15 #define _WX_PLATFORM_H_
18 first define Windows symbols if they're not defined on the command line: we
19 can autodetect everything we need if _WIN32 is defined
21 #if defined(_WIN32) || defined(WIN32) || defined(__NT__) || defined(__WXWINCE__)
30 /* Win95 means Win95-style UI, i.e. Win9x/NT 4+ */
31 #if !defined(__WIN95__) && defined(WINVER) && (WINVER >= 0x0400)
36 #if defined(__WXMSW__) || defined(__WIN32__)
37 #if !defined(__WINDOWS__)
54 #if defined(TWIN32) && !defined(__TWIN32__)
59 Include wx/setup.h for the Unix platform defines generated by configure and
60 the library compilation options
64 /* check the consistency of the settings in setup.h */
65 #include "wx/chkconf.h"
68 old C++ headers (like <iostream.h>) declare classes in the global namespace
69 while the new, standard ones (like <iostream>) do it in std:: namespace
71 using this macro allows constuctions like "wxSTD iostream" to work in
81 OS: first of all, test for MS-DOS platform. We must do this before testing
82 for Unix, because DJGPP compiler defines __unix__ under MS-DOS
84 #if defined(__GO32__) || defined(__DJGPP__) || defined(__DOS__)
88 /* size_t is the same as unsigned int for Watcom 11 compiler, */
89 /* so define it if it hadn't been done by configure yet */

92 #define wxSIZE_T_IS_UINT
95 #define wxSIZE_T_IS_ULONG
100 OS: then test for generic Unix defines, then for particular flavours and
101 finally for Unix-like systems

110 /* Helps SGI compilation, apparently */
113 #define __need_wchar_t
116 Note I use the term __SGI_CC__ for both cc and CC, its not a good
117 idea to mix gcc and cc/CC, the name mangling is different
120 #endif /* gcc/!gcc */
123 #if defined(sun) || defined(__SUN__)

157 These defines are needed when compiling using Project Builder
158 with a non generated setup0.h

177 Some code has been added to workaround defects(?) in the
178 bundled gcc compiler. These corrections are identified by
179 __DARWIN__ for Darwin related corrections (wxMac, wxMotif)
181 #elif defined(__OS2__)

195 #define LINKAGEMODE _Optlink
197 #define wxSIZE_T_IS_UINT
204 /* to be changed for Win64! */
210 define another standard symbol for Microsoft Visual C++: the standard
211 one (_MSC_VER) is also defined by Metrowerks compiler
213 #if defined(_MSC_VER) && !defined(__MWERKS__)
214 #define __VISUALC__ _MSC_VER

224 #if !defined(wxSIZE_T_IS_UINT) && !defined(wxSIZE_T_IS_ULONG)
225 #define wxSIZE_T_IS_UINT
230 if we're on a Unix system but didn't use configure (so that setup.h didn't
231 define __UNIX__), do define __UNIX__ now
233 #if !defined(__UNIX__) && defined(__UNIX_LIKE__)
237 #if defined(__HPUX__) && !defined(__WXGTK__)
240 #endif /* __WXMOTIF__ */
243 #if defined(__WXMOTIF__) || defined(__WXX11__)
248 This macro can be used to test the gcc version and can be used like this:
250 #if wxCHECK_GCC_VERSION(3, 1)
251 ... we have gcc 3.1 or later ...
253 ... no gcc at all or gcc < 3.1 ...
256 #define wxCHECK_GCC_VERSION( major, minor ) \
257 ( defined(__GNUC__) && defined(__GNUC_MINOR__) \
258 && ( ( __GNUC__ > (major) ) \
259 || ( __GNUC__ == (major) && __GNUC_MINOR__ >= (minor) ) ) )
262 This macro can be used to check that the version of mingw32 compiler is
265 #if defined( __GNUWIN32__ ) || defined( __MINGW32__ ) || defined( __CYGWIN__ )
266 #include "wx/msw/gccpriv.h"
268 #undef wxCHECK_W32API_VERSION
269 #define wxCHECK_W32API_VERSION(maj, min) (0)
272 #endif /* _WX_PLATFORM_H_ */
