I understand the need to fix the issue globally on the debhelper or meson side, and I have seen the bug #1042398. From my understanding we won't have a solution soon, and in the meantime pycairo is not buildable. This affects the riscv64 bootstrap, many packages are blocked behind this. Therefore I wonder if it should be possible to temporarily address the issue directly in pycairo by passing -Dpython.bytecompile=-1 at the configure step. I can offer to do a NMU if it can spare you some work. Regards Aurelien -- Aurelien Jarno GPG: 4096R/1DDD8C9B aurel...@aurel32.net http://aurel32.net

I think we probably want debhelper's meson build system backend (/usr/share/perl5/Debian/Debhelper/Buildsystem/meson.pm) to do this globally for all Meson-built packages, the same way it already handles cross-compilation, --prefix, --sysconfdir and so on, instead of having to do it per-package. Is there a way for debhelper to set this option without breaking the build of packages that contain no Python? smcv
Bug#1040748: ftbfs in pycairo with meson 1.2.0 rc2
Source: pycairo Version: 1.24.0-1 Severity: important Tags: ftbfs X-Debbugs-CC: hel...@subdivi.de During an archive rebuild against the release candidate for meson in experimental, pycairo failed to build from source with the following log excerpt: ``` dh_auto_install -O--buildsystem=meson cd obj-x86_64-linux-gnu && DESTDIR=/<>/debian/tmp LC_ALL=C.UTF-8 ninja install [0/1] Installing files. Compiling '/<>/debian/tmp/usr/lib/python3/dist-packages/cairo/__init__.py'... [...] Running custom install script '/usr/bin/python3 /<>/obj-x86_64-linux-gnu/meson-private/pycompile.py python-3.11-installed.json 0' [...] dh_missing -O--buildsystem=meson dh_missing: warning: usr/lib/python3/dist-packages/cairo/__pycache__/__init__.cpython-311.pyc exists in debian/tmp but is not installed to anywhere dh_missing: error: missing files, aborting [...] make: *** [debian/rules:6: binary] Error 25 ``` This fails with the release candidate, but does not fail against the stable release of meson. The underlying cause is an additional feature of meson: https://mesonbuild.com/Release-notes-for-1-2-0.html#python-module-can-now-compile-bytecode If this file is not desired in the debian package, please specify your preferred value for this meson setting. For example, to avoid compiling bytecode as part of `meson install`, you could setup the build system with the `-Dpython.bytecompile=-1` option. -- Eli Schwartz
