Hello Reuben. I have received the report below from the Debian BTS.
I found a way to fix it in recode 3.6, and I assume that it is already fixed in recode 3.7.x (but I still have to check). So, this email is just to tell you that you were right in Bug #1066203 when you suggested to update the configure script. In such bug, I first tried adding missing includes (as many as required), and when I realized that there were too many of them, I gave up and disabled -Werror=implicit-function-declaration in debian/rules via DEB_CFLAGS_MAINT_STRIP. When using gcc-14, this is no longer possible so I had to look at this again. What I found is that running autoconf one more time produces a configure script which is a little bit smarter than before, and then I just had to add three missing includes. I still would like to see recode 3.7.x in trixie, but this will buy us a little bit more time. Thanks. -------- Mensaje reenviado -------- Asunto: Bug#1075440: recode: ftbfs with GCC-14 De: Matthias Klose <d...@debian.org> Package: src:recode Version: 3.6-26 Severity: important Tags: sid trixie User: debian-...@lists.debian.org Usertags: ftbfs-gcc-14 [This bug is 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-14/g++-14, but succeeds to build with gcc-13/g++-13. The severity of this report will be raised before the trixie release. The full build log can be found at: http://qa-logs.debian.net/2024/07/01/recode_3.6-26_unstable_gccexp.log The last lines of the build log are at the end of this report. To build with GCC 14, either set CC=gcc-14 CXX=g++-14 explicitly, or install the gcc, g++, gfortran, ... packages from experimental. apt-get -t=experimental install g++ Common build failures are new warnings resulting in build failures with -Werror turned on, or new/dropped symbols in Debian symbols files.
