Comment 1 Ionen Wolkens gentoo-dev 2021-03-17 07:58:42 UTC 
Hm, obviously something to do with opencv but can't reproduce.
Comment 2 nE0sIghT 2021-03-17 08:17:25 UTC 
In case it will help: emerge --info media-libs/opencv

media-libs/opencv-4.5.0::gentoo was built with the following:

Comment 3 Ionen Wolkens gentoo-dev 2021-03-17 08:50:30 UTC 
(In reply to nE0sIghT from comment #2)
> In case it will help: emerge --info media-libs/opencv
It did, thanks. Re-enable the default features2d on opencv.

I find it kind of curious this flag exists rather than being always-enabled.
Comment 4 nE0sIghT 2021-03-17 10:22:29 UTC 
I'm really confused why it is not enabled for me:

Comment 5 Stephen Cavilia 2021-11-23 22:15:36 UTC 
Seeing the same failure in frei0r-plugins 1.7.0, but features2d was already enabled on opencv.

Message from opencv configuration about the objdetect module was:

-- Module opencv_objdetect disabled because opencv_dnn dependency can't be resolved!

Needed to also enable contribdnn for the objdetect module to build.
