Can you please try setting HOST_TRIPPLE=x86_64-unknown-linux-musl environment variable for the build? It should work this around.

Can you please try switching from the crates.io release to the rel branch from this repo and try again to see if the issue is fixed?

I see, can you please try building with HOST_TRIPLE=x86_64-unknown-linux-gnu instead of "x86_64-unknown-linux-musl"?

build with HOST_TRIPLE=x86_64-unknown-linux-gnu cargo build --release --target x86_64-unknown-linux-gnu -vv output.log

Please leave the --target as you need it, you had initially "x86_64-unknown-linux-musl", only the HOST_TRIPLE should be set to "x86_64-unknown-linux-gnu"

output.log

The last error line is error occurred: Failed to find tool. Ismusl-g++installed?, is your system configured correctly to build binaries linked with musl?

Sorry，I can't reproduce on ubuntu(this is my docker container and it has been destroyed)

Now try in Alpine3.17(docker) install package

apk add --no-cache tzdata cmake make gcc g++ linux-headers clang-static curl llvm15-dev  git ncurses-static 
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- --default-toolchain nightly --profile minimal --target x86_64-unknown-linux-musl -y

build opencv: build_opencv.txt

code:

use opencv::core;
use opencv::highgui;
use opencv::imgcodecs;
use opencv::imgproc;
use opencv::prelude::*;
fn main() {
}

command:

HOST_TRIPLE=x86_64-unknown-linux-musl cargo build --release --target x86_64-unknown-linux-musl -vv > stdout.log 2>stderr.log

when in my project Cargo.toml opencv = { git = "https://github.com/twistedfall/opencv-rust", version = "0.81.3" } compile log: stderr.log stdout.log

after that : git clone https://github.com/twistedfall/opencv-rust/ add static like this: clang = { version = "2", features = ["clang_6_0", "static"] } change my project Cargo.toml : opencv = { path = "../opencv-rust" } compile log: stderr.log stdout.log and a file in opencv-rust with name core.64006 : core.64006.log

I had the same problem (build fails on ubuntu 22.04).

I Installed libstdc++-12-dev with sudo apt and it was solved.

You're the best
