Linux ARM64 (Native bindings for Linux ARM64) about opencvsharp HOT 6 OPEN

Thumbs up for ARM64 NuGet package for Raspberry Pi!

from opencvsharp.

Did you build it yourself or do you want me to post the one I built?

No, I didn't build it myself, I yust wanna see it build as NuGet package so that can be easily included for linux-arm64 Raspberry Pi projects.

Can you please post the one you built?

Here you go

Thanks for the library. Unfortunately it is dynamic linked unlike the static linked library in the nuget package OpenCvSharp4.runtime.linux-arm.

I built the OpenCV 4.9.0 binaries which took half a day on my Raspberry Pi 4. After that ldd /libOpenCvSharpExtern.so still displays a missing reference:

/lib/aarch64-linux-gnu/libstdc++.so.6: version 'GLIBCXX_3.4.32' not found

Running strings /lib/aarch64-linux-gnu/libstdc++.so.6 | grep GLIBCXX prints

...
GLIBCXX_3.4.27
GLIBCXX_3.4.28
GLIBCXX_3.4.29
GLIBCXX_3.4.30

So I'm trying to update libstdc++.so.6 which apparently is part of GCC. After building the GCC 13.2 binaries for a couple of hours it stopped with an error about an symbol lookup error: /lib/aarch64-linux-gnu/libicuuc.so.72: undefined symbol: _ZSt15__once_callable, version GLIBCXX_3.4.11.

During all the building I rewrote the C# app in Python, which is much easier to run on Linux. I really like C# and .NET, but things like that are just a hassle I don't need.
