Package version inconsistent with Eigen's

[TANGUY Arnaud]

There seems to be a mismatch between the advertised Ubuntu Trusty's libeigen-dev package version (3.2.0-8)and the actual eigen code it's based on (3.1.0).

In Ubuntu Trusty, the Eigen package is described as follow:
Package: libeigen3-dev
Priority: extra
Section: universe/libdevel
Installed-Size: 3729
Maintainer: Ubuntu Developers <email address hidden>
Original-Maintainer: Debian Science Maintainers <email address hidden>
Architecture: all
Source: eigen3
Version: 3.2.0-8
Provides: libeigen2-dev
Depends: pkg-config
Suggests: libeigen3-doc, libmrpt-dev
Filename: pool/universe/e/eigen3/libeigen3-dev_3.2.0-8_all.deb

So, according to this, the package provides Eigen 3.2.0
However, inspecting the installed files, it seems that it is in fact based on Eigen 3.1.0

I noticed this while trying to use the LevenbergMarquardt unsupported Eigen API:
- Code for Eigen 3.1 (corresponding exactly to the code in the package): https://goo.gl/J4kFeq

- Code for 3.2: https://goo.gl/hNkaeY

This is problematic, as there is a significant API change between Eigen 3.1 and 3.2 for the LevenbergMarquart algorithm.

Could you have a look at what's going on there?

Best regards,

Hi Arnaud

> - Code for 3.2: https://goo.gl/hNkaeY
This is the head of the 3.2 branch, currently at 3.2.10.

The version in Trusty is based on 3.2.0. It appears that the API changed within the 3.2 branch.
