Package: src:dvbtune Version: 0.5.ds-5 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/dvbtune_0.5.ds-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 [...] make -j8 "INSTALL=install --strip-program=true" VERSION=0.5 "EXTRA_CFLAGS=-g -O2 -Werror=implicit-function-declaration -ffile-prefix-map=/build/reproducible-path/dvbtune-0.5.ds=. -fstack-protector-strong -fstack-clash-protection -Wformat -Werror=format-security -fcf-protection" make[2]: Entering directory '/build/reproducible-path/dvbtune-0.5.ds' gcc -g -Wall -I /usr/include/libxml2 -I ../DVB/include -DVERSION=\"0.5\" -g -O2 -Werror=implicit-function-declaration -ffile-prefix-map=/build/reproducible-path/dvbtune-0.5.ds=. -fstack-protector-strong -fstack-clash-protection -Wformat -Werror=format-security -fcf-protection -DNEWSTRUCT -Wdate-time -D_FORTIFY_SOURCE=2 -c -o tune.o tune.c In file included from tune.h:25, from tune.c:41: dvb_defaults.h:83:2: warning: #warning No DVB-T country defined in dvb_defaults.h [-Wcpp] 83 | #warning No DVB-T country defined in dvb_defaults.h | ^~~~~~~ dvb_defaults.h:84:2: warning: #warning defaulting to UK [-Wcpp] 84 | #warning defaulting to UK | ^~~~~~~ dvb_defaults.h:85:2: warning: #warning Ignore this if using Satellite or Cable [-Wcpp] 85 | #warning Ignore this if using Satellite or Cable | ^~~~~~~ tune.c: In function ‘check_status’: tune.c:252:21: warning: ‘fe_info.type’ may be used uninitialized [-Wmaybe-uninitialized] 252 | switch(fe_info.type) { | ~~~~~~~^~~~~ tune.c:219:28: note: ‘fe_info’ declared here 219 | struct dvb_frontend_info fe_info; | ^~~~~~~ gcc -g -Wall -I /usr/include/libxml2 -I ../DVB/include -DVERSION=\"0.5\" -g -O2 -Werror=implicit-function-declaration -ffile-prefix-map=/build/reproducible-path/dvbtune-0.5.ds=. -fstack-protector-strong -fstack-clash-protection -Wformat -Werror=format-security -fcf-protection -DNEWSTRUCT -Wdate-time -D_FORTIFY_SOURCE=2 -Wl,-z,relro dvbtune.c tune.o -o dvbtune In file included from tune.h:25, from dvbtune.c:82: dvb_defaults.h:83:2: warning: #warning No DVB-T country defined in dvb_defaults.h [-Wcpp] 83 | #warning No DVB-T country defined in dvb_defaults.h | ^~~~~~~ dvb_defaults.h:84:2: warning: #warning defaulting to UK [-Wcpp] 84 | #warning defaulting to UK | ^~~~~~~ dvb_defaults.h:85:2: warning: #warning Ignore this if using Satellite or Cable [-Wcpp] 85 | #warning Ignore this if using Satellite or Cable | ^~~~~~~ dvbtune.c: In function ‘scan_nit’: dvbtune.c:717:16: warning: variable ‘network_id’ set but not used [-Wunused-but-set-variable] 717 | int info_len,network_id; | ^~~~~~~~~~ dvbtune.c: In function ‘main’: dvbtune.c:1393:15: error: too many arguments to function ‘get_unscanned’; expected 0, have 1 1393 | while ((t=get_unscanned(transponders))!=NULL) { | ^~~~~~~~~~~~~ ~~~~~~~~~~~~ dvbtune.c:140:17: note: declared here 140 | transponder_t* get_unscanned() { | ^~~~~~~~~~~~~ dvbtune.c:1473:40: warning: pointer targets in passing argument 2 of ‘FEReadBER’ differ in signedness [-Wpointer-sign] 1473 | FEReadBER(fd_frontend, &ber); | ^~~~ | | | int32_t * {aka int *} dvbtune.c:1025:33: note: expected ‘uint32_t *’ {aka ‘unsigned int *’} but argument is of type ‘int32_t *’ {aka ‘int *’} 1025 | int FEReadBER(int fd, uint32_t *ber) | ~~~~~~~~~~^~~ dvbtune.c:1476:54: warning: pointer targets in passing argument 2 of ‘FEReadUncorrectedBlocks’ differ in signedness [-Wpointer-sign] 1476 | FEReadUncorrectedBlocks(fd_frontend, &uncorr); | ^~~~~~~ | | | int32_t * {aka int *} dvbtune.c:1073:47: note: expected ‘uint32_t *’ {aka ‘unsigned int *’} but argument is of type ‘int32_t *’ {aka ‘int *’} 1073 | int FEReadUncorrectedBlocks(int fd, uint32_t *ucb) | ~~~~~~~~~~^~~ dvbtune.c:1165:7: warning: variable ‘count’ set but not used [-Wunused-but-set-variable] 1165 | int count; | ^~~~~ make[2]: *** [<builtin>: dvbtune] Error 1 make[2]: Leaving directory '/build/reproducible-path/dvbtune-0.5.ds' dh_auto_build: error: make -j8 "INSTALL=install --strip-program=true" VERSION=0.5 "EXTRA_CFLAGS=-g -O2 -Werror=implicit-function-declaration -ffile-prefix-map=/build/reproducible-path/dvbtune-0.5.ds=. -fstack-protector-strong -fstack-clash-protection -Wformat -Werror=format-security -fcf-protection" returned exit code 2 make[1]: *** [debian/rules:10: override_dh_auto_build] Error 25 make[1]: Leaving directory '/build/reproducible-path/dvbtune-0.5.ds' make: *** [debian/rules:6: binary] Error 2 dpkg-buildpackage: error: debian/rules binary subprocess returned exit status 2
