OpenCvSharp Native Runtime Package

This is an internal implementation package for OpenCvSharp. It provides the native OpenCV shared library (OpenCvSharpExtern) for a specific platform.

In most cases you do not need to reference this package directly. Use one of the all-in-one packages instead:

  • Windows: OpenCvSharp4.Windows or OpenCvSharp4.Windows.Slim
  • Linux: OpenCvSharp4 + OpenCvSharp4.official.runtime.linux-x64

The Linux linux-x64 packages are built on manylinux_2_28 (glibc 2.28) and work on Ubuntu 20.04+, Debian 10+, RHEL/AlmaLinux 8+, and other Linux distributions. The full (non-slim) package includes FFmpeg (LGPL v2.1) and Tesseract statically linked.

Linux highgui dependency: The full linux-x64 package uses GTK3 for highgui (Cv2.ImShow, Cv2.WaitKey, etc.). GTK3 is pre-installed on standard Ubuntu/Debian/RHEL environments. In minimal or container environments where it is absent, install it manually:

  • Ubuntu/Debian: apt-get install libgtk-3-0
  • RHEL/AlmaLinux: dnf install gtk3

For headless servers or minimal containers, use the slim package (OpenCvSharp4.official.runtime.linux-x64.slim) instead, which disables highgui and has no GUI dependencies.
