This has also been filed in Ubuntu and upstream:
https://bugs.launchpad.net/ubuntu/+source/avogadro/+bug/1640171
https://sourceforge.net/p/avogadro/bugs/783/
It seems to be an issue with out eigen3 patch, there's since been a
different commit upstream, and Khanh-Dang Nguyen Thu Lam confirmed this:
22:39 <zooe> compilation just done
22:39 <zooe> it works :)
22:40 <zooe> i did: "apt-get source avogadro", replaced
debian/patches/eigen3.patch by 43af3c117b0b3220b15c2fe2895b94bbd83d3a60,
then compiled it
https://github.com/cryos/avogadro/commit/43af3c117b0b3220b15c2fe2895b94bbd83d3a60
is the relevant changeset.
