FWIW, 'Eigen::AmbiVector<_Scalar>::nonZeros() const' was eventually changed to return int, among other (possibly unrelated) changes: https://bitbucket.org/eigen/eigen/commits/a99c2fa786e791e9ad1ef23b247e71ebd3367164
Turns out eigen2 was deprecated by upstream quite awhile ago, and nothing in fedora still depends on it. I'm leaning towards retirement
(In reply to Rex Dieter from comment #5) > I'm leaning towards retirement IIRC the KDE4 kdeplasma-addons BR'd it, but I guess anyone with that in a copr will just have to maintain eigen2 themselves (or drop whichever feature required it).
This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component.
Went the orphan route, to make it easier for someone else to pick it up
