  1. Operating system
    Ubuntu Gnome X11
  2. The way you installed OpenCV: package, official binary distribution, manual compilation, etc.
    OpenCV installed via cargo package
  3. OpenCV version
    opencv = "0.94.2"
  4. rustc version (rustc --version)
    rustc 1.82.0 (2024-10-15)
  5. Attach the full output of the following command from your project directory: shell script RUST_BACKTRACE=full cargo build -vv
    cargo run RUST_BACKTRACE=full cargo build -vv
    target/debug/opencvx: symbol lookup error: /snap/core20/current/lib/x86_64-linux-gnu/libpthread.so.0: undefined symbol: __libc_pthread_init, version GLIBC_PRIVATE

My code:

use opencv::prelude::*;
use opencv::{highgui, videoio, Result};

fn main() -> Result<()> {
    
    let window = "video capture";
    highgui::named_window(window, highgui::WINDOW_AUTOSIZE)?;

    let mut cam = videoio::VideoCapture::new(0, videoio::CAP_ANY)?;
    let opened = videoio::VideoCapture::is_opened(&cam)?;
    if !opened {
        panic!("Unable to open default camera!");
    }

    loop {
        let mut frame = Mat::default();
        cam.read(&mut frame)?;
        if frame.size()?.width > 0 {
            highgui::imshow(window, &frame)?;
        }
        let key = highgui::wait_key(10)?;
        if key > 0 && key != 255 {
            break;
        }
    }

    // Очистка
    highgui::destroy_all_windows()?;
    Ok(())
}

The error seems to be unrelated to the crate on the first glance, some kind of linking inconsistency on your system. But to be extra sure please provide the full output of cargo build -vv after running cargo clean.

Yes, this problem was in something else. But problem in OpenCV too exists. And Now, I have installed opencv 4.9.0 instead of 4.7.0. And I have another problem:

The crate supports whatever your system OpenCV installation supports, so it should be fine. The error indicates a problem linking with dnn module of OpenCV. Please do a cargo clean and then post a full output of cargo build -vv. The log will contain debug information that could help to debug the issue.

cargo build -vv 2>&1 | tee build_log.txt should work

I already see something weird though, you're saying you're using crate version 0.94, but in this last log snippet I can see references to opencv-0.91.3.

Yes, but with 0.94 I have this errors also

It looks like the linker is trying to link to a different OpenCV (not the one that was used for binding generation) which lacks the necessary DNN features. Maybe the 4.7.0 version that you used previously is still lingering?

I dont know how I can check it, but I have been removing opencv package lib dev before installing 4.9.0
