23 #ifndef WINDOWSNT 23 /* Capsule summary of different preprocessor flags:
24 #define WINDOWSNT 24
25 #endif 25 1. Keep in mind that there are two possible OS environments we are dealing
26 26 with -- Cygwin and Native Windows. Cygwin provides a POSIX emulation
27 #ifndef DOS_NT 27 layer on top of MS Windows -- in particular, providing the file-system,
28 #define DOS_NT /* MSDOS or WINDOWSNT */ 28 process, tty, and signal semantics that are part of a modern, standard
29 Unix operating system. MS Windows also provides these services, but
30 through their own API, called Win32. When compiling in a Cygwin
31 environment, the Win32 API's are also available, and in fact are used
32 to do native GUI programming.
33
34 2. There are two windowing environments we can target XEmacs for when
35 running under MS Windows -- Windows native, and X. (It may seem strange
36 to write an X application under Windows, but there are in fact many X
37 servers out there running on Windows, and as far as I know there is no
38 real (or at least, that works well) networking Window-system extension
39 under MS Windows. Furthermore, if you're porting a Unix application to
40 Windows and use Cygwin to assist you, it might seem natural to use an
41 X server to avoid having to port all the code to Windows.) For XEmacs,
42 there are various reasons people could come up with for why we would
43 want to keep maintaining X Windows under MS Windows support.
44
45 That gives us four possible build environments. I (Ben) build
46 regularly on fully-native-everything, Andy builds on Cygwin + MS
47 Windows + X Windows for windowing.
48
49 The build flags used for these divisions are:
50
51 CYGWIN -- for Cygwin-only stuff.
52 WIN32_NATIVE -- Win32 native OS-level stuff (files, process, etc.).
53 HAVE_X_WINDOWS -- for X Windows (regardless of whether under MS Win)
54 HAVE_MS_WINDOWS -- MS Windows native windowing system (anything related to
55 the appearance of the graphical screen).
56
57 Finally, there's also the MINGW build environment, which uses GCC
58 \(similar to Cygwin), but native MS Windows libraries rather than a
59 POSIX emulation layer (the Cygwin approach). This environment defines
60 WIN32_NATIVE, but also defines MINGW, which is used mostly because
61 uses its own include files (related to Cygwin), which have a few
62 things messed up.
63
64
65 Formerly, we had a whole host of flags. Here's the conversion, for porting
66 code from GNU Emacs and such:
67
68
69 WINDOWSNT -> WIN32_NATIVE
70 WIN32 -> WIN32_NATIVE
71 _WIN32 -> WIN32_NATIVE
72 HAVE_WIN32 -> WIN32_NATIVE
73 DOS_NT -> WIN32_NATIVE
74 HAVE_NTGUI -> WIN32_NATIVE, unless it ends up already bracketed by this
75 HAVE_FACES -> always true
76 MSDOS -> determine whether this code is really specific to MS-DOS (and not
77 Windows -- e.g. DJGPP code); if so, delete the code; otherwise,
78 convert to WIN32_NATIVE (we do not support MS-DOS w/DOS Extender
79 under XEmacs)
80
81 __CYGWIN__ -> CYGWIN
82 __CYGWIN32__ -> CYGWIN
83 __MINGW32__ -> MINGW
