-
- There are two wxWidgets ports to Mac OS. One of them, wxMac, exists in two versions:
- Classic and Carbon. The Classic version is the only one to work on Mac OS version 8.
- The Carbon version may be built either as CFM or Mach-O (binary format, like ELF)
- and the former may run under OS 9 while the latter only runs under OS X.
- Finally, there is a new Cocoa port which can only be used under OS X. To
- summarize:
-
- @li If you want to test for all Mac platforms, classic and OS X, you
- should test both @c __WXMAC__ and @c __WXCOCOA__.
- @li If you want to test for any GUI Mac port under OS X, use
- @c __WXOSX__.
- @li If you want to test for any port under Mac OS X, including, for
- example, wxGTK and also wxBase, use @c __DARWIN__ (see below).
-
- The convention is to use the @c __WX prefix for these
- symbols, although this has not always been followed.

- Some library features may not be always available even if they were selected
- by the user. To make it possible to check if this is the case, the library
- predefines the symbols in the form @c wxHAS_FEATURE. Unlike
- @c wxUSE_FEATURE symbols which are defined by the library user (directly
- in @c setup.h or by running configure script) and which must be always
- defined as either $0$ or $1$, the @c wxHAS symbols are only defined if
- the corresponding feature is available and not defined at all otherwise.

-
- @beginDefList
- @itemdef{wxHAS_LARGE_FILES, Defined if wxFile supports files more than 4GB in size.}
- @itemdef{wxHAS_LARGE_FFILES, Defined if wxFFile supports files more than 4GB in size.}

+@section page_cppconst_msvc_setup_h Libraries selection for MSVC setup.h
+
+Microsoft Visual C++ users may use the special @c wx/setup.h file for this
+compiler in @c include/msvc subdirectory. This file implicitly links in all the
+wxWidgets libraries using MSVC-specific pragmas which usually is much more
+convenient than manually specifying the libraries list in all of the project
+configurations. However sometimes linking with all the libraries is not
+desirable, for example because some of them were not built and this is where
+the symbols in this section can be helpful: defining them allows to not link
+with the corresponding library. The following symbols are honoured:
+ - wxNO_ADV_LIB
+ - wxNO_AUI_LIB
+ - wxNO_HTML_LIB
+ - wxNO_MEDIA_LIB
+ - wxNO_NET_LIB
+ - wxNO_PROPGRID_LIB
+ - wxNO_QA_LIB

+ - wxNO_EXPAT_LIB
+ - wxNO_JPEG_LIB
+ - wxNO_PNG_LIB
+ - wxNO_TIFF_LIB
