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
g2o FTBFS with libeigen3-dev 5.0.1. The full build log is available at:
https://debusine.debian.net/debian/developers-gladk-eigen3/artifact/3755814/
Here is the most probably relevant part of the failing build log:
===========================================
The following information may help to resolve the situation:
The following packages have unmet dependencies:
sbuild-build-depends-main-dummy : Depends: debhelper (>= 11) but it is not
going to be installed
Depends: cmake but it is not going to be
installed
Depends: libopenblas-dev but it is not going
to be installed
Depends: libsuitesparse-dev but it is not
going to be installed
Depends: libopengl-dev but it is not going
to be installed
Depends: libqglviewer-headers but it is not
going to be installed
Depends: libeigen3-dev but it is not going
to be installed
Depends: libglut-dev but it is not going to
be installed
Depends: libtbb-dev but it is not going to
be installed
Depends: libmetis-dev but it is not going to
be installed
Depends: libceres-dev but it is not going to
be installed
Depends: libgmock-dev but it is not going to
be installed
E: Unable to satisfy dependencies. Reached two conflicting assignments:
1. libceres-dev:amd64 is selected for install because:
1. sbuild-build-depends-main-dummy:amd64=0.invalid.0 is selected for
install
2. sbuild-build-depends-main-dummy:amd64 Depends libceres-dev
2. libceres-dev:amd64 Depends libeigen3-dev (< 3.4.1)
but none of the choices are installable:
- libeigen3-dev:amd64=3.4.0-5 is not selected for install
apt-get failed.
E: Package installation failed
===========================================
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
