[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/pdns_4.9.4-1_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 [...] 50 | std::string hashPassword(const std::string& password, uint64_t workFactor, uint64_t parallelFactor, uint64_t blockSize); | ^~~~~~~~ credentials.hh:50:101: note: ‘uint64_t’ is defined in header ‘<cstdint>’; this is probably fixable by adding ‘#include <cstdint>’ credentials.hh:52:77: error: ‘uint64_t’ has not been declared 52 | bool verifyPassword(const std::string& binaryHash, const std::string& salt, uint64_t workFactor, uint64_t parallelFactor, uint64_t blockSize, const std::string& binaryPassword); | ^~~~~~~~ credentials.hh:52:77: note: ‘uint64_t’ is defined in header ‘<cstdint>’; this is probably fixable by adding ‘#include <cstdint>’ credentials.hh:52:98: error: ‘uint64_t’ has not been declared 52 | bool verifyPassword(const std::string& binaryHash, const std::string& salt, uint64_t workFactor, uint64_t parallelFactor, uint64_t blockSize, const std::string& binaryPassword); | ^~~~~~~~ credentials.hh:52:98: note: ‘uint64_t’ is defined in header ‘<cstdint>’; this is probably fixable by adding ‘#include <cstdint>’ credentials.hh:52:123: error: ‘uint64_t’ has not been declared 52 | bool verifyPassword(const std::string& binaryHash, const std::string& salt, uint64_t workFactor, uint64_t parallelFactor, uint64_t blockSize, const std::string& binaryPassword); | ^~~~~~~~ credentials.hh:52:123: note: ‘uint64_t’ is defined in header ‘<cstdint>’; this is probably fixable by adding ‘#include <cstdint>’ credentials.hh:84:10: error: ‘uint64_t’ does not name a type 84 | static uint64_t const s_defaultWorkFactor; | ^~~~~~~~ credentials.hh:84:10: note: ‘uint64_t’ is defined in header ‘<cstdint>’; this is probably fixable by adding ‘#include <cstdint>’ credentials.hh:85:10: error: ‘uint64_t’ does not name a type 85 | static uint64_t const s_defaultParallelFactor; | ^~~~~~~~ credentials.hh:85:10: note: ‘uint64_t’ is defined in header ‘<cstdint>’; this is probably fixable by adding ‘#include <cstdint>’ credentials.hh:86:10: error: ‘uint64_t’ does not name a type 86 | static uint64_t const s_defaultBlockSize; | ^~~~~~~~ credentials.hh:86:10: note: ‘uint64_t’ is defined in header ‘<cstdint>’; this is probably fixable by adding ‘#include <cstdint>’ credentials.hh:93:3: error: ‘uint64_t’ does not name a type 93 | uint64_t d_workFactor{0}; | ^~~~~~~~ credentials.hh:93:3: note: ‘uint64_t’ is defined in header ‘<cstdint>’; this is probably fixable by adding ‘#include <cstdint>’ credentials.hh:94:3: error: ‘uint64_t’ does not name a type 94 | uint64_t d_parallelFactor{0}; | ^~~~~~~~ credentials.hh:94:3: note: ‘uint64_t’ is defined in header ‘<cstdint>’; this is probably fixable by adding ‘#include <cstdint>’ credentials.hh:95:3: error: ‘uint64_t’ does not name a type 95 | uint64_t d_blockSize{0}; | ^~~~~~~~ credentials.hh:95:3: note: ‘uint64_t’ is defined in header ‘<cstdint>’; this is probably fixable by adding ‘#include <cstdint>’ credentials.hh:97:3: error: ‘uint32_t’ does not name a type 97 | uint32_t d_fallbackHashPerturb{0}; | ^~~~~~~~ credentials.hh:97:3: note: ‘uint32_t’ is defined in header ‘<cstdint>’; this is probably fixable by adding ‘#include <cstdint>’ credentials.hh:98:3: error: ‘uint32_t’ does not name a type 98 | uint32_t d_fallbackHash{0}; | ^~~~~~~~ credentials.hh:98:3: note: ‘uint32_t’ is defined in header ‘<cstdint>’; this is probably fixable by adding ‘#include <cstdint>’ make[4]: *** [Makefile:3376: ixfrdist-web.o] Error 1 make[4]: *** Waiting for unfinished jobs....
