Dear Maintainer,
your package depends on libeigen3-dev. 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
dolfin FTBFS with libeigen3-dev 5.0.1. The full build log is available at:
https://debusine.debian.net/debian/developers-gladk-eigen3/artifact/3755404/
Here is the most probably relevant part of the failing build log:
===========================================
- -- Eigen3 version .. found in /usr/include/eigen3, but at least version
3.2.90 is required
CMake Error at
/usr/share/cmake-4.3/Modules/FindPackageHandleStandardArgs.cmake:290 (message):
Could NOT find Eigen3 (missing: EIGEN3_VERSION_OK) (Required is at least
version "3.2.90")
Call Stack (most recent call first):
/usr/share/cmake-4.3/Modules/FindPackageHandleStandardArgs.cmake:654
(_FPHSA_FAILURE_MESSAGE)
cmake/modules/FindEigen3.cmake:97 (find_package_handle_standard_args)
CMakeLists.txt:279 (find_package)
- -- Configuring incomplete, errors occurred!
cd obj-x86_64-linux-gnu && tail -v -n \+0 CMakeCache.txt
===========================================
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.
Thanks,
Anton
