You can use either Metrowerks CodeWarrior Pro 5 or 6 or MPW-GM (Aug. 2000) to build Emacs. MPW-GM can be downloaded free of charge from Apple at http://developer.apple.com/tools/mpw-tools/ You will need MPW-GM to build the make-docfile utility and to generate the doc string file DOC. To decompress files, you can use MacGzip from http://persephone.cps.unizar.es/~spd/gzip and to untar them, you can use tar 4.0 from http://hyperarchive.lcs.mit.edu/HyperArchive/Archive/cmp/tar-40b.hqx (Optional) If you wish to fetch files from the Emacs CVS repository directly to your Mac, you can use the CVS client MacCVS, which can be downloaded from http://www.wincvs.org/ (Optional) A subset of the fonts from the GNU intlfonts-1.2 distribution converted to NFNT format can be obtained from ftp://mac-emacs.sourceforge.net/pub/mac-emacs/GNU-fonts.smi.bin ### IMPORTANT ### If you use StuffIf Expander to decompress and untar the distribution, you *must* set the radio button in the Preferences->Cross Platform->Convert text files to Macintosh format to "Never". Otherwise the compiled Lisp files will be corrupted. * BUILDING EMACS To build Emacs in the MPW Shell, simply set the directory to ...:emacs:mac: and build the target Emacs of the make file makefile.mpw. I.e., execute the commands make Emacs -f makefile.MPW > Emacs.MakeScript Emacs.MakeScript To build Emacs using CodeWarrior, start up the CodeWarrior IDE, choose File->Import Project... and select the file cw5-mcp.xml or cw6-mcp.xml, depending on which verison of CodeWarrior used. When prompted to save the project, navigate to same directory as the file cw[56]-mcp.xml, name it emacs-cw5.mcp or emacs-cw6.mcp, and save it there. Then choose Project->Make. Note that this does not build the DOC file. To do so, use MPW and build the target "Doc" in makefile.MPW. Once built, the Emacs application (Emacs CW or Emacs MPW) can be launched where it is created. To build an optimized version of Emacs in CodeWarrior, change the value in the Emacs Settings->Code Generation->Global Optimization dialog. To build a version for profiling, check the Profiler Information box in the Emacs Settings->Code Generation->PPC Processor dialog and include the Profiler PPC.Lib library. To build optimized or debugging version of Emacs in MPW, follow the comment in makefile.MPW to enable the -opt speed or -sym on option (see note below). * NOTES Emacs should build and run on a PowerMac running Mac OS 8.1 - 9.0. You will need around 100 MB of disk space for the source files and intermediate files. It will not run on machines with more than 256 MB of physical or virtual memory. Currently there is no support for building the LEIM directory on the Mac. However, it can be built on another platform and transferred to the Mac. When Emacs is built with "-opt speed" enabled in makefile.MPW, optimization causes the functions reset_buffer_local_variables in buffer.c, syms_of_lread in lread.c, and x_draw_hollow_cursor in macterm.c to crash. Avoid this by enclosing them in the following pragmas. #pragma options opt off <function definition...> #pragma options opt reset To use the same icon as when Emacs is built on Windows NT, define GNU_ICON in mac/src/Emacs.r.
