Eigen3 not in official repository

Hi,

This is probably not the best place to ask, but I can't find anything better.

Today I installed eigen by doing "pacman -S eigen". It pulled in "eigen2", which whole-heartedly surprised me. Version 3 has been out since March 2011.

I even found "eigen3" in the AUR, but seriously, why is Arch holding on to an older version in the official repo? For 3 years?

Thanks for any information.

Re: Eigen3 not in official repository

If I had to guess, I would say that that is the version needed for the packages that depend on it since there's an API change.

If no packages in the repos need version 3 and none of the devs/TUs have any interest in it, nobody's going to bother putting version 3 into the main repos.

I can see why you would want this, I guess you need all the mathematics help you can get? Less than 2 years != 3 years.

You're hilarious.

Still, I find this baffling. Especially the fact that both packages (eigen2 and eigen3) are version-numbered, install into a "/usr/include/eigenN" prefix, and the fact that the Eigen3 package has 100 votes.

Re: Eigen3 not in official repository

But if none of the devs or TUs use it or care about it, why would they maintain it? That's exactly what the AUR is for.
