Package: src:bglibs Version: 2.04+dfsg-7 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/bglibs_2.04+dfsg-7_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 [...] 102 | extern int select (int __nfds, fd_set *__restrict __readfds, | ^~~~~~ unix/selfpipe.c: In function 'selfpipe_catch_signal': unix/selfpipe.c:19:3: warning: ignoring return value of 'write' declared with attribute 'warn_unused_result' [-Wunused-result] 19 | write(fds[1], &c, 1); | ^~~~~~~~~~~~~~~~~~~~ make[2]: *** [Makefile:1237: unix/selfpipe.lo] Error 1 make[2]: *** Waiting for unfinished jobs....
