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   (It looks like, nowadays, if HAVE_X11 is set, HAVE_X_WINDOWS must
  26    be, and vice versa.  At least, this is true for configure, and
  27    msdos; not sure about nt.)
  28 USE_LUCID       Use the Lucid toolkit for menus&scrollbars.  Requires HAVE_X11.
  29 USE_MOTIF       Use the Motif toolkit for menus&scrollbars.  Requires HAVE_X11.
  30 USE_GTK         Use the Gtk   toolkit for menus&scrollbars.  Requires HAVE_X11.
  31
  32 ** Frame types **
  33
  34 FRAME_TERMCAP_P A tty (character terminal) frame.
  35 FRAME_X_P       A frame on X Window system.
  36 FRAME_MSDOS_P   An MS-DOS frame (used only by the DOS port).
  37 FRAME_W32_P     A frame using native MS-Windows GUI.
  38 FRAME_WINDOW_P  A GUI frame (like X, w32, etc.)
  39
  40 ** Support for accessing other processes on the system **
  41
  42 HAVE_PROCFS     The /proc filesystem is supported.
  43
  44 ** Compile-time options **
  45
  46 REL_ALLOC       Compile in the relocatable memory allocator ralloc.c.
  47 SYSTEM_MALLOC   Use the system library's malloc.
  48 subprocesses    System can use subprocesses (for M-x shell for example).  Defined by default, only MSDOS undefines it.
  49 DEBUG_LISP_OBJECT_TYPE Define it in lisp.h enable compile time checks on Lisp_Object use.
  50
  51 ** System specific macros, described in detail in src/s/template.h
  52 CLASH_DETECTION
  53 COFF
  54 FIRST_PTY_LETTER
  55 HAVE_PTYS
  56 INTERRUPT_INPUT
  57 NARROWPROTO
  58 SEPCHAR
  59 SYSTEM_TYPE
  60
  61 ** Misc macros
  62 USER_FULL_NAME   If defined, overrides the default pw->pw_gecos for getting at the full user name.  Only MSDOS overrides the default.
  63
  64 ** Replace, the definition is trivial: SWITCH_ENUM_CAST
  65
  66 ** Defines from 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/s/*.h.
