In software development, distcc is a tool for speeding up compilation of source code by using distributed computing over a computer network. With the right configuration, distcc can dramatically reduce a project's compilation time.
It is designed to work with the C programming language (and its derivatives like [[C++]] and Objective-C) and to use GCC as its backend , though it provides varying degrees of compatibility with the [[Intel C++ Compiler]] and Sun Microsystems' compiler.[1] Distributed under the terms of the GNU General Public License, distcc is free software.
Design
The intention is to speed up compilation by utilising unused processing power on other computers. A machine with distcc installed can send code to be compiled across the network to a computer which has the distccd daemon and a compatible compiler installed.
distcc works as an agent for the compiler. A distcc daemon has to run on each of the participating machines. The originating machine invokes a preprocessor to handle header files, preprocessing directives (such as #ifdef) and the source files and sends the preprocessed source to other machines over the network via TCP either unencrypted or using SSH. Remote machines compile those source files without any local dependencies (such as libraries, header files or macro definitions) to object files and send them back to the originator for further compilation.

distcc is an option for distributed builds in Apple's Xcode development suite.
