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
spectra FTBFS with libeigen3-dev 5.0.1. The full build log is available at:
https://debusine.debian.net/debian/developers-gladk-eigen3/artifact/3761837/
Here is the most probably relevant part of the failing build log:
