distcc 2.1 for Mac could be downloaded from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. The software lies within Internet & Network Tools, more precisely Network tools. We recommend checking the downloaded files with any free antivirus.
From the developer:
distcc is a program to distribute builds of C, C++, Objective C or Objective C++ code across several machines on a network. distcc should always generate the same results as a local build, is simple to install and use, and is often two or more times faster than a local compile.
distcc does not require all machines to share a filesystem, have synchronized clocks, or to have the same libraries or header files installed.
You may want to check out more Mac applications, such as attach, which might be related to distcc.
