Missing functions or build issue

[RedyJack]

Build project that uses only this:

use opencv::prelude::*;
use opencv::core;
use opencv::objdetect;

pub fn detect_faces() {
    let face_cascade = objdetect::CascadeClassifier::new("models/haarcascade_frontalface_default.xml").unwrap();
}

results in a lot of missing functions build.log :

Are they really missing or there may be some other issue? In .../sys directory there are some similar functions to deal with vectors but not those exact. If they are missing is there a plan to add them? If not any directions on adding those?

That looks like another issue #479 which I was not able to reproduce until now, but based on the image from you other issue I can see the error now so expect a fix soon!

[twistedfall]

This should be fixed in 0.85.3
