[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/iftop_1.0~pre4-9_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 [...] checking if we need to enable promiscuous mode by default... no checking that generated files are newer than configure... done configure: creating ./config.status config.status: creating Makefile config.status: creating config/Makefile config.status: creating config.h config.status: executing depfiles commands configure: WARNING: ****************************************************************************** This is a pre-release version. Pre-releases are subject to limited announcements, and therefore limited circulation, as a means of testing the more widely circulated final releases. Please do not be surprised if this release is broken, and if it is broken, do not assume that someone else has spotted it. Instead, please drop a note on the mailing list, or a brief email to me on pdw@ex-parrot.com Thank you for taking the time to be the testing phase of this development process.
