I'm having trouble building libSavitar 5.0-beta (part of Cura, a slicer for 3d printers): <https://github.com/Ultimaker/libsavitar/tree/5.0-beta> When building with sip 6.6.1+dfsg-1 it fails with this traceback: '/usr/bin/cmake' '-E' 'env' 'PYTHONPATH=::/home/seb/cura-debs/libsavitar-docker-sandbox/.pybuild/cpython3_3.9/build' '/usr/bin/sip-build' '--pep484-pyi' '--no-protected-is-public' '--verbose' Using the CMake builder These bindings will be built: pySavitar.

The problem is present in upstream, and is due to upstream's ongoing effort to switch from parsing with bison & flex, to parsing with PLY instead. The new pure-python parser is not quite fully functional yet. (The sip 6.5 in testing still uses the old bison/flex-based parser.) After applying patches from upstream's mercurial repo, r2748 through r2761, the parser now successfully handles libSavitar 5.0-beta. Here is a gbp branch with these changes from upstream applied: https://salsa.debian.org/seb_kuzminsky-guest/sip6/-/commits/debian/master/ That probably isn't in the correct format, if you give me feedback i'll try to fix it, or feel free to do with it what you will. We may also want to consider staying on sip 6.5 for a while, until the new parser is more mature, but I defer to your judgement on this. -- System Information: Debian Release: 11.3 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable-security'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 5.10.0-14-rt-amd64 (SMP w/12 CPU threads; PREEMPT) Kernel taint flags: TAINT_WARN Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled
