  13    provided also that they carry prominent notices stating who last
  14    changed them.
  15
  16 You can use either Metrowerks CodeWarrior Pro 5 or 6 or MPW-GM
  17 (Aug. 2000) to build Emacs.  MPW-GM can be downloaded free of charge
  18 from Apple at
  19
  20   http://developer.apple.com/tools/mpw-tools/
  21
  22 You will need MPW-GM to build the make-docfile utility and to generate
  23 the doc string file DOC.
  24
  25 To decompress files, you can use MacGzip from
  26
  27   http://persephone.cps.unizar.es/~spd/gzip
  28
  29 and to untar them, you can use tar 4.0 from
  30
  31   http://hyperarchive.lcs.mit.edu/HyperArchive/Archive/cmp/tar-40b.hqx
  32
  33 (Optional) If you wish to fetch files from the Emacs CVS repository
  34 directly to your Mac, you can use the CVS client MacCVS, which can be
  35 downloaded from
  36
  37   http://www.wincvs.org/
  38
  39 (Optional) A subset of the fonts from the GNU intlfonts-1.2
  40 distribution converted to NFNT format can be obtained from
  41
  42   ftp://mac-emacs.sourceforge.net/pub/mac-emacs/GNU-fonts.smi.bin

  44 * BUILDING EMACS
  45
  46 To build Emacs in the MPW Shell, simply set the directory to
  47 ...:emacs:mac: and build the target Emacs of the make file
  48 makefile.mpw.  I.e., execute the commands
  49
  50   make Emacs -f makefile.MPW > Emacs.MakeScript
  51   Emacs.MakeScript
  52
  53 To build Emacs using CodeWarrior, start up the CodeWarrior IDE, choose
  54 File->Import Project...  and select the file cw5-mcp.xml or
  55 cw6-mcp.xml, depending on which verison of CodeWarrior used.  When
  56 prompted to save the project, navigate to same directory as the file
  57 cw[56]-mcp.xml, name it emacs-cw5.mcp or emacs-cw6.mcp, and save it
  58 there.  Then choose Project->Make.  Note that this does not build the
  59 DOC file.  To do so, use MPW and build the target "Doc" in
  60 makefile.MPW.
  61
  62 Once built, the Emacs application (Emacs CW or Emacs MPW) can be
  63 launched where it is created.
  64
  65 To build an optimized version of Emacs in CodeWarrior, change the
  66 value in the Emacs Settings->Code Generation->Global Optimization
  67 dialog.  To build a version for profiling, check the Profiler
  68 Information box in the Emacs Settings->Code Generation->PPC Processor
  69 dialog and include the Profiler PPC.Lib library.
  70
  71 To build optimized or debugging version of Emacs in MPW, follow the
  72 comment in makefile.MPW to enable the -opt speed or -sym on option
  73 (see note below).
  74
  75 The Mac version requires compiled Lisp files to be present in the lisp
  76 directory to run properly.  It is cumbersome to bootstrap from only
  77 the Lisp source files.  One way of getting the compiled Lisp files is
  78 to build Emacs once on, say, a Unix system and transfer that directory
  79 to the Mac.  Note that linefeed conversion must be disabled when
  80 transferring compiled Lisp files.
  81
  82 An alternative is to unzip and untar the archive lisp-elc.tgz.  An
  83 older version of frame.elc in the archive may cause a problem when the
  84 Mac version starts up.  If this is the case, simply remove or rename
  85 that file.  Then once Emacs runs, you can invoke
  86 byte-recompile-directory on the lisp directory to byte-compile all
  87 out-of-date Lisp files.
  88
  89 You may also need to run update-autoloads-from-directories on the lisp
  90 directory to bring loaddefs.el up-to-date.
  91
  92 * NOTES
  93
  94 Emacs should build and run on a PowerMac running Mac OS 8.1 - 9.0.
  95
  96 You will need around 100 MB of disk space for the source files and
  97 intermediate files.
  98
  99 It will not run on machines with more than 256 MB of physical or
 100 virtual memory.
 101
 102 Currently there is no support for building the LEIM directory on the
 103 Mac.  However, it can be built on another platform and transferred to
 104 the Mac.
 105
 106 When Emacs is built with "-opt speed" enabled in makefile.MPW,
 107 optimization causes the functions reset_buffer_local_variables in
 108 buffer.c and syms_of_lread in lread.c to crash.  Avoid this by
 109 enclosing them in the following pragmas.
 110
 111   #pragma options opt off
 112
 113   <function definition...>
 114
 115   #pragma options opt reset
 116
 117 To use the same icon as when Emacs is built on Windows NT, define
 118 GNU_ICON in mac/src/Emacs.r.
