The GNU toolchain is a blanket term given to the programming tools produced by the GNU project. These projects form an integrated system that is used for programming both applications and operating systems.

It is a vital component in Linux kernel development, BSD development and a standard tool when developing software for embedded systems. Parts of the toolchain are also widely used in the Solaris Operating Environment (which, in the opinion of many, needs the GNU tools for reasonable usability) and Microsoft Windows programming with Cygwin.
