Package: libeigen3-dev
Version: 3.1.0-1
Severity: normal
Tags: patch
Dear Maintainer,
the bug can be demonstrated using Hauke's example from
http://forum.kde.nl/viewtopic.php?f=74&t=98871 (see enclosed file). The call to
Spline2d::derivative<1> is an extension of Hauke's example inserted
by me. This call makes this example fail to compile:
---8<-----8<-----8<-----8<-----8<-----8<-----8<-----8<-----8<-----8<----

---8<-----8<-----8<-----8<-----8<-----8<-----8<-----8<-----8<-----8<----
This bug can be fixed by changing in
/usr/include/eigen3/unsupported/Eigen/src/Splines/SplineFwd.h the
DerivativeType from ColMajor to RowMajor (see enclosed patch for details).
With this change everything compiles fine:

fixed 736985 3.2.0-1
thanks
Hi Philipp,
thanks for your bug-report. Upstream has fixed this issue in 3.2.0 release [1],
which is available in Debian Jessie. Thus I am closing the bug.
I have backported eigen 3.2.0 for Debian Wheezy, so it should probably
be available there soon [2].

Cheers,
Anton
