GCC is a retargetable and highly optimizing implementation of ANSI C. It was written by Richard Stallman and a cast of thousands (well, scores) around the world. Although GCC was originally designed to be a Unix-based compiler, this version has been adapted to be a drop-in replacement for the standard MPW™ C compiler. This distribution includes GCC, a preprocessor CCCP (cpp), and the yacc-compatible parser generator Bison.
To use MPW™ GCC, you will need a 68020/030+68881 Macintosh™*, MPW™ 3.1 or higher, MPW™ C, and MPW™ Asm. Although you don't need the MPW™ C compiler proper, the MPW™ C interfaces and library files are required. To run the gCPlus script, you will also need C++ 3.1. Although GCC can run in 2Mb or less, we recommend 4Mb RAM. Minimum additional disk space is 600K or so, but there will need to be some additional space for intermediate files. It would be ludicrous to run GCC from floppies.
(*See the document ":Documents:Hacking GCC" for some ideas about what to do if you have some other kind of Macintosh.)
(At the moment, GCC is INCOMPATIBLE with MPW™ 3.2 includes and library files, in particular the parameter pragmas. However, if you keep your 3.1 includes and libraries and put them in your paths, you can still use the rest of 3.2. This isn't great, but GCC isn't going to understand parameter pragmas anytime soon and MPW™ 3.2 includes/libraries REQUIRE that they be interpreted correctly.)
For details of installing GCC into your environment, see ":Documents:Installing GCC".
Once you've installed GCC, ":Documents:Using GCC" tells how to use GCC with MPW™. The file ":Documents:BUGS" briefly describes some known problems.
If you need help beyond what is provided in the Documents folder, we have established some e-mail addresses that will forward to support people:
AppleLink: MPWGCC
Internet: mpwgcc@apple.com
If neither of these are available to you, you may try to contact me directly. I can be reached at

and will be happy to help out where possible, and as time permits (this is not my main job!).
Finally, I would like to thank Wayne Loofbourrow, Mark Hennecke, Jim Murphy, Scott Douglass, Paul Snively, Larry Rosenstein and the other Appleites who have helped out with MPW™ GCC in one way or another, also Waldemar Horwat for finding lots of bugs. Jeff Holcomb deserves a special thanx for seemingly interminable testing and bug tracing, as well as designing the Commando interfaces. His efforts have been invaluable.

This is not an official product of Apple Computer! MPW™ GCC was developed to support Advanced Technology Group research efforts, and was deemed sufficiently useful to be made available to a wider audience. If you use this compiler, you should be prepared to support it yourself (full sources are included). Here is the proper legal wording, also see the file ":Documents:COPYING"
