What is the Unix Compatibility Subsystem?

The Unix Compatibility Subsystem is built around a component known as kLIBC, which is itself a project hosted at OS/2 Netlabs. The subsystem consists of a collection of applications generally ported from Linux, and when built from source using the gcc compiler, become native OS/2 applications.

This subsystem brings a whole new world of modern, maintained applications to the OS/2 platform.

While this subsystem is installed as part of ArcaOS, earlier OS/2 Warp 4 distributions may take advantage of this environment and run these applications as well. All that is required to get started is to download and install Arca Noae Package Manager (ANPM), available from this page.

See this wiki page for more information about the Unix Compatibility Subsystem.
