# GNU tools and their documentation

Cygnus’s GNUPro Toolkit, which includes the GCC and G++ compilers and the GDB debugger, is needed to build eCos applications. It is bundled with the CDROM distribution of the eCos Developer’s Kit, and is also available on the Cygnus Sourceware site.

Online HTML versions of the full GNUPro documentation are provided, as well as a specific reference guide for your hardware architecture. The full GNUPro documentation can also be found on the web at http://www.cygnus.com/pubs/gnupro/.

> Note: The Linux synthetic i386 target is an exception, as there is (currently) no GNUPro manual. However, the GNUPro source archive contains documentation for the tools. This documentation is usually also included as part of a default RedHat Linux installation, accessible with the info program.

The version of GNUPro bundled with eCos contains some new features which are not yet in the standard release, including selective linking of functions and data and constructor priority ordering. These features are described in the GNUPro reference for each architecture.
