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
fcl FTBFS with libeigen3-dev 5.0.1. The full build log is available at:
https://debusine.debian.net/debian/developers-gladk-eigen3/artifact/3755617/raw/fcl_0.7.0-3_amd64-2026-05-08T08:27:49Z.build

===========================================
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,
