-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Dear Debian developers,
Eigen is a widely used C++ template library for linear algebra (matrices, vectors, numerical solvers). Many packages in Debian across scientific, robotics, computer vision, geometry, and other domains depend on it via libeigen3-dev. I have filed 41 bugs against packages failing to build with libeigen3-dev 5.0.1 (currently in experimental); 39 are still open. Release notes for the new major version: https://libeigen.gitlab.io/releases/5.0/ The main breaking changes in 5.0: - C++14 is now the minimum required standard; packages still using -std=c++11 will fail to build. - The CMake integration has been modernized; older CMake properties may need updating. - Eigen::all and Eigen::last have moved to Eigen::placeholders::all and Eigen::placeholders::last. libeigen3-dev_5.0.1-1 is expected to be uploaded to unstable at the beginning of June 2026. At that point open FTBFS bugs will be raised to serious. All filed bugs are tagged: User: [email protected] Usertags: eigen3-5.0 Bug-Tracker: https://bugs.debian.org/cgi-bin/[email protected]&tag=eigen3-5.0 UDD: https://udd.debian.org/bugs/?release=any&merged=ign&done=ign&fnewerval=7&flastmodval=7&fusertag=only&fusertagtag=eigen3-5.0&fusertaguser=debian-devel%40lists.debian.org&allbugs=1&sortby=id&sorto=asc&format=html#results Please help to fix those bugs as much as possible to escape package removal from testing.
