admin/CPP-DEFINES

   1 Here are some of the cpp macros used, together with some short explanation
   2 of their use.  Feel free to add more macros and more categories.
   3
   4 ** Distinguishing OSes **
   5
   6 CYGWIN          Compiling the Cygwin port.
   7 __CYGWIN__      Ditto
   8 MSDOS           Compiling the MS-DOS port.
   9 __MSDOS__       Ditto.
  10 __DJGPP_MINOR__ Minor version number of the DJGPP library; used only in msdos.c and dosfns.c.
  11 DOS_NT          Compiling for either the MS-DOS or native MS-Windows port.
  12 WINDOWSNT       Compiling the native MS-Windows (W32) port.
  13 __MINGW32__     Compiling the W32 port with the MinGW port of GCC.
  14 _MSC_VER        Compiling the W32 port with the Microsoft C compiler.
  15 DARWIN_OS       Compiling on Mac OS X or pure Darwin (and using s/darwin.h).
  16
  17 ** Distinguishing GUIs **
  18
  19 HAVE_NTGUI      Use the native W32 GUI for windows, frames, menus&scrollbars.
  20 HAVE_NS         Use the NeXT/OpenStep/Cocoa UI under Mac OS X or GNUstep.
  21 NS_IMPL_GNUSTEP Compile support for GNUstep implementation of NS GUI API.
  22 NS_IMPL_COCOA   Compile support for Cocoa (Apple) implementation of NS GUI API.
  23 HAVE_X11        Compile support for the X11 GUI.
  24 HAVE_X_WINDOWS  Compile support for X Window system
  25 X11             ??  Makefile.in suggests it's equivalent to HAVE_X11
  26 USE_LUCID       Use the Lucid toolkit for menus&scrollbars.  Requires HAVE_X11.
  27 USE_MOTIF       Use the Motif toolkit for menus&scrollbars.  Requires HAVE_X11.
  28 USE_GTK         Use the Gtk   toolkit for menus&scrollbars.  Requires HAVE_X11.
  29
  30 ** Frame types **
  31
  32 FRAME_TERMCAP_P A tty (character terminal) frame.
  33 FRAME_X_P       A frame on X Window system.
  34 FRAME_MSDOS_P   An MS-DOS frame (used only by the DOS port).
  35 FRAME_W32_P     A frame using native MS-Windows GUI.
  36 FRAME_WINDOW_P  A GUI frame (like X, w32, etc.)
  37
  38 ** Support for accessing other processes on the system **
  39
  40 HAVE_PROCFS     The /proc filesystem is supported.
  41
  42 ** Compile-time options **
  43
  44 REL_ALLOC       Compile in the relocatable memory allocator ralloc.c.
  45 SYSTEM_MALLOC   Use the system library's malloc.
  46 subprocesses    System can use subprocesses (for M-x shell for example).  Defined by default, only MSDOS undefines it.
  47 USE_LISP_UNION_TYPE Define it in lisp.h to make Lisp_Object be a union type instead of the default int.
  48
  49 ** System specific macros, decribed in detail in src/s/template.h
  50 BSTRING
  51 CLASH_DETECTION
  52 COFF
  53 FIRST_PTY_LETTER
  54 HAVE_PTYS
  55 HAVE_TERMIO
  56 HAVE_TERMIOS
  57 INTERRUPT_INPUT
  58 MAIL_USE_FLOCK
  59 NARROWPROTO
  60 NOMULTIPLEJOBS
  61 SEPCHAR
  62 SIGTYPE
  63 SYSTEM_TYPE
  64 USE_MMAP_FOR_BUFFERS
  65
  66 ** Machine specific macros, decribed in detail in src/m/template.h
  67 CANNOT_DUMP
  68 EXPLICIT_SIGN_EXTEND
  69 LOAD_AVE_CVT
  70 LOAD_AVE_TYPE
  71 NO_ARG_ARRAY
  72 NO_REMAP
  73 VIRT_ADDR_VARIES
  74 WORDS_BIG_ENDIAN
  75
  76 ** Misc macros
  77 USER_FULL_NAME   If defined, overrides the default pw->pw_gecos for getting at the full user name.  Only MSDOS overrides the default.
  78
  79 ** Replace, the definition is trivial: SWITCH_ENUM_CAST
  80
  81 ** Defines from src/m/*.h and src/s/*.h.  Some of these might not be used in the code anymore, so they can be removed.  The HAVE_* definitions are probably handled by autoconf, so it might be possible to just remove them from src/[sm]/*.h.
