The upstream released a new major version of this mathematical library, 5.0.0. Some basic information about new features and changes in this version can be found here: https://libeigen.gitlab.io/releases/5.0/ This is a major version change and may require code changes in packages depending on eigen3. The key breaking changes include: - Minimum required C++ standard is now C++14 - Changes in the build system integration - Some API name changes openbabel FTBFS with libeigen3-dev 5.0.1. The full build log is available at: https://debusine.debian.net/debian/developers-gladk-eigen3/artifact/3759397/ Here is the most probably relevant part of the failing build log: =========================================== - -- Detecting CXX compile features - done - -- Eigen version .. found in /usr/include/eigen3, but at least version 2.91.0 is required CMake Error at /usr/share/cmake-4.3/Modules/FindPackageHandleStandardArgs.cmake:290 (message): Could NOT find Eigen (missing: EIGEN_VERSION_OK) (Required is at least version "2.91.0") Call Stack (most recent call first): /usr/share/cmake-4.3/Modules/FindPackageHandleStandardArgs.cmake:654 (_FPHSA_FAILURE_MESSAGE) modules/FindEigen.cmake:76 (find_package_handle_standard_args) CMakeLists.txt:49 (find_package) - -- Configuring incomplete, errors occurred! cd .pybuild/cpython3_3.14/build && tail -v -n \+0 CMakeCache.txt ==> CMakeCache.txt <== # This is the CMakeCache file. # For build in directory: /build/reproducible-path/opengv-1.0+1git91f4b1/.pybuild/cpython3_3.14/build # It was generated by CMake: /usr/bin/cmake # You can edit this file to change values found and used by cmake. # If you do not want to change any of the values, simply exit the editor. # If you do want to change a value, simply edit, save, and exit the editor. # The syntax for the file is as follows: # KEY:TYPE=VALUE # KEY is the name of a variable in the cache. # TYPE is a hint to GUIs for the type of VALUE, DO NOT EDIT TYPE!. # VALUE is the current value for the KEY. =========================================== libeigen3-dev_5.0.1-1 is available in experimental. When this package version lands into unstable (probably at the beginning of June 2026), this bug will be increased in severity to serious.
