Package: src:brotli Version: 1.2.0-3 Severity: serious Architecture: armhf arm64 User: [email protected] Usertags: python3.15
Hi! While rebuilding packages against Python 3.15 we found that brotli failed to build from source in arm64. This issue is unrelated to Python 3.15, but instead triggered by a change in debhelper that now is passing the -DCMAKE_C_COMPILER option, and brotli uses regular expressions on that variable to decide that the build is being crosscompiled, trying to use qemu (which is not a build dependency), causing the FTBFS. I'm attaching the patch that I'm applying in my sandbox to be able to build the packages that depend on brotli, please consider applying a similar patch or add qemu-user to the build dependencies in the corresponding architectures (not ideal). Happy hacking, -- Porque no respeta el orden natural en el que se leen las cosas
