Libudev-stub is a shim library for libudev, created primarily for the Windows Subsystem for Linux WSL. Theoretically it could be useful for other Linux-ish systems that lack udev support. Udev is part of systemd. It provides a well-known interface for device events (such as hot plugging of usb dongles and cameras) for many Linux distributions like Ubuntu. Unfortunately, WSL currently lacks much of the functionality required to support udev; at least as of Windows Insider build 16257.
libudev-stub implements a subset of the libudev interface and does not actually communicate with the kernel. The theory of operation is pretty straightforward. When an application uses libudev to ask for a list of devices, the stub library says there aren't any devices worth mentioning. When an application asks to monitor for device events, the library obliges, and then never raises any event notifications. The code is structured in a way that a static device list could be faked, but it does not do so as of right now.
bash
Then,
wget https://github.com/suhan-paradkar/tewmux-disabled/releases/download/udev-stub/libudev-stub_228_$(dpkg --print-architecture).deb
dpkg -i libudev-stub_228_aarch64.debThere is also an environment variable to turn the stub library into a passthrough proxy for the real libudev.so.1. It is useful to see where applications fail when using the libudev interface. Enable it with:
export LIBUDEV_STUB_PASSTHROUGH=$PREFIX/lib/libudev.so.1.6.4
