[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/xzgv_0.9.2-2_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 [...] | ^~~~~~~~~~ In file included from /usr/include/gtk-2.0/gtk/gtktoolitem.h:31, from /usr/include/gtk-2.0/gtk/gtktoolbutton.h:30, from /usr/include/gtk-2.0/gtk/gtkmenutoolbutton.h:30, from /usr/include/gtk-2.0/gtk/gtk.h:126: /usr/include/gtk-2.0/gtk/gtktooltips.h:73:3: warning: ‘GTimeVal’ is deprecated: Use 'GDateTime' instead [-Wdeprecated-declarations] 73 | GTimeVal last_popdown;
