Package: src:giftrans Version: 1.12.2-20 Severity: important Tags: sid forky User: [email protected] 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/giftrans_1.12.2-20_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 [...] giftrans.c: In function ‘main’: giftrans.c:793:5: warning: old-style function definition [-Wold-style-definition] 793 | int main(argc,argv) | ^~~~ giftrans.c: In function ‘skipdata’: giftrans.c:293:23: warning: ignoring return value of ‘fread’ declared with attribute ‘warn_unused_result’ [-Wunused-result] 293 | (void)fread((void *)&size,1,1,src); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~ giftrans.c:298:31: warning: ignoring return value of ‘fread’ declared with attribute ‘warn_unused_result’ [-Wunused-result] 298 | (void)fread((void *)buffer,(size_t)size,1,src); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ giftrans.c: In function ‘transblock’: giftrans.c:314:15: warning: ignoring return value of ‘fread’ declared with attribute ‘warn_unused_result’ [-Wunused-result] 314 | (void)fread((void *)&size,1,1,src); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~ giftrans.c:320:15: warning: ignoring return value of ‘fread’ declared with attribute ‘warn_unused_result’ [-Wunused-result] 320 | (void)fread((void *)buffer,(size_t)size,1,src); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ giftrans.c: In function ‘dumpcomment’: giftrans.c:335:15: warning: ignoring return value of ‘fread’ declared with attribute ‘warn_unused_result’ [-Wunused-result] 335 | (void)fread((void *)&size,1,1,src); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~ giftrans.c:338:15: warning: ignoring return value of ‘fread’ declared with attribute ‘warn_unused_result’ [-Wunused-result] 338 | (void)fread((void *)buffer,(size_t)size,1,src); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ giftrans.c: In function ‘transdata’: giftrans.c:366:23: warning: ignoring return value of ‘fread’ declared with attribute ‘warn_unused_result’ [-Wunused-result] 366 | (void)fread((void *)&size,1,1,src); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~ giftrans.c:372:23: warning: ignoring return value of ‘fread’ declared with attribute ‘warn_unused_result’ [-Wunused-result] 372 | (void)fread((void *)buffer,(size_t)size,1,src); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ giftrans.c: In function ‘giftrans’: giftrans.c:392:15: warning: ignoring return value of ‘fread’ declared with attribute ‘warn_unused_result’ [-Wunused-result] 392 | (void)fread((void *)buffer,6,1,src); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ giftrans.c:411:15: warning: ignoring return value of ‘fread’ declared with attribute ‘warn_unused_result’ [-Wunused-result] 411 | (void)fread((void *)lsd,7,1,src); | ^~~~~~~~~~~~~~~~~~~~~~~~~~ giftrans.c:434:23: warning: ignoring return value of ‘fread’ declared with attribute ‘warn_unused_result’ [-Wunused-result] 434 | (void)fread((void *)gct,gct_size,3,src); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ giftrans.c:492:23: warning: ignoring return value of ‘fread’ declared with attribute ‘warn_unused_result’ [-Wunused-result] 492 | (void)fread((void *)buffer,1,1,src); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ giftrans.c:497:31: warning: ignoring return value of ‘fread’ declared with attribute ‘warn_unused_result’ [-Wunused-result] 497 | (void)fread((void *)(buffer+1),9,1,src); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ giftrans.c:553:39: warning: ignoring return value of ‘fread’ declared with attribute ‘warn_unused_result’ [-Wunused-result] 553 | (void)fread((void *)buffer,size,3,src); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ giftrans.c:571:31: warning: ignoring return value of ‘fread’ declared with attribute ‘warn_unused_result’ [-Wunused-result] 571 | (void)fread((void *)buffer,1,1,src); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ giftrans.c:596:31: warning: ignoring return value of ‘fread’ declared with attribute ‘warn_unused_result’ [-Wunused-result] 596 | (void)fread((void *)(buffer+1),1,1,src); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ giftrans.c:617:39: warning: ignoring return value of ‘fread’ declared with attribute ‘warn_unused_result’ [-Wunused-result] 617 | (void)fread((void *)(buffer+2),1,1,src); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ giftrans.c:622:39: warning: ignoring return value of ‘fread’ declared with attribute ‘warn_unused_result’ [-Wunused-result] 622 | (void)fread((void *)gce,size,1,src); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ giftrans.c:652:39: warning: ignoring return value of ‘fread’ declared with attribute ‘warn_unused_result’ [-Wunused-result] 652 | (void)fread((void *)buffer,1,1,src); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ make[1]: *** [debian/rules:11: override_dh_auto_build] Error 1 make[1]: Leaving directory '/build/reproducible-path/giftrans-1.12.2' make: *** [debian/rules:8: binary] Error 2 dpkg-buildpackage: error: debian/rules binary subprocess returned exit status 2
