Is there a rough date for Avogadro 2? My concern is that it is still hard to find Eigen 3 on some distros. Even on arch, which stays fairly bleeding edge, it is only available from a third party repo. I have a feeling it may be more difficult for enterprise distros. But then, is eigen really even a dependence for binary distros? Since everything is templated and inline, we may only need to require package builders to install Eigen 3. I'm not sure how acceptable this would be to packagers. Dave ------------------------------------------------------------------------------ Keep Your Developer Skills Current with LearnDevNow!
