused-result] 591 | write(thisfd, selection, strlen(selection)); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ splitvt.c:625:17: warning: ignoring return value of ‘write’ declared with attribute ‘warn_unused_result’ [-Wunused-result] 625 | write(thisfd, &c, 1); | ^~~~~~~~~~~~~~~~~~~~ make[1]: *** [<builtin>: splitvt.o] Error 1 make[1]: Leaving directory '/build/reproducible-path/splitvt-1.6.6' dh_auto_build: error: make -j8 returned exit code 2 make: *** [debian/rules:7: build] Error 25 dpkg-buildpackage: error: debian/rules build subprocess returned exit status 2
