[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/aprx_2.9.1-3_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 [...] interface.c:1824:52: warning: format ‘%p’ expects argument of type ‘void *’, but argument 2 has type ‘const struct aprx_interface *’ [-Wformat=] 1824 | printf("interface_transmit_beacon() aif=%p, aif->txok=%d aif->callsign='%s'\n", | ~^ | | | void * 1825 | aif, aif && aif->tx_ok ? 1 : 0, aif ? aif->callsign : "<nil>"); | ~~~ | | | const struct aprx_interface * pbuf.c: In function ‘pbuf_free’: pbuf.c:57:43: warning: format ‘%p’ expects argument of type ‘void *’, but argument 2 has type ‘struct pbuf_t *’ [-Wformat=] 57 | if (debug > 1) printf("pbuf_free(%p)\n",pb); | ~^ ~~ | | | | | struct pbuf_t * | void * pbuf.c: In function ‘pbuf_alloc’: pbuf.c:81:54: warning: format ‘%p’ expects argument of type ‘void *’, but argument 4 has type ‘struct pbuf_t *’ [-Wformat=] 81 | if (debug > 1) printf("pbuf_alloc(%d,%d) -> %p\n",axlen,tnc2len,pb); | ~^ ~~ | | | | void * struct pbuf_t * make[1]: *** [Makefile:142: interface.o] Error 1 make[1]: *** Waiting for unfinished jobs.... digipeater.c: In function ‘digipeater_config_source’: digipeater.c:745:59: warning: format ‘%p’ expects argument of type ‘void *’, but argument 2 has type ‘struct aprx_interface *’ [-Wformat=] 745 | printf(" .. source_aif = %p\n", source_aif); | ~^ ~~~~~~~~~~ | | | | | struct aprx_interface * | void * digipeater.c:954:64: warning: format ‘%p’ expects argument of type ‘void *’, but argument 2 has type ‘struct digipeater_source *’ [-Wformat=] 954 | if (debug>1)printf(" .. <source> definition returning %p\n",source); | ~^ ~~~~~~ | | | | | struct digipeater_source * | void * digipeater.c: In function ‘digipeater_receive’: digipeater.c:1668:82: warning: format ‘%p’ expects argument of type ‘void *’, but argument 4 has type ‘struct pbuf_t *’ [-Wformat=] 1668 | if (debug) printf("%ld ENTER VISCOUS QUEUE: len=%d pbuf=%p\n", | ~^ | | | void * 1669 | tick.tv_sec, src->viscous_queue_size, pb); | ~~ | | | struct pbuf_t * digipeater.c: In function ‘digipeater_postpoll’: digipeater.c:1795:90: warning: format ‘%p’ expects argument of type ‘void *’, but argument 3 has type ‘struct dupe_record_t *’ [-Wformat=] 1795 | if (debug)printf("%ld LEAVE VISCOUS QUEUE: dupe=%p pbuf=%p\n", | ~^ | | | void * 1796 | tick.tv_sec, dupe, dupe->pbuf); | ~~~~ | | | struct dupe_record_t * digipeater.c:1795:98: warning: format ‘%p’ expects argument of type ‘void *’, but argument 4 has type ‘struct pbuf_t *’ [-Wformat=] 1795 | if (debug)printf("%ld LEAVE VISCOUS QUEUE: dupe=%p pbuf=%p\n", | ~^ | | | void * 1796 | tick.tv_sec, dupe, dupe->pbuf); | ~~~~~~~~~~ | | | struct pbuf_t * make[1]: Leaving directory '/build/reproducible-path/aprx-2.9.1' dh_auto_build: error: make -j8 returned exit code 2 make: *** [debian/rules:23: binary] Error 25 dpkg-buildpackage: error: debian/rules binary subprocess returned exit status 2
