23 /* Capsule summary of different preprocessor flags:
|
|
|
24
|
|
|
25 1. Keep in mind that there are two possible OS environments we are dealing
|
|
|
26 with -- Cygwin and Native Windows. Cygwin provides a POSIX emulation
|
|
|
27 layer on top of MS Windows -- in particular, providing the file-system,
|
|
|
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).
|
|
428
|
56
|
|
442
|
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
|
|
|
