[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/racon_1.5.0-3_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 [...] | ^~~~ /build/reproducible-path/racon-1.5.0/src/window.cpp:93:23: error: invalid types ‘int[uint32_t {aka unsigned int}]’ for array subscript 93 | if (positions_[i].first < offset && positions_[i].second > | ^ /build/reproducible-path/racon-1.5.0/src/window.cpp:93:55: error: invalid types ‘int[uint32_t {aka unsigned int}]’ for array subscript 93 | if (positions_[i].first < offset && positions_[i].second > | ^ /build/reproducible-path/racon-1.5.0/src/window.cpp:94:24: error: request for member ‘front’ in ‘((racon::Window*)this)->racon::Window::sequences_’, which is of non-class type ‘int’ 94 | sequences_.front().second - offset) { | ^~~~~ /build/reproducible-path/racon-1.5.0/src/window.cpp:96:27: error: invalid types ‘int[uint32_t {aka unsigned int}]’ for array subscript 96 | sequences_[i].first, sequences_[i].second, | ^ /build/reproducible-path/racon-1.5.0/src/window.cpp:96:48: error: invalid types ‘int[uint32_t {aka unsigned int}]’ for array subscript 96 | sequences_[i].first, sequences_[i].second, | ^ /build/reproducible-path/racon-1.5.0/src/window.cpp:101:27: error: invalid types ‘int[uint32_t {aka unsigned int}]’ for array subscript 101 | positions_[i].first, | ^ /build/reproducible-path/racon-1.5.0/src/window.cpp:102:27: error: invalid types ‘int[uint32_t {aka unsigned int}]’ for array subscript 102 | positions_[i].second, | ^ /build/reproducible-path/racon-1.5.0/src/window.cpp:105:27: error: invalid types ‘int[uint32_t {aka unsigned int}]’ for array subscript 105 | sequences_[i].first, sequences_[i].second, | ^ /build/reproducible-path/racon-1.5.0/src/window.cpp:105:48: error: invalid types ‘int[uint32_t {aka unsigned int}]’ for array subscript 105 | sequences_[i].first, sequences_[i].second, | ^ /build/reproducible-path/racon-1.5.0/src/window.cpp:110:23: error: invalid types ‘int[uint32_t {aka unsigned int}]’ for array subscript 110 | if (qualities_[i].first == nullptr) { | ^ /build/reproducible-path/racon-1.5.0/src/window.cpp:113:27: error: invalid types ‘int[uint32_t {aka unsigned int}]’ for array subscript 113 | sequences_[i].first, sequences_[i].second); | ^ /build/reproducible-path/racon-1.5.0/src/window.cpp:113:48: error: invalid types ‘int[uint32_t {aka unsigned int}]’ for array subscript 113 | sequences_[i].first, sequences_[i].second); | ^ /build/reproducible-path/racon-1.5.0/src/window.cpp:117:27: error: invalid types ‘int[uint32_t {aka unsigned int}]’ for array subscript 117 | sequences_[i].first, sequences_[i].second, | ^ /build/reproducible-path/racon-1.5.0/src/window.cpp:117:48: error: invalid types ‘int[uint32_t {aka unsigned int}]’ for array subscript 117 | sequences_[i].first, sequences_[i].second, | ^ /build/reproducible-path/racon-1.5.0/src/window.cpp:118:27: error: invalid types ‘int[uint32_t {aka unsigned int}]’ for array subscript 118 | qualities_[i].first, qualities_[i].second); | ^ /build/reproducible-path/racon-1.5.0/src/window.cpp:118:48: error: invalid types ‘int[uint32_t {aka unsigned int}]’ for array subscript 118 | qualities_[i].first, qualities_[i].second); | ^ /build/reproducible-path/racon-1.5.0/src/window.cpp:126:49: error: request for member ‘size’ in ‘((racon::Window*)this)->racon::Window::sequences_’, which is of non-class type ‘int’ 126 | uint32_t average_coverage = (sequences_.size() - 1) / 2; | ^~~~ /build/reproducible-path/racon-1.5.0/src/window.cpp:142:65: error: ‘id_’ was not declared in this scope; did you mean ‘id_t’? 142 | "contig %lu might be chimeric in window %u!\n", id_, rank_); | ^~~ | id_t /build/reproducible-path/racon-1.5.0/src/window.cpp:142:70: error: ‘rank_’ was not declared in this scope; did you mean ‘rank’? 142 | "contig %lu might be chimeric in window %u!\n", id_, rank_); | ^~~~~ | rank make[3]: *** [CMakeFiles/racon.dir/build.make:138: CMakeFiles/racon.dir/src/window.cpp.o] Error 1 make[3]: *** Waiting for unfinished jobs.... make[3]: Leaving directory '/build/reproducible-path/racon-1.5.0/obj-x86_64-linux-gnu' make[2]: *** [CMakeFiles/Makefile2:96: CMakeFiles/racon.dir/all] Error 2 make[2]: Leaving directory '/build/reproducible-path/racon-1.5.0/obj-x86_64-linux-gnu' make[1]: *** [Makefile:159: all] Error 2 make[1]: Leaving directory '/build/reproducible-path/racon-1.5.0/obj-x86_64-linux-gnu' dh_auto_build: error: cd obj-x86_64-linux-gnu && make -j8 "INSTALL=install --strip-program=true" VERBOSE=1 returned exit code 2 make: *** [debian/rules:12: binary] Error 25 dpkg-buildpackage: error: debian/rules binary subprocess returned exit status 2
