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
mrtrix3 FTBFS with libeigen3-dev 5.0.1. The full build log is available at:
https://debusine.debian.net/debian/developers-gladk-eigen3/artifact/3758084/
Here is the most probably relevant part of the failing build log:
===========================================
Checking for Eigen3 library:
ERROR: error compiling Eigen3 application!
MRtrix3 was unable to compile a test program involving Eigen3.
Set the EIGEN_CFLAGS environment variable to inform 'configure' of
the flags it must provide to the compiler in order to compile
programs that use Eigen3 functionality; this may include the path to
the Eigen3 include files, as well as any required flags.
For example:
$ export EIGEN_CFLAGS="-isystem /usr/include/eigen3"
$./configure
(amend with the actual path to the Eigen3 include files on your system)
make[1]: *** [debian/rules:36: override_dh_auto_configure] Error 1
make[1]: Leaving directory '/build/reproducible-path/mrtrix3-3.0.8'
make: *** [debian/rules:33: binary-arch] Error 2
dpkg-buildpackage: error: debian/rules binary-arch subprocess failed with exit
status 2
===========================================
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
