About

HWSD is a cross-platform library, designed to run on any modern operating system, including all Unix variants and the Windows operating system. Zeroconf support in Lunchbox is required for the DNS_SD module and applications.

HWSD uses CMake and Buildyard to create a platform-specific build environment. The following platforms and build environments are tested:

• Linux: Ubuntu 12.04, 12.10, 13.04, RHEL 6.3 (Makefile, i386, x64)
• Windows: 7 (Visual Studio 2008, i386, x64)
• Mac OS X: 10.8 (Makefile, i386, x64)
